Frequently asked questions

How much smaller is JPEG XL?

Commonly several times smaller than the same GIF, because JXL has modern entropy coding and is not stuck with a 256-color palette per frame.

Can browsers display JXL?

Safari does. Chrome and Firefox need a flag or do not support it at all, so JXL is a storage and archive format today rather than something to put on a page.

Is the conversion lossless?

The color already lost to GIF quantisation is not recovered, but the encode preserves what the GIF holds rather than throwing more away.

What should I use for the web instead?

MP4 for anything long, or WebP if you need a single animated image file that every current browser will render.
