compress powerpoint presentation file size

Reduce the file size of your PowerPoint presentations

If the file size of your presentation is too large, try the following tips to make it more manageable.

Compress pictures in your presentation

Select a picture in your document. The Picture Format tab appears.

On the Picture Format tab, in the Adjust group, select Compress Pictures .

Under Compression options , do any of the following:

Make sure that Apply only to this picture is not selected so that the changes you make here will apply to all pictures in the document.

Select Delete cropped areas of pictures . This option removes the cropped picture data but note that if you delete the cropped picture data, you won't be able to restore it.

Under Resolution , select Use default resolution .

Compress Pictures

Under Compression options , do either of the following:

Select Delete cropped areas of pictures . This option removes the cropped picture data but note that if you delete the cropped picture data, you won't be able to restore it.

Compress Pictures options

Delete image editing data and lower default resolution

By default, when you edit an image, the data from the original is retained (to ensure the image can be restored). Discarding it means that you can't restore the changes you make, but it will reduce your file size. Lowering the default resolution for images also reduces your overall file size.

Go to File > Options > Advanced .

Under Image Size and Quality , do the following:

Select Discard editing data . This option removes stored data that's used to restore the image to its original state after it's been edited. Note that if you discard editing data, you won't be able to restore the image after you edit it.

Make sure that Do not compress images in file is not selected.

Set the image size and quality

Reduce the character set of embedded fonts

To make your presentation more sharable with others who don't have the same fonts in their system, it's typical to embed the fonts you use. However, embedded fonts will increase your file size. To minimize the file increase, embed only those characters used in the presentation.

Go to File > Options > Save .

Embed fonts in the file

Note:  If you've used custom fonts and want others to edit the presentation, select Embed all characters .

Quick Links

Convert your presentation to the pptx format, insert your pictures—don’t copy and paste, do image edits in an image editor—not in powerpoint, compress all of the images in your presentation, don’t use embedded fonts, link to files instead of embedding them, don’t store a thumbnail for the presentation, remove personal and hidden information from your presentation, turn off autorecover, copy everything into a new presentation, a possibility: unzip the presentation and compress it.

Considering that Microsoft PowerPoint presentations are generally accompanied with tons of images, gifs , embedded videos , charts , graphs, and other content, it’s no surprise that you get some pretty big files. Here are a few steps you can take to reduce a presentation's file size.

Large files can be annoying. They take up loads of precious disk space, slow down playback performance, and can cause emails to bounce back due to exceeding the file size limit. You can prevent all of these things by reducing the file size of your presentation.

We’ve mentioned it before, but the first thing you’d think of when considering file size reduction is images—and for a good reason. Image files can be quite large. There are steps you can take to reduce the size, such as compressing the images in the presentation. If you suspect the reason your PowerPoint file is so large is due to images, then be sure to read the article we’ve written on how to reduce the size of Office documents that contain images .

We do have some additional tips to add if you followed these steps but still need to reduce your presentation’s file size.

Microsoft released the PPTX format in Office 2007. Still, it’s not uncommon to see PPT files floating around. So what’s the difference between a PPT and PPTX file? The PPTX version compresses all of the content within the presentation. If you have a PPT file and convert it into a PPTX file, you’ll notice a decrease in the file size.

Converting the file is as simple as pressing a button and choosing the file type. Go ahead and open your PPT file, head over to the “File” tab, and then click “Convert.”

Convert presentation

Windows File Explorer will appear. You’ll notice the Save As type is set as "PowerPoint Presentation." This is the PPTX file type. Click “Save.”

Save as type

Your PPT file will now be converted to a PPTX file. As you can see, the size of the file has been reduced.

reduced file example

HTG Presentation 2 is our PPT file, and HTG Presentation 3 is our PPTX file. Merely converting the file type reduced the size by 335 KB.

While this isn’t a breathtaking drop in file size, we managed to reduce a Word document file size from 6,001 KB to 721 KB. It all depends on what’s inside the file. With any luck, this will be the only step you need to take. If not, keep reading.

It’s tempting to copy and paste an image in PowerPoint instead of using the insert function. This won’t be an issue if you’re not concerned about file size, but if you are, then beware of copy and paste—it may reformat your image to BMP or PNG. Why is this an issue? Both of those file formats are larger than JPG.

png to jpg conversion size difference

You can see in the above screenshot that the PNG file is 153KB compared to the 120KB JPG file of the same image. Each time you copy and paste a JPG file to PowerPoint, and it gets converted to PNG, you’re adding a bit of unnecessary file size to the presentation. Using the insert function will ensure your images are inserted as intended.

When you insert an image in PowerPoint, it’s best to make sure that it doesn’t need any edits. If it does require edits, you’re better off doing it in an image editor. Why? When you use PowerPoint to edit your image, it stores all of those edits as part of the presentation. For example, when you change an image to black and white, PowerPoint retains the full-color image as well. That’s a lot of extra bites being stored.

If you don’t have an image editor ( you do ) or you simply must use PowerPoint, be sure to tell PowerPoint to discard all of that excess data saved from the edits . It won't save you as much space as working in a dedicated editor, but it will help.

You can compress images in PowerPoint one at a time or all at once. If you’re looking to do the latter, here’s how.

Open your presentation, head over to the “File” tab, and then select “Save As” in the left-hand pane.

select save as option

Next, select “More Options,” which you'll find under the area where you would name your file and choose the file type.

More Options in Save as tab

The “Save As” window will appear—this time with a few extra options available to you. Next to the “Save” button, click “Tools.”

Tools in save as dialogue box

In the drop-down menu that appears, select “Compress Pictures.”

Compress pictures option in tools

The “Compress Pictures” window will appear. Here, you can choose the resolution type of the images (based on PPI) in the presentation. You’ll also notice that you’re not able to select the “Apply only to this picture” option in the “Compression Options” group. That’s because, due to the way we accessed this tool, this option isn’t available.

Note: If you do want to compress a single picture, select it and then head to Picture Tools Format > Compress Pictures.

Once you’re happy with your selection, click “OK.”

compress pictures window

Be sure to save your presentation afterward.

We get why you might want to embed fonts—you might be making a Star Wars themed presentation and, as a result, anyone you may be sharing the presentation with is not likely to have those special fonts available to them. Embedding the fonts in your presentation could prevent issues down the line, but it comes at the cost of increased file sizes.

In general, unless you are sure you need to display a particular font, we recommend turning off font embedding.

Head over to the “File” tab and select “Options” at the bottom of the left-hand pane.

