    A while ago Google removed JPEG XL support from Chrome. But recently Mozilla said their are considering a Rust implementation from the JPEG-XL team at Google Research, so maybe there's still hope for Chrome to start supporting it again. From my personal tests, it's my favorite new image format.

    Here's a relevant video from 2kliksphilip that talks about how JPEG XL stacks up against competition, and how it's faring in the fight against AVIF and WEBP.

      Hey I think you missed the last letter (Y) in that link.

    So it's smaller than competitors, lossless, and uses magic to make images appear faster?

    JPEG XL’s state-of-the-art progressive encoding and decoding supports saliency progression — face detail sent first, background detail later; and reordering — middle data sent first and the rest later. You’ll see an image sooner than with other formats.

    Plus, I'll be honest, I don't see any difference in image quality, even when it seems it may be trying to show that there is a difference? So what's the downside?

      Encoding can be slower.

        Is this compared to standard JPEG? Wikipedia says it "is about as fast as old JPEG."

          Compared to WebP & AVIF, I believe. It's not a huge downside though.

            I thought WebP and AVIF both (differingly distant) hailed from WebM, which is notorious for its slow encoding. AV1 even more so. Is it a difference of expectations for image vs video?

            The linked page seems to imply that JPEG XL is faster, although I don't understand the graph of MP/sec vs bits/pixel.
