JPEG XL aka .jxl is now supported by Firefox 152 and Chrome since 145 (behind a flag though on both).

JXL is the best image format we have - supports lossy and lossless compression, HDR, and much more!

The format supports HDR, but most apps using it don’t.

I’ve given up trying to use JXL in the Apple ecosystems for exchanging HDR images for this reason.

Speaking out of genuine curiosity here, but what kinds of photos are you taking that require HDR?