Options at bottom of lefthand pane

On the “Save” tab, untick the “Embed fonts in the file” checkbox and then click “OK.”

uncheck embed fonts box

We saved a copy of our presentation with all fonts embedded, without fonts embedded, and with only the fonts used in the presentation embedded. Look at the difference if file sizes:

difference in file size with embedded fonts

Convinced yet?

Consider the difference in file size if you embed an entire YouTube video in your presentation instead of linking back to it. Embedding an entire video will significantly increase the size of your presentation. There are certainly some valuable benefits when embedding a file vs. linking to it (such as when the recipient might not have internet access to play the video), but if the file size is an issue, just don’t do it.

Way back when Office let you save thumbnail images of your presentation so that you could get a sneak preview of the file when searching for it in File Explorer. Windows has grown to be more sophisticated, so it no longer requires the help of Office applications to do this. But, the option is still available.

We ran a little test to see the difference in file size with and without this option enabled. Here are the results:

don't save thumbnail

With the thumbnail option enabled, our file size was 2,660 KB. Without the option enabled, the file size was reduced to 2,662 KB, saving a total of 7 KB.

This is a pretty small save, but when we tested it with a Word document, the difference was significant, showing 721 KB without the option enabled, and 3,247 KB with the option enabled.

While this is a large gap between applications and it’s not exactly clear why the difference is so large, it’s still an option worth exploring. To disable the feature, open your presentation, head over to the “File” tab, and then select “Properties” found on the right-hand side, then “Advanced Properties.”

select properties

You’ll now be in the “Summary” tab of the “Properties” window. At the bottom of the window, uncheck the box next to “Save preview picture,” and then click “OK.”

uncheck save preview image

Microsoft Office will store your personal information (such as author name) and hidden properties within your presentation. Getting rid of this information can save you a bit of space.

Open your presentation, head over to the “File” tab, select the “Check for Issues” option, then select “Inspect Document."

Inspect Document

The “Document Inspector” window will appear. Make sure the “Document Properties and Personal Information” box is checked, and then click “Inspect."

Inspect the document

In the next window, select “Remove All.” The information will now be removed, saving you a few KB of space.

We don’t necessarily recommend this, and it should only be used as a last resort effort. AutoRecover is an essential tool in Office, and if you’ve ever lost a document before saving, then you understand precisely what we mean.

Each time Office uses AutoRecover, it adds a little to the size of the file. To turn AutoRecover off, head over to the “File” tab and select “Options” found at the bottom of the left-hand pane.

In the “Save” tab of the “Options” window, uncheck the box next to “Save AutoRecover information ever xx minutes.”

uncheck autorecover option

If you save and exit out of the presentation immediately, you won’t notice a difference. Over time though, as you continue to progress through the presentation, the AutoRecover feature will add KB to your file.

While you’re creating your presentation, PowerPoint will save various things in the background to help you out. We’ve mentioned how to turn off a lot of these features, delete data PowerPoint saves, and so on, but there’s always a chance something slipped through the cracks, and PowerPoint stored some information you don’t need. Copying your content over to a new presentation may be a good solution to the problem.

This may be a bit of a hassle though as, with PowerPoint, you’ll need to copy and paste each slide (and master slides). Once you do though, the new presentation won’t have any of the previous background saves, AutoRecover information, or previous versions of the file. As a result, you should see a change in file size.

While we can’t tell you exactly how much this will reduce your file size since each presentation will be different, it’s worth a shot.

As we mentioned earlier, a PPTX file is a compressed file (which is why the size is much smaller than an old-school PPT file). This means you can open it with a tool such as 7-Zip or WinRar, extract all the files from your PPTX, add them to a compressed archive, and then rename the archive to a PPTX file extension.

We had some issues here, though.

In Rob’s testing with his Word document, it successfully reduced the size of the file from 721 KB to 72 KB. However, it corrupted the file in the process. In my testing with my 2,614 KB file, it didn’t corrupt it, but it only reduced it to 2,594KB—a total of only 20 KB. We’re unsure what’s at play here, so if you want to give this a go, be sure to have a backup copy of your file before doing so.

That’s all the tips we've got for reducing the size of your PowerPoint presentation. We’re always looking for new and interesting ways to reduce the size of our files, so if you have any tips, let us know in the comment section, and we’ll be happy to test them out!

Compress PPT Online Smallpdf Banner

July 12, 2024 by Hung Nguyen

Learn how to reduce the size of your PPT files by more than half at no cost, using Smallpdf. No watermark, no registration, and no installation.

We’re well into the 21st century, but many email servers still have a 20–25 MB size limit for attachments. This isn’t an inconvenience when you’re sending or receiving simple documents or files. But it can be a severe impediment when you work on presentations and PPT files regularly.

Basic presentations of only a few text-based slides are rarely too large to send via email. But once you start adding charts and images to a PowerPoint presentation with more than 20 slides, the size can rapidly balloon past the email size cap.

Using the compression tools built into Windows and macOS might save you 1–2 MB. Cloud-based storage involves multiple steps for you and the recipient, and file transfer services usually require registration.

Smallpdf offers a simpler alternative that requires no registration and can reduce PowerPoint file size by more than half.

How To Compress a PPT File for Free

Upload your ppt to our compress tool ., choose “basic” once the compress panel appears., once compression is complete, select “export as” instead of “download.”, choose “powerpoint (.pptx),” and on the next screen select “convert selectable text only” and then the “convert” button., after conversion, you can download your document, share it, or save it..

What Happens When We Compress PowerPoint Files

Smallpdf can compress PowerPoint files more effectively than zipping by first converting them to a PDF. During this process, our compressor looks for repeated patterns and data, replacing them with unique identifiers. This results in a much smaller file.

If what you wanted was a smaller PDF, you can download this once the conversion and compression are complete. But to reduce PowerPoint file size, the “Export As” option allows you to turn the PDF back into a PPT file. The layout remains unchanged, and all fields can still be edited in PowerPoint.

Once your file has been compressed and converted, you can either download it to your device, share a link to the file, or save it to your Dropbox or Google Drive account. If you have a Pro subscription, you can also save it to your Smallpdf storage.

One caveat is that compression can sometimes affect non-standard fonts, special characters, and emojis. To reduce the risk of any text in your presentation from being changed, you can embed the fonts used in your PowerPoint file.

  • With your presentation open in PowerPoint, select “Preferences.”
  • Select “Save” under “Output and Sharing.”
  • In the panel that opens, check the “Embed fonts in the file” option.

Emojis are usually replaced by the “undefined” glyph—a rectangle with an X—during compression. If your presentation must include emoji, turn them into images first and add the image to your slides.

Other Measures to Reduce PowerPoint File Size

There are a few other steps you can take to make your PPT file smaller before compressing it.

