Reduce a document’s file size in Pages on Mac
If your document includes image, audio, or video files, you can reduce its file size to make it easier to send, post, or share.
If you don’t want to permanently change your original document, you can save a copy of it with a smaller file size instead.
Choose File > Reduce File Size (from the File menu at the top of the screen).
Select the adjustments you want to make:
Scale down large images: Images are scaled to the resolution used in the document while preserving visual quality. For example, if you added a photo to your document and resized it to be smaller, selecting this option removes the unused image data.
Note: Whether or not you select this checkbox, if an image is in a format that can’t be viewed on iPhone or iPad, it’s automatically converted to a format that can.
Remove trimmed parts of movies and audio: If you trimmed the start or end of movies or audio (using the controls in the Format sidebar), the trimmed portions are deleted.
Most compatible (H.264): Movies in your document are converted to H.264 format, which plays on most iOS and iPadOS devices and Mac computers.
High efficiency (HEVC): This format option appears only if you’re using macOS 10.13 or later and your Mac supports hardware HEVC encoding. Movies in HEVC format have the best quality at the smallest file size, but they can be played only on devices with iOS 11, iPadOS 13, or later, and Mac computers with macOS 10.13 or later.
If you’re using macOS 10.13 or later and Pages 7.0 or later and you select this format, you can later add HEVC files to the reduced-size document or copy. For more information about HEVC, see this Apple Support article.
Note: H.264 and HEVC don’t support alpha channels, so transparency is converted to a black background.
Preserve original format: This option retains the current movie formats. In this case, any movies in formats incompatible with iOS or iPadOS aren’t optimized and therefore don’t play on iOS or iPadOS devices.
Movie Quality: Set the maximum resolution for movies. Movies with a resolution smaller than the maximum aren’t scaled up.

Note: It’s possible to choose a combination of options that makes the file size larger.
