Would be very nice to have both! It's about time we got better image formats.

That said, unfortunately AVIF is not a substitute for JPEG XL...

1. AVIF has an order of magnitude slower saving / encoding speed vs JPEG XL.

2. AVIF in "lossless" mode tends to be bigger than PNG- and it isn't truly lossless, just best effort (based on the AV1 video format).

3. JPEG XL supports orders of magnitude higher resolution, bit depth, and is an actual replacement for lossless PNG.

Yes. One can barely argue AVIF is better than JPEG XL on the Web.

For authoring, JPEG XL win hands down.

I didn't intend to create another opportunity for jpeg-xl partisanship, but well, it happened.

One can very persuasively argue that AVIF is better on the web; for 99,999% cases used in the wild it will be better. Yes, some marginal cases are better handled by another formats, it is nothing unheard of.

For authoring, .psd, .afphoto or whatever is the native format of the used app will be used.

JPEG XL has better quality than AVIF at BPP 1.0+ and that is 85% of all images on the web according to Google Chrome Browser Stats.