Each high-resolution image in your presentation can add 2 MB or more to the file size. Instead of removing images essential to the presentation, try optimizing them first. This guide will take you through the steps to using our Compress tool on your images. Once you have compressed all your images, replace the high-resolution version with the optimized version.

You can also compress images using PowerPoint. Go to File and select “Compress Pictures”. This will give you a variety of options that you can experiment with to see what effect it has on the image quality and the file size.

Embedding videos in your presentation will also inflate the file size. Although Smallpdf can’t help with compressing video files, there are other online services that can. Alternatively, consider uploading the video to YouTube and then adding a link to it in the presentation.

Once you have finished compiling your PowerPoint presentation, run through all the slides again to ensure all unused slides and slide masters have been removed. You can reduce PowerPoint file size substantially by following these steps, and then you can use our Compress tool to make it even smaller.

Maintaining Quality and Formatting

Whenever you compress PowerPoint files, there is always some risk of losing quality. Text and vector graphics will remain clear with well-defined edges, but other images could end up with slightly blurred edges. Opting for Basic compression reduces this risk while still giving you a much smaller file. But always check the results before sending your file.

Compress-PowerPoint-Presentations-Online-2

Our compression tool also retains the original formatting. You can still edit any text in your presentation, along with shifting, resizing, or removing individual images.

When uploading a file to our Compress tool, you’re uploading a copy. The original file is never removed from your device. So, if you are unhappy with any results, you still have the uncompressed original to work with.

Go Pro and Get More Done

Smallpdf is free to use, and you don’t need to create an account. However, you are limited to two downloads a day using any of our more than 20 tools . If you create a Smallpdf account, you unlock a 7-day free trial with unlimited downloads and access to other Pro features. You can also download our Windows app, allowing you to compress PowerPoint files, JPGs, and other file types offline. After 7 days, you can switch back to a free plan with limited downloads or subscribe to a Pro, Team, or Business plan.

You're in good company:

Why compress ppt files.

PPT also goes by the name of PowerPoint Presentation and are used in all walks of life including the home, school and at work. PPT files can range in size depending on the content of the presentation. If a presentation contains a lot of images or videos then the file size can be especially large. Even just one high resolution image - such as a BMP - can increase the size of a PPT file tenfold. When a user complains that they have run out of space in their mailbox it is typically because they've been sent one too many large presentations. It is not surprising then that there is such a need to compress PPT files so that they do not take up as much storage and can be more easily shared. Using the Zamzar PPT compression tool, individual (and sizeable) elements - such as pictures and videos - are compressed bringing the overall file size down. Once compressed, the PPT (including the images and video within it) does not suffer from any noticeable loss in quality despite the file size being shrunk. It's worth remembering that if you receive a PPT file and need to send it on you can always put it through the Zamzar compression tool before you do so.

Any Operating System

It doesn’t matter what operating system you’re running; as long as you have a web browser, Zamzar can convert your files.

High Quality

Zamzar prides itself on the highest-quality file conversion, so you won’t be able to tell the difference between your uploaded file and your newly converted file.

Cloud Based

You don't need to download any software to convert a file with Zamzar. All you need is access to the internet and you can then convert your file with us online.

10 Ways to Compress PowerPoint Presentations to Reduce File Size

Compress PowerPoint presentations to reduce file size represented by large and small PowerPoint icons.

10 Strategies to Compress or Reduce the Size of Large PowerPoint Presentations

by Avantix Learning Team | Updated September 21, 2023

Applies to: Microsoft ®  PowerPoint ® 2013, 2016, 2019 and 365 (Windows)

You can compress or reduce the size of large PowerPoint presentations in several ways. The most common strategy to reduce the size of a PowerPoint file is to compress pictures, video and audio. However, you can also use other methods to make files smaller including saving media and PowerPoint files in other formats and converting or removing embedded objects.

In this article, we'll look at 10 ways to compress or reduce the size of a PowerPoint presentation:

  • Compress pictures
  • Insert pictures instead of copying and pasting
  • Use smaller image files
  • Convert images to a different file type
  • Save a copy of images with artistic effects
  • Compress audio and video
  • Link to audio or video files
  • Convert Excel charts and other embedded objects
  • Save a copy of large PowerPoint files
  • Save a copy in PDF format

Note: Buttons and Ribbon tabs may display in a different way (with or without text) depending on your version of PowerPoint, the size of your screen and your Control Panel settings. For PowerPoint 365 users, Ribbon tabs may appear with different names. For example, the Picture Tools Format tab may appear as Picture Format.

To view file size in PowerPoint:

  • Click the File tab in the Ribbon.
  • Click Info. In the Properties area, file size is listed beside Size.

Microsoft PowerPoint File Info pane which displays properties including file size.

Once you've completed the following strategies, close and save the PowerPoint file, reopen it and check the file size again. You can also view file size in Windows 10 File Explorer or Windows Explorer in older versions of Windows.

1. Compress pictures

One of the most common ways to reduce file size is to compress one or all of the pictures in your PowerPoint file. You may want to try this with one picture at a time to be sure you are satisfied with the result after compression.

To compress a picture:

  • In Normal View, select a picture on image on a slide.
  • Click the Picture Tools Format or Format Picture tab in the Ribbon.
  • In the Adjust group, click Compress Pictures. A dialog box appears.
  • Select the check box to Apply only to this picture if you want to compress only the current picture or uncheck this option if you wish to compress all pictures in the presentation.
  • Select the check box to Delete cropped areas of pictures if you have cropped images and want to permanently delete the areas you have removed by cropping.
  • Choose the desired document resolution.

PowerPoint compress pictures dialog box to reduce file size.

Don't forget to check pictures in Slide Master View (click the View tab in the Ribbon and then click Slide Master) as you may want to compress or delete those images as well.

Also, be sure to check image(s) after you compress them to be sure to are satisfied with the quality of the image(s). If you create a copy of the presentation before compressing the image(s), you can revert to the original if necessary.

2. Insert pictures instead of copying and pasting

It's best to insert pictures, rather than copying and pasting (or dragging and dropping) into the PowerPoint file. When you copy and paste (or drag and drop) an image into a presentation, it can lose compression, change file type and also bring in other data that can increase file size.

To insert a picture onto a PowerPoint slide:

  • In Normal View, display the slide where you want to insert a picture.
  • Click the Insert tab in the Ribbon and click Pictures (2013 and later versions) or Picture (2010). You can also click the Pictures or Picture icon in a placeholder on a slide. A dialog box appears.
  • Navigate to the location of the picture.
  • Select the picture and click Insert or double-click the picture.

