Compress your media files

You can improve playback performance and save disk space by compressing your media files.

  1. Open the presentation that contains the audio or video files.

  2. On the File tab, click Info, and then in the Media Size and Performance section, click Compress Media*.

    Click Compress Media

  3. To specify the quality of the video, which in turn, determines the size of the video, select one of the following:

    • Presentation Quality     Save space while maintaining overall audio and video quality.

    • Internet Quality     Quality will be comparable to media which is streamed over the Internet.

    • Low Quality     Use when space is limited, such as when you are sending presentations via e-mail.

Important:  Certain older video file formats may not compress or export properly in Office on a Windows RT PC. Instead, use modern media formats such as H.264 and Advanced Audio Coding (AAC), which PowerPoint 2013 RT supports. Want to know what version of Office you’re using?

* Embedded subtitles and alternate audio tracks will be lost in this compression process.
