Sadly no. Most browsers don't render static JXL by default yet. Let alone animated. I wish they would. Though for most things regular video transport streams will usually be as good or better. Honestly at this point animated image formats really are kind of a niche and not necessarily super useful at this point. Apng for instance when it was created nearly 20 years ago made some sense. Today now that it's finally getting supported it doesn't make as much sense.