You also have the option of linking to a picture file by clicking the arrow beside Insert in the Insert Picture dialog box and then choosing Link to File. However, the picture is not actually "in" the file (which reduces file size) and if you email the document, the pictures will not be included. If you use this strategy, it's best to copy the picture to the same folder as the PowerPoint presentation and be sure to bring the entire folder with you when you deliver the presentation.

3. Use smaller image files

It's best to insert pictures in smaller sizes to reduce the size of your PowerPoint files. For example, if you are inserting pictures from a phone taken at a high resolution, this will result in larger PowerPoint decks. Create, save or send images at a lower resolution and insert the lower resolution images into your PowerPoint files.

If you're using stock images, select images at the lowest resolution (at the quality level you require). You can also open an image in an image editing program (such as Microsoft Picture Manager or Adobe Photoshop) and then save it at a lower resolution.

In PowerPoint 365, one of the biggest culprits causing inflated file size is 3D models. Although 3D models are not inserted as pictures but rather as 3D models, they are images. One 3D model we inserted took up 17 MB of space. You can't compress 3D models like other types of images so you may need to delete 3D models or use a picture instead of a 3D model if file size is an issue.

4. Convert images to a different file type

Prior to inserting an image in PowerPoint, you can open it in an image editing program (such as Microsoft Picture Manager or Adobe Photoshop) and then use Save As to save the image in another format.

The format that will result in the smallest size is usually JPEG (Joint Photographic Experts Group format) or JPG. The JPEG compression algorithm significantly reduces the file size of images.

You can also save images in PowerPoint in different formats:

  • Right-click the picture. A drop-down menu appears.
  • Select Save As Picture. A dialog box appears.
  • Navigate to the folder where you want to save the image.
  • Enter a name for the file and select a format such as JPG or PNG.
  • Click Save.
  • In the PowerPoint presentation, delete the original image.
  • Click Insert and then click Picture(s).
  • Navigate to the location with the image you saved.
  • Double-click the image.

5. Save a copy of images with artistic effects

When you apply an artistic effect to an image, PowerPoint retains two copies of the image (the original and a copy with the artistic effects). This allows the user to reset the image but can significantly increase file size. Compressing pictures also doesn't normally have any effect on images where you have applied artistic effects.

If you have applied an artistic effect (such as blur) to an image, you can reduce file size using the following method:

  • Right-click the image with the artistic effect. A drop-down menu appears.
  • Enter a name and select a file type (usually JPG or PNG).
  • In the PowerPoint presentation, delete the image with the artistic effect.
  • Navigate to the location with the image you saved with the artistic effect.

6. Compress audio and video

In 2010 and later versions of PowerPoint, audio and video files are copied into presentations rather than linked to the original files. You can improve playback performance and reduce PowerPoint file size by compressing audio and video files in your presentation.

Files can be compressed at different quality levels.

In PowerPoint 2013 and 2016, you can compress to the following quality levels:

  • Presentation Quality – select this option to save space but maintain overall audio and video quality.
  • Internet Quality – select this option and quality will be comparable to media which is streamed over the web.
  • Low Quality – select this option if space is limited, such as when you are sending presentations via e-mail.

Compress media options in PowerPoint older versions to reduce file size.

In PowerPoint 2019 and 365, you can compress to the following quality levels:

  • Full HD (1080p) – select this option to save space while maintaining overall audio and video quality.
  • HD (720p) – select this option to save space and the quality will be comparable to media which is streamed over the Internet.
  • Standard (480p) – select this option when space is limited, such as when you are sending presentations via e-mail.

The following compression options appear in PowerPoint 2019 or 365:

Compress media options PowerPoint 2019 or 365 to reduce file size.

Note: Some older video file formats may not compress or export properly. Embedded subtitles and alternate audio tracks will be lost in the compression process.

To compress media in PowerPoint:

  • Open the presentation that contains the audio or video files you want to compress.
  • Save a copy of the presentation so you can retain a copy of the file with the original media.
  • In the copy, click the File tab in the Ribbon.
  • Click Info.
  • In the Media Size and Performance area, click Compress Media. A dialog box appears.
  • Select the desired compression option. A dialog box appears indicating that media compression is in progress. PowerPoint will indicate how much space is saved.
  • When compression is complete, click Close.

7. Link to audio or video files

You also have the option of linking to audio or video files. When you insert an audio or video file, click the arrow beside Insert in the Insert dialog box and then choose Link to File. Linked audio or video is not actually "in" the presentation (which reduces file size) and if you email the presentation, the media files will not be included if you have linked to audio or video files. Linking was the default behavior in PowerPoint 2007 and earlier versions for video and larger audio files.

If you choose to link to audio or video files, t's best to copy the media files to the same folder as the PowerPoint presentation and be sure to bring the entire folder with you when you deliver the presentation.

Note: You cannot apply certain types of formatting to linked video files.

8. Convert Excel charts and other embedded objects

Embedded objects such as Excel charts or worksheets can also increase file size. If you convert embedded objects to images, it can impact the size or your presentation. You can also reduce file size by breaking links to Excel files.

If you want to convert embedded objects into pictures, you can ungroup them or cut and paste them back into PowerPoint.

To ungroup an object:

  • Select the chart or embedded object.
  • Click the Format tab in the Ribbon. This tab may appear as Drawing Tools Format, Drawing Format or Shape Format.
  • Select Group and then Ungroup. A dialog box appears asking if you want to convert the object to a PowerPoint object.

To cut an object and paste it back into a presentation as a picture:

  • Select the embedded chart or object.
  • Press Ctrl + X to cut it.
  • Click the Home tab in the Ribbon.
  • Click the arrow below Paste to display the drop-down menu and then choose Paste Special.
  • Select an image type (such as JPEG) and click OK.

 PowerPoint paste special dialog box to compress embedded files and reduce file size.

If you have links to Excel files, you can reduce file size using Edit Links to Files. Check out How to Break, Update or Change Links to Excel Charts or Worksheets in PowerPoint for more information on how to break links.

9. Save a copy of large PowerPoint files

It's a good idea to save a copy of a large PowerPoint files periodically using Save As and give the file a different name (i.e. Sales Presentation and the date). If you save a copy using Save As, version history and some editing data is removed during the process and this will reduce file size. This can also help avoid corrupted files.

To save a copy of a PowerPoint presentation:

  • Choose Save As. If necessary, click Options or More Options. A dialog box appears.
  • Navigate to the desired location.
  • Enter a new name for the presentation.

10. Save a copy in PDF format

It's also common to save a copy of a presentation as a PDF (portable document format) file to reduce the size and then share it with others. You can compress images during the process.

To save a PowerPoint presentation as a PDF (and compress images):

  • Choose Save As and then click Options or More Options if necessary. A dialog box appears.
  • Navigate to the desired location and enter a name for the file. You can use the same name since the extension will be different (PDF).
  • Under File Type, select PDF.
  • Click Tools on the bottom right of the dialog box. A drop-down menu appears.
  • Select Compress Pictures. A dialog box appears.
  • Click the desired compression option.

