A destination, instead of one setting
Optimize combines operations for a particular destination: format conversion, resizing and supported metadata removal. Unlike Compress, it may change the file format and dimensions.
All processing is local. A preset name such as Email or Discord does not send or upload the file anywhere.
What each preset chooses
- For web: WebP images or VP9 WebM video, with a maximum height of 1440 px.
- For Discord: WebP images or H.264 MP4 video, up to 1080 px high, with a 10 MB preset target.
- For email: JPEG images, or WebP when transparency needs to be retained, and MP4 video. Up to 1080 px high with a 10 MB target.
- For storage: AVIF images or AV1 WebM video, up to 2160 px high. This can take longer to encode.
When to use it
Choose Optimize when the destination matters more than retaining the original format. Choose Compress to keep the format and dimensions, or Convert when you only need another format.
A size target is not a guarantee for every source file. If it cannot be reached within the quality policy, use a less restrictive target or a smaller explicit resize.
