Let’s see what browsers/apps actually support animated JPEG-XL files! And in case it isn’t working for you, here is a still shot from this animation, in a widely-supported format:

BVo9MLVuZHYMEWA.webp

Also, I could not find a reputable source to explain exactly what the X in JPEG-XL actually stands for, so I just went with “extensible”, a la XML.

    It doesn’t work in Chromium at all, only in forks that hack it back in like Thorium.

    Firefox needs a flag enabled in about:config, yes.

    …And yeah. Realistically, a low framerate AV1 (or AVC) webm is more optimal for this, better supported, and will perform better on a lot of hardware. TBH JXL should drop the animation stuff and focus on static images (which it’s incredible at) and HDR support.

      Yes Google has really been the biggest one fighting against jxl. Mozilla has flirted with it a lot. Mostly dropping it because of the perceived peer pressure.

        Yeah, it’s ridiculous.

        All the AI stuff they’re shipping in Chrome, and the concern with JXL is security/attack surface? That’s a total lie. It’s so much better than AVIF for certain niches, and it’s already supported by Apple.