Large file size is a common problem in PowerPoint and you can use these strategies to reduce the size of your PowerPoint presentations. Compressing the size of your decks should also help to improve speed and avoid crashes.

How to Compress a PowerPoint Presentation

Carla Albinagorta

PowerPoint is an amazing audiovisual tool for presentations. It allows you to add images, graphs, videos, and pretty much everything you might need in order to craft the perfect complement. But precisely because of this, sometimes PowerPoint documents can end up taking a lot of space. So, how do you share your presentation when it’s just too big? Here you’ll learn how to easily compress a PowerPoint presentation to share it with whomever you want.

how to compress a PowerPoint presentation

How to compress a PowerPoint presentation directly

Thankfully, PowerPoint has some compress options built into it, so learning how to compress a PowerPoint presentation is a very straightforward business. You have 2 main options.

1- How to compress images in a PowerPoint presentation

a. Select the image you want to compress. Once you do this, the Picture Format tab will appear at the end of your tools ribbon.

b. Select Compress Pictures

Take into consideration that if you untick the Apply only for this picture option, all of the PowerPoint presentations images will be compressed. If you’re looking for how to compress a presentation will a lot of images, then this one is a great option for you.

2- How to compress a PowerPoint with a video

If your presentation has a video in it, chances are it’s a pretty big file! To compress your PowerPoint document just follow these steps:

a. Go to File > Info

b. Choose the Compress Media option. Just like with images, it will give you quality options, and pick the one that fits better your needs.

c. A new window will pop up to show you the compressing progress. Once it’s completed, it will also tell you how much space are you saving by compressing your PowerPoint media. Just click Close when the process is completed, and you can go back to work on your presentation.

Other options for sharing your presentations

However, if you compress a PowerPoint presentation you’ll probably lose some quality. The more you compress an image, the more quality it will lose. This is especially important to take into consideration if you’re planning to use a big projector, as it will make bad quality images pretty noticeable.

If compressing your PowerPoint presentation it’s just not doing it for you, of you don’t want to sacrifice some of its quality, here are some alternative options for sharing your files:

1- ZIP Files

A pretty straightforward way on how to compress a PowerPoint presentation is simply to use a ZIP File. ZIP files allow you to compress many documents into one directory. Windows 10 has built-in an option for file compressing. You just need to go to your File Explorer and right-click the PowerPoint presentation to compress. Select Send to > Compressed (zipped) folder . And that’s all!

If you’re not working with Windows 10, you can download a file archiver and compressor software, like WinZip or WinRAR (for earlier Windows versions). These will allow you to easily compress PowerPoint presentations, and pretty much everything else. There are many free compressors available, so it’s just a matter of finding the one that suits you the best.

Take into consideration that, when sending a compressed PowerPoint presentation in this way, the receiver must also have a compressor software, like the ones mentioned above. This will allow them to decompress the document and get access to it. It’s also important to know that ZIP Files might not compress a PowerPoint presentation enough for it to be sent by e-mail. It depends mainly on the size of the original file. Thankfully, there are other options for sharing your presentations!

2- Cloud Sharing

Cloud sharing is an excellent way to share files that are otherwise too big to send by e-mail. You don’t even need to know how to compress a PowerPoint to use this method. You just need to register in a cloud storage service, like Google Drive or Dropbox , and upload your presentation. Once it’s uploaded, you can send the link to whoever you want, and they will instantly gain access to it.

If it’s a particularly big document, you can even mix this option with the previous one. You can compress your PowerPoint presentation in a ZIP file, and upload the compressed version. This will make it easier and quicker for you to upload it, and for your receivers to download it.

3- PDF format

Converting your presentation to a PDF document is one of the easiest ways to compress your PowerPoint presentation in order to share it. It will immediately lower your file size and allow you to share it through all kinds of means, including e-mails.

However, one very important thing to take into account when using this method to compress a PowerPoint presentation is that you’re changing the file’s format. And this had both its ups and downs. For starters, this means that whoever receives it will not be able to access it as a PowerPoint presentation. Your slides will be converted to PDF pages, and while images and graphs will likely remain, any videos or voice notes in your presentation will not be added in the converted document.

But this also has an ad additional advantage. This means the receiver will not be able to edit it. If you’re sending a PowerPoint presentation and you don’t want it altered or copied in any way, sending it as a PDF file is a good option. It all depends on what you’re looking for!

share your PowerPoint presentation

Hopefully, you have now learned how to compress your PowerPoint presentations. Now you can share them with whomever you like, whether it is team members, coworkers, or your audience. Good luck!

How to compress a PowerPoint file so that it loads faster and doesn't take up as much space

  • You can easily compress a PowerPoint file's size, which makes it easier to share and save.
  • When you compress your PowerPoint, you'll have to reduce the quality of any music, videos, or pictures you have in your slideshow.
  • Once you've compressed your PowerPoint, it will load faster, but the media in it may not look as good.
  • Visit Business Insider's Tech Reference library for more stories .

At some point in your slideshow-creating life, you've probably saved a PowerPoint presentation and realized that the file size is entirely too large. 

Larger file sizes make PowerPoints more difficult to send and save, and they also make each slide take longer to load.

One of the easiest ways to quickly reduce a PowerPoint presentation's file size is to compress it. When you compress a PowerPoint, you'll reduce the quality and size of every media file in the presentation. This includes videos, audio clips, animations, and photos.

If you compress them down to an appropriate size, your file size will be much smaller. However, your photos, videos, and other media probably won't look or sound as sharp.

Here's how to compress your media files in PowerPoint on a Mac or PC.

Check out the products mentioned in this article:

Apple macbook pro (from $1,299.00 at apple), acer chromebook 15 (from $179.99 at walmart), how to compress a powerpoint file on a pc.

1. In the ribbon or menu bar at the top of the screen, click "File." Make sure that "Info" is selected in the left sidebar.

2. Click "Compress Media." Depending on whether your version of PowerPoint was made before or after 2016, this button will either be next to the label "Multimedia" or "Media Size and Performance."

3. Choose one of the three options for media quality from the dropdown menu. These will differ based on which version you have as well, but they boil down to: 

  • Select the highest quality option if you want to maintain high quality media for in-person presentations. 
  • Select the middle option for quality akin to media found on the internet. 
  • Select the lowest quality option if your file needs to be as compressed as much as possible — for example, if you need to send it via email.

How to compress a PowerPoint file on a Mac

In the Mac version of PowerPoint, you can only reduce the file size of images, not videos or music.

