I've been pretty happy with it, myself. All the base OS libraries support JPEG XL so it's nearly pain-free, excepting lack of web browser support.

Combined with GNU parallel, I did this:

    find -type f -iname \*.jpg -print0 | parallel -0 cjxl --lossless_jpeg=1 {} {.}.jxl 
    find -type f -iname \*.png -print0 | parallel -0 cjxl -d 0 {} {.}.jxl
    find -type f -iname \*.webp -print0 | parallel -0 dwebp -o {.}.png {} \&\& cjxl -d 0 {.}.png {.}.jxl
JPEGs get losslessly recompressed with JPEG XL. PNGs and (lossless) WebPs get converted to lossless JPEG XL.

Nice, I should give this a try and see what it does to my photo library size.

There are a few holdout programs that I think are missing support (Blender3D springs to mind), but I also think in the rare instances where that's a problem I could probably set up a quick shortcut or some hooks to on-the-fly run cjxl and convert back to jpeg/png temporarily for whatever operation I need to do.
