How to do it

the tool · the steps · what to avoid
  1. 1

    Open your PDF in Adobe Acrobat.

  2. 2

    Select the embedded media (such as video or audio) you want to optimize.

  3. 3

    Right-click the media and choose Edit or the equivalent option to open the media properties dialog.

  4. 4

    Note the current format and encoding of the media.

  5. 5

    Remove the existing media from the PDF.

  6. 6

    Use a media editing tool (such as Adobe Media Encoder) to re-encode your media to a more efficient format (e.g., H.264 for video, AAC for audio) and adjust compression settings to reduce file size while maintaining acceptable quality.

    Best practiceFor best compatibility, use MP4 (H.264) for video and MP3 or AAC for audio before embedding.

  7. 7

    Save the optimized media file to your computer.

  8. 8

    In Acrobat, go to the location where the media was removed and use the Rich Media or Multimedia tool to re-embed the optimized media file into the PDF.

    NoteAcrobat supports embedding video in MP4 (H.264) and audio in MP3 formats for maximum compatibility.

  9. 9

    Adjust playback and display settings as needed in the media properties dialog.

  10. 10

    Save your PDF to apply the changes.

Optimizing embedded media before adding it to your PDF can greatly reduce file size and ensure it plays correctly on most devices.

This runs in the Acrobat app - there is no separate API for this task.

FAQ

about this task

You can use Adobe Acrobat's tools to compress images and change video or audio formats to smaller ones, which helps reduce the overall PDF file size.

Optimizing means making the pictures, videos, or sounds inside your PDF use less space and making sure they work well on most devices and programs.

If your media is not compatible, some people may not be able to see or hear it when they open your PDF, especially on different computers or phones.

Yes, you can often shrink file size by choosing the right formats and compression settings, so your media still looks and sounds good while using less space.

Use common formats like JPEG for images and MP4 for videos, and test your PDF on different devices to make sure everything plays or shows up correctly.