To do this:

1. Open your PowerPoint slideshow and click "File" in the menu bar at the top of the screen. If you only want to compress specific images, select them before clicking "File."

2. In the dropdown menu, click "Compress Pictures..."

3. You'll be shown a "Compression Table," which lists all the different ways you can compress the file. You'll have three main options:

  • "Printing" will keep your pictures at the highest quality possible.
  • "Viewing on screen" will reduce the quality of your pictures by about 30 percent.
  • "Sending in an e-mail message" will compress them by another 30 percent or so.

You can also pick the fourth and last option, which will keep each picture's current resolution, but try to reduce the file size in other areas.

4. Select whether you'd like to delete parts of your pictures that have been cropped out — doing so will help reduce the file size.

5. Choose whether you'd like to compress every picture in the slideshow, or just the ones that you selected beforehand. Once you've decided, click "OK."

How to Compress PowerPoint Presentations

How to compress a PowerPoint presentation and reduce its size. Learn how to minimize PowerPoint file size.

Many users, when sharing PowerPoint files via email, can end up realizing that the file is too big to be sent via their email service provider because of its excessive file size. While there are many third-party apps that enable sending large files via sharing links, not only can they be less secure to use for confidential documents, but the files might take a while to download by the recipient due to the heavy file size. therefore, Compressing a PowerPoint presentation can help you avoid such issues.

Compress a PowerPoint Presentation File

There are different methods by which you can compress a PowerPoint file and elements within the file to reduce the file size and make your slide deck more manageable.

1.  Compress Images in PowerPoint

The most common method to reduce the file size of a PowerPoint presentation is to compress slide images. This method is also quite useful if you’re wondering how to compress a ppt file for email since it provides the option to reduce the images down to a very low resolution of 96 PPI, which is usually sufficient to make the presentation small enough for an email attachment.

To compress one or more images in PowerPoint, select an image from the presentation, go to the Picture Format tab, and select Compress Picture from the Adjust menu.

Compress pictures in PowerPoint to fully compress PowerPoint presentations

From the dialog box that appears, you can choose various compression options. If you want only to compress the selected image, check Apply only to this picture checkbox.

The compression options available from the given dialog box can be used to reduce the size of the current or all images in the presentation file for print (220 PPI), web (150 PPI), and email (96 PPI), or you can choose the default resolution.

2. Compress Video and Audio in PowerPoint

Video and audio files can take up a lot of space and make PowerPoint presentations difficult to manage due to their large file size. If you have media files added to PowerPoint that are heavy, your presentation might also lag in SlideShow mode.

To compress video and audio files in PowerPoint, go to File > Info > Compress Media . Select a lower resolution of the media files from the drop-down menu to reduce their file size.

Selecting compress media options to compress a PowerPoint presentation

This will shrink the PowerPoint file size and reduce the file size for video and audio files, with information regarding how much the files were compressed.

It is also important to note that if you use audio in your presentations, MP3 files typically compress the audio more than WAV files. To reduce the file size of your presentations with audio, consider inserting MP3 audio files into your presentation, over the WAV format.

6. Compress a PowerPoint File using a File Compression Format

To share a PowerPoint file online in a compressed format, you can convert it to a ZIP file or use a number of formats supported by your operating system or third-party apps such as RAR, 7z, GZIP, TAR, XZ, WIM, etc. The compression feature is often integrated via the right-click context menu or long tap for mobile operating systems.

Some of the most famous tools known to provide a high file compression ratio and various security features for file compression include 7-Zip, WinRAR, WinZIP, PeaZip, etc.

Compressing your PowerPoint presentation can help reduce the file size, making it easier to share via email, improve loading times, and reduce storage space. It also ensures that the recipient can quickly download and access the presentation.

The most common method is to compress the images in your presentation: – Select an image in your presentation. – Go to the Picture Format tab. – Click on Compress Pictures in the Adjust group. – Choose the desired compression options (e.g., for print, web, or email).

If the media quality is unsatisfactory, you can compress the media files separately before adding them back to your presentation using third-party tools. Tools like HandBrake, Xilisoft, and Freemake can help you achieve better compression results.

To reduce the file size by removing unnecessary elements: – Review each slide and identify heavy graphics, images, and other elements that can be removed or simplified. – Use the Slide Master view to make global changes to the slide layouts, reducing the number of heavy elements across all slides.

Yes, you can replace media files with links to online sources or embed content directly from websites like YouTube. This reduces the file size significantly by not storing large media files within the presentation.

You can convert your PowerPoint presentation to a PDF: – Go to File > Save As. – Choose PDF from the file format options. – Save the file. This will remove media files and significantly reduce the file size.

Yes, you can use file compression tools like 7-Zip, WinRAR, or WinZIP: – Right-click on the PowerPoint file. – Select Send to > Compressed (zipped) folder. – Alternatively, use third-party tools to compress the file into ZIP, RAR, or 7z formats.

The potential downsides include: – Loss of media quality due to compression. – Incompatibility issues if the recipient does not have the required software to decompress the file. – Reduced functionality if converting to a different format like PDF, as interactive elements may be lost.

To work with full compatibility: – Use common compression formats like ZIP. – Provide instructions or links to software if using less common formats like RAR or 7z. – Consider sharing a link to an online version of the presentation if possible.

Compressing PowerPoint files can have pros and cons, including loss of media quality or inability of the recipient to open the file if it’s in a compression format that requires a specific app that he/she might not have. Therefore, you should pick a mode of compression that is convenient enough for you and the recipient of the file.

A PPT file can contain several different types of information such as text, bulleted points, images, multimedia and other embedded OLE objects.

Compress PowerPoint to reduce the file size

02.12.20   •  #powerpointtips.

Sometimes, the file size of your PowerPoint presentation can get very big. In some cases, that can be annoying, e.g. when trying to send the slides via email, but not being able to do so because the file is too large. Usually, pictures and videos are the reason why presentations become too big. The good news are that you can easily compress pictures and embedded media files by following the steps listed below.

Compress images

Compress videos and audios.

  • Convert PPT into a PDF file
  • Get rid of 3D-models

Compress PPT as ZIP- file

PowerPoint offers the option to compress all images at once or choose single pictures to reduce their file size. Keep in mind, that compressing an image will automatically reduce its quality as well. If you don't need to reduce the file size, better use the highest quality resolution as possible.

