What's better? Avif or jepg xl?

[โ€“] Knusper@feddit.de 4 points 1 year ago

Honestly, I have no idea. It sounds like AVIF also has wide industry support and is generally quite proficient.

But JPEG XL likely wouldn't have been created, if AVIF was perfect. Wikipedia says:

The [JPEG XL] standard is expected to outperform the still image compression performance shown by HEIC, AVIF, WebP, and JPEG 2000. It also provides efficient lossless recompression options for images in the traditional/legacy JPEG format.

I'm guessing, AVIF was created, because it basically already existed. It's using the AV1 video codec to encode a single-frame video and that just happened to be better than the competition.
JPEG XL being more focused on those still images could obviously still outperform it. I guess, we'll have to see.

For right now, though, yeah, JPEG XL might still be too young and AVIF therefore the better choice.
