I heard about this recently and decided to look into it. Seems neat. When I convert my existing .jpeg images to .jxl, they look identical, but take up only ~60% the space. Windows file explorer and paint dont support it however, but ImageGlass does. Considering converting all my images to .jxl to save on storage space (esp. cloud storage). Thoughts?
Strangely, I enabled it a year ago and jpegxl.info is still displaying that my navigator does not support jpegxl