There are two ways to compress images within your PPT file which nearly work the same way:

Compress selected pictures

  • Select the image you want to compress or any picture if you wish to reduce the size of all graphics
  • Navigate to the Picture Tools Format tab and select Compress Pictures

PowerPoint Picture compressing

  • A new menu pops up. Choose your compression options and make sure to check "Delete cropped areas of pictures" and uncheck "Apply only to this picture" (if you want to compress all images)
  • High fidelity: preserves quality of the original picture
  • HD (330 ppi): good quality for high-definition (HD) displays
  • Print (220 ppi): excellent quality on most printers and screens
  • Web (150 ppi): good for web pages and projectors
  • E-mail (96 ppi): minimize document size for sharing
  • Use default resolution

Compress all images while saving the PPT file

  • Open your presentation. Go to File in the PowerPoint menu
  • Click Save as and then Browse
  • In the window that opens, click on Tools (right beside Save )
  • Select Compress Pictures and choose the resolution you need To save even more space, you can additionally choose Delete cropped areas of pictures to remove the parts of pictures which you cropped in PowerPoint.
  • Click OK and then Save

how to save and compress pictures

Video and audio files can increase your PPT size a lot. It's a good idea to compress those if you want to make some space. Some PowerPoint versions make it possible to decrease the media size in PPT but if this option is missing in your program, online video compressors are the solution.

Compress videos and audios in PPT

  • Go to File in the PowerPoint menu
  • Open the Compress media drop down
  • Choose a compression file size. Don't reduce the quality too much and check if the appearance of your media doesn't look too grainy on the actual projector you will be presenting on

PowerPoint Picture video compressing

Online video compressor

There are plenty of online video compressors which you can use to reduce the video size in advance. For example, the website FreeConvert makes it easy to decrease the file size without having to download anything. This way you can integrate a smaller media file into PPT.

PowerPoint media online compressor

Links instead of videos

Instead of importing a video to your PPT slides, including a link to your PowerPoint presentation can save a lot of space. If your video is somewhere on YouTube or other online video-sharing platforms, include a link and use it when you're presenting. But notice: a link can only be used, if you're connected with wifi. Watching videos online, can take time and a bad connection might give you some unwanted breaks during your presentation. In this case, saving the video on your disk and opening it separately can save time and still reduce the size of the PPT.

link instead of video in ppt

Convert PPT to PDF

By converting a PowerPoint file into a PDF, the size will reduce automatically. During the process, images get compressed and some media (audio, videos, 3D models..) get removed. If you want to change the PowerPoint slides at all time, this method might not be the right one for you, as PDF files can't get edited the way a PowerPoint can. Hence, converting PPT into PDF only makes sense if your presentation will work as a handout and if the PDF files options are enough for you.

  • Click Export
  • Hit the Create PDF/XPS button
  • Choose a location in which you want to save your PDF file
  • Click Publish

Convert PPT into PDF

Get rid of 3D models

The Office 365 subscription makes it possible to add 3D models to your PowerPoint slides. Nevertheless, those media require much space since they transport a lot of information. In order to minimize the PPT file, exchanging the 3D model with a normal image will easily reduce the size of your PowerPoint file.

add 3d model to PowerPoint

If you need to share your PPT with someone, a ZIP- file format might help you to reduce the size of the PowerPoint. Even though, this method can save some place temporally, it might not be enough to send it via email. Uploading it to file-sharing platforms, such as GoogleDrive, DropBox, OneDrive or other websites and sharing its link to download the PPT, can be the better option. (Using an USB for sharing the presentation without the need to decompress anything would be the best solution)

compress powerpoint presentation file size

Here's how to convert a PPT into a ZIP- file format:

  • Select the file you want to minimize in the File Explorer
  • Right-Click the file and hit Send to
  • Choose the Compressed (zipped) folder option

compress PPT into ZIP

If you want to decompress a ZIP- file into its original PowerPoint format:

  • Right-Click on your ZIP- folder
  • Select Extract All... or the similar operation of your program
  • Choose a File Location to extract your file to, or extract it at the place you are currently at

decompress ZIP into PPT

How can I reduce the size of a PowerPoint file?

There are several ways to reduce the file size of a PowerPoint. You can compress images, videos and audios, convert your presentation into a PDF file, get rid of 3D models or compress the PowerPoint as a ZIP-file. We explained for you how all of this works in our blog.

How do I compress a video in PowerPoint?

To compress videos in PowerPoint, go to "File" in the PowerPoint menu and then click on "Info". Then open the drop-down menu "Compress media" and select the size of the compression file. Be careful not to reduce the quality too much and check that the quality of your video on the projector you will be presenting on is not too bad.

The big change in PowerPoint 2007 was that the stable binary file format of 97-2003 (.ppt files) was replaced as the default by a new zipped XML-based Office Open XML format (.pptx files). Microsoft's explanation of the benefits of the change included: smaller file sizes, up to 75% smaller than comparable binary documents; security, through being able to identify and exclude executable macros and personal data; less chance to be corrupted than binary formats; and easier interoperability for exchanging data among Microsoft and other business applications, all while maintaining backward compatibility.

Optimize PowerPoint File Size: 5 Tips for Reducing the Size of Your Files!

It is still a common issue in offices today: employees from your company’s overseas branches send you the “latest presentation” via email. However, what arrives in your inbox is a 30-megabyte attachment that not only clogs your email but also slows down your computer when opened.

Furthermore, many companies still impose fixed maximum sizes for email attachments. As a result, there are instances where you may not receive the presentation at all. However, this scenario can be prevented with a few simple measures. Today, we’ll share 5 tips on how to optimize file sizes.

File Size Optimization: Here’s How!

Aim for a target size of approximately 5 megabytes or less for your presentations. This ensures that your PowerPoint file will reach the recipient as an email attachment. Follow these simple tips to reduce the file size of your PowerPoint files:

1. Remove Unused Slides, Pictures, and Videos

This is especially relevant for presentations that are edited by multiple people over an extended period. Often, there are numerous hidden old slides that may still contain images and videos, which can significantly impact the file size.

In such cases, delete all irrelevant slides and content from the presentation and save a new version. This can noticeably reduce the file size.

2. Compress Inserted Images

PowerPoint provides an integrated function to compress images in a presentation. To do this, open the presentation and go to “File,” then select “Save As.” Click on “Browse” in the newly opened window, then click on “Tools” at the bottom and choose “Compress Pictures.”

Compress PowerPoint File Size

Select the option “Delete cropped areas of pictures” and set the target output to 150 or 96 ppi. If your recipient plans to print the presentation, leave the target output at 220 ppi. For more information on compressing images in PowerPoint, check our article on the subject.

Compress PowerPoint File Size

You can find more information in our articel “ Compress Images “.

3. Discard Editing Data for Images

This option can further reduce the size of presentations. Go to the “File” tab, then select “Options. ” Under “Advanced,” check the box next to “Discard editing data” under “Image Size and Quality.” Keep in mind that after enabling this option, changes made to images cannot be undone.

