FYI, if you use #Firefox you can now enable #JPEGXL support to try it out (without having to fiddle around with any tricky settings):

Just go to Settings > Firefox Labs > and enable the “Media: JPEG XL” checkbox.

It’s good to see that it’s another step closer to being enabled by default!

#Safari / #WebKit has had support for about three years (but doesn’t yet implement progressive loading), and #Chrome has it behind a feature flag, but not much has happened recently. Getting there, slowly!
