I mean to be fair writing is on the wall some when a superior format like jpegxl exists but is arbitrarily held back purely because Google's Chromium team wants to push the format they made over the format another Google team worked on.

Superior in file size, image quality, computation required for equivalent quality encoding, no arbitrary resolution caps, progressive decoding which also lets you create 'thumbnails' or resizes by just cutting the byte stream, while also having features to help legacy jpeg files benefit from newer compression losslessly. The only benchmark avif bests at is abhorrently low quality levels that no one genuinely uses.

My theory was that strategically, Google wants to make AVIF ubiquitous to promote adoption of decoders for it in mobile devices; AVIF losing to JXL is a "whatever" on Google's part, but AV1 losing to H265 means another decade of royalties for YouTube.

I'm a big fan of JPEG XL, but even its most dedicated fans have given up the argument that it is the best for compression efficiency. AVIF's generational leap took place in August 2024 with Tune Still Picture in SVT-AV1-PSY, so much so that Google integrated it into their own encoder and has done very impressive work optimizing it further for the human visual system. JPEG XL's strongest quality is its featureset; lossless JPEG recompression, for example, is really incredible

I will need to double check. I think even after PSY JPEGXL still excel at BPP 1.0+, and that is 85% of all images served according to Chrome. AVIF is still winning on below BPP 0.8.
Anyway we only have to wait a few more months to see AV2. Let's hope finally they have everything ready.

All of that is pretty moot and not something I care about much as long as it's better than JPEG. Let everyone support AVIF and stop this perpetual bikeshedding.

AVIF already works in all browsers, all sites should support it.

Which format are you saying the Chromium team made and wants to push in favor of jxl?

  Which is superseded by AVIF anyway.

  Not for lossless; webp is a fantastic replacement for PNG there. Not so much with AVIF, it's sometimes even heavier than PNG.

  How will AV2 based AVIF compare to PNG?