Compress PowerPoint File Size

4. Avoid Creating Image Effects with PowerPoint

Avoid using PowerPoint’s image tools to edit your graphics and photos. For example, the image tools offer the option to apply “Artistic Effects” to your images. However, PowerPoint creates two image files – one for the original and one for the edited image with the artistic effect.

As a result, the overall file size increases with more images attached to the presentation. Instead, use a separate image editing program for effects and other adjustments. Insert the finished edited images into your presentation.

5. Check the Master Slide

When copying a slide from one presentation to another, it’s possible to unintentionally include the master slide from the source presentation in the target presentation, thus increasing its file size. To avoid this unnecessary increase in file size, always paste copied slides into the target presentation using the right-click option “Use Destination Theme.”

After completing your presentation, it’s always a good idea to check the master slide view. There, you can verify if any unnecessary master slides have been inadvertently included through copying and delete them if necessary.

Extra Tip: Use File Size Optimization Tools

There are various tools available that allow you to reduce the size of PowerPoint and other Office files. A popular tool is for example PowerShrink . Both software options allow you to shrink file sizes without any loss of quality. If you want to try out these tools, you can download and test their free trial versions.

Conclusion: Easily and Quickly Optimize Your File Size with Our Tips!

In presentations, file sizes can quickly become too large. To ensure that you and your colleagues can edit and send the presentation without any issues, it’s important to keep the file size below 5 MB. With our tips, you can easily and quickly optimize your file size! Give it a try!

2. Double-click on one of the images to open the Picture Format pane.

3. In the pane, click on Compress Pictures .

Instead of copy-pasting, try inserting your images into PowerPoint. Here’s how:

1. Go to the Insert tab on the ribbon and click on Pictures.

1. To insert videos from a link, go to the Insert tab on the ribbon and click on Vi deo > Online Videos under the Media group at the top-right.

Top Tips to Optimize PowerPoint File Size

Rohit Khariwal

One of the common problems in PowerPoint is a large file size which makes it difficult to access or share your presentation. Large files also occupy too much space on your computer, and your system slows down when you open that file. Some organizations impose limitations on maximum file sizes for email attachments, which further prevents you from sending your large-sized presentations over email. 

Well, this issue can be mitigated by compressing or reducing the size of your PowerPoint file! Wondering how you can do it without losing the quality? Just follow the below given simple measures.

How can compressing a PowerPoint file help?

Compressing a PowerPoint file helps you in several ways-

  • Easy Sharing: Small-sized files are easy to share via email.
  • Improves Accessibility: Makes your presentation accessible on all devices, including mobile, improving collaboration.
  • Saves Storage Space: Compressed files occupy less space on your computer, leaving room for storing more important documents.
  • Enhances Productivity: Compressed files are easy to upload and download, which reduces waiting time and improves your productivity.

Methods for Reducing the Size of Your PowerPoint File

1. reduce the size of images.

Images are a great way to make your presentations visually appealing; however, they may increase the size of your PowerPoint file. 

You can compress image size by following these steps-

Step 1 – Select the image you want to compress.

Step 2 – Click on the ‘Picture format’ tab and choose ‘Compress pictures.’

Compress Pictures 1

Step 3 – Under the ‘Compression options’ menu, select the box labeled ‘Apply only to this picture,’ if you want to compress the selected image only. Uncheck the box if you want to compress all the images.

Step 4 – If you have cropped an image, check the box labeled ‘Delete cropped areas of pictures’ to remove the cropped section. 

Step 5 – Select the resolution for your image from the ‘Resolution’ menu under the ‘Compression options’ menu. 

Step 6 – Click ‘OK.’

Compress Pictures 2

2. Remove Unnecessary Elements

The PowerPoint file size can be reduced considerably by removing irrelevant videos, pictures, slides, and unused/duplicate layouts.

Follow these steps:

Step 1 – Click View > Slide Master.

View Slide Master

Step 2 – Review your slide layouts and check if there is any media that you can compress. Right-click on unused layouts and select ‘Delete layout.’

Step 3 – Click View > Handout Master.

Handout Master

Step 4 – Check the handout templates and remove unwanted graphics or handout masters.

Step 5 – Click View > Notes Master.

Notes Master

Step 6 – Search for large or unused/irrelevant graphics and compress or delete them.

3. Use Smaller Size Image/Picture

High-resolution pictures/images increase the size of your PowerPoint file. That’s why; consider using lower resolution images (at the required quality level).

Open the high-resolution image in Adobe Photoshop or Microsoft Picture Manager or any other image editing program, and save it at a lower resolution.

Remember, like other types of images, you can’t compress 3D models. So, if file size is an issue, insert a picture instead of a 3D model.

4. Reduce the Size of Audio and Video Files

9. Convert Embedded Objects or Charts to Images

Excel charts or other embedded objects can increase the file size of your presentation. However, by converting embedded objects to pictures or images, you can shrink the file size. For this, either ungroup the embedded objects or cut and paste them again into PowerPoint.

Ungrouping Shapes/Objects:

Step 1 – Select the Excel chart or embedded object. 

Step 2 – In the Ribbon, click the Format tab. It will appear as a Drawing Tools Format.

Step 2 – Cut it by pressing Ctrl+X.

Step 3 – In the Ribbon, click the Home tab.

Step 4 – Click the arrow below Paste. From the drop-down menu, choose Paste Special.

Step 5 – Select an image type (such as PNG, JPEG, GIF, etc.). Click OK.

Cutting and Pasting the Object

10. Discard Editing Data for Images

Step 1 – Go to File > Options > Advanced > Image Size and Quality.

Step 2 – Select the box labeled ‘Discard editing data.’ Note that you won’t be able to restore the original image after you edit it.

Ensure that the box labeled ‘Do not compress images in file’ is not selected.

Discard Editing Data

11. Save a Copy of Images with Artistic Effects

PowerPoint retains 2 copies of the image when you apply artistic effects: the original copy and a copy with artistic effects. Images with artistic effects usually remain unaffected even if you compress pictures. You can reduce the file size of such images using the following method:

Step 1 – Right-click the image on which you have applied the artistic effect. A drop-down menu will appear.

Step 2 – Select ‘Save As Picture.’ A dialog box will appear.

Step 3 – Choose the folder where you want to save the image.

Step 4 – Name it and select a file type (PNG or JPG). Click Save.

Step 5 – Delete the image with the artistic effect in the PowerPoint presentation.

Step 6 – Go to Insert > Picture(s).

Step 7 – Go to the location where you have saved the image with the artistic effect. 

Step 8 – Double-click the image.

Use these methods to reduce your PowerPoint presentation size and avoid crashes!
