What is GIF?
GIF is the classic format for short animations and memes. It plays automatically and loops in every browser and chat app, but it is limited to 256 colours per frame and stores video very inefficiently, so animated GIFs are often many times larger than the same clip as MP4.
What is WebM?
WebM is an open, royalty-free video format backed by Google and designed for the web. It uses VP8, VP9 or AV1 video with Opus or Vorbis audio, plays natively in modern browsers and keeps files small, though some editors and Apple devices handle it poorly.
Tips for converting GIF to WebM
- A WebM of the same animation is usually far smaller than the GIF, and it loops if the player is set to.
- The video will have no sound track, because GIFs never carry audio.
- Transparent areas of a GIF are filled with a solid colour, since common video formats do not keep transparency.
- Check that the site or app you want to post it on accepts WebM uploads before converting many files.
