> though AVIF is currently ahead of JPEG-XL in browser support.
It certainly looks like AVIF is ahead because it has landed in and Firefox and Chrome, but it's blocked in Safari by a required OS change[0] (iOS/macOS support if I understand the comment correctly?). Additionally, there's no implementation in Edge (even though it's chromium)[1]. Sorry, I wish I had more details but I'm not sure where to look to find a status update on that.
Meanwhile, JPEG-XL has support behind a feature in every major browser except Safari[2]. As you and others have noted, there seems to be a lot of buzz and excitement around JPEG-XL throughout the ecosystem. The webkit folks seem to be making an effort to get the ball rolling[3]. I might be misinterpreting something but it all looks very encouraging at any rate. It almost seems like it might gain wide support in Firefox and Chromium (Chrome & Edge) around the same time with Webkit following (hopefully) closely thereafter. Heck, I don't see why Webkit doesn't just abandon AVIF and focus on rolling out JPEG-XL.
