Compress Video (and Audio) Media in PowerPoint

by Avantix Learning Team | Updated April 6, 2021

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

You can compress video (and / or audio) media in a PowerPoint presentation to reduce file size. Since video and audio inserted into a PowerPoint file is embedded or copied into the presentation by default (starting in 2010), video and audio media can increase file size significantly. If you compress media, both video and audio media will be compressed.

When you compress media in PowerPoint, embedded subtitles and alternate audio tracks will be removed in the compression process. If you have trimmed media in PowerPoint, the trimmed portions will also be removed during compression.

Compressing video (and audio) media in PowerPoint

To compress video and audio media in a PowerPoint file:

  1. Save a copy of the presentation that contains the video and / or audio you want to compress. The media files must be embedded, not linked. Online videos (such as YouTube videos) will not be compressed.
  2. Open the copy of the presentation.
  3. Click the File tab in the Ribbon.
  4. Select Info.
  5. In the Media Size and Performance area, select Compress Media. A drop-down menu appears.
  6. Select a video quality. Options in 2019 and 365 include HD choices. Full HD (1080p) will save space while maintaining overall audio and video quality. HD (720p) will save space and the quality will be comparable to media streamed over the Internet. Standard (480p) will save the most space and may be used when sending presentations via email. In 2013 or 2016, the options are slightly different. Presentation Quality will save space and maintain the highest quality. Internet Quality will be comparable to media streamed over the internet. Low Quality is the lowest quality typically suited to email.
  7. Once you select a compression quality, a dialog box appears automatically. PowerPoint will begin the compression process and displays the status as well as the amount of space saved when completed. This process may take a while depending on media size and number of video and or audio files to compress.
  8. Click Close when compression is complete.

You will not be able to access Compress Media unless embedded media has been inserted into the presentation.

In PowerPoint 2019 or 365, the following drop-down menu appears when you click Compress Media:

In PowerPoint 2013 and 2016, the following drop-down menu appears when you click Compress Media:

If you have inserted a video on a PowerPoint slide, you can display a custom thumbnail (or Poster Frame) for the video during a slide show. The thumbnail will display when you run a PowerPoint slide show and disappears when you start the video. For most videos, the thumbnail that displays is the first frame of the video clip. You can use the Poster Frame command to display a different frame in the video clip or a picture from another source as a thumbnail. A picture thumbnail could be either an image or an icon.

How to Add Audio in PowerPoint Presentations

You can add audio in PowerPoint from a file on your PC or from a shared drive. Audio is played during a slide show and you can insert music, sound clips, or voice recordings. Since audio files are copied into PowerPoint presentations by default, they can increase file size and may need to be compressed. To play audio, your computer must be equipped with a sound card and speakers.
