Frequently asked questions

Why is AVIF so much smaller?

It uses AV1, a video codec, so it stores the difference between frames. GIF and APNG both write whole frames, which is why they are an order of magnitude larger.

Does it play in browsers?

Chrome, Firefox and Safari all render animated AVIF. Outside the browser support is thin, so it is a web format rather than a share-anywhere one.

Why does encoding take a while?

AV1 encoding is genuinely expensive, and this runs in your browser rather than on a server. Shorter ranges and lower frame rates finish considerably faster.

When should I just use MP4?

For anything with sound, or longer than a few seconds. AVIF earns its place for short silent loops that need to sit in an img tag.
