Will animated JPEG XL be supported? I like to make animated images and dislike GIF for obvious reasons, but WebP is not a perfect replacement for philosophical reasons. I am eager for more programs to support JPEG XL so I can use that format for the animations that I create.

But in my experience with WebP, some programs that claim to support that format only support static WebP images. When they encounter an animated WebP, some programs only render the first frame of that animation. Due to that experience, I am hesitant to assume that animated JPEG XL images will work just because static ones do.

If you want to test, here is an animated JPEG XL I made a while ago: https://files.catbox.moe/80ottu.jxl
