Context: Even though Chromium has native support for AVIF, a very nice image format, Microsoft goes out of their way to remove it from Edge, which is a chromium fork. Jpeg XL (JXL) (not to be confused with Jpeg (JPG) or Jpeg 2000 (jpg2k) ) is another nice image format, which, IIRC, is only supported in Firefox.
Png because it’s lossless and pretty universal. Svg is pretty cool because it’s vectorized but it’s also a pain to make good svg.
Still waiting for animated PNG. It would make it the perfect universal compressed image format.
Animated PNG actually does exist but it has poor support coverage.
I remember using it to make whatsapp animated stickers
All major browsers (98% of all users) have supported APNG since at least 2020
Firefox: 2008.
Safari: 2014.
Chrome: 2017.
Edge: 2020.

I believe the photo app in Win 10 (and maybe 11) still doesn’t support it but that shouldn’t hinder web devs.
I didn’t even know that was a think. That would be hella cool.
