Jpeg XL is a new-ish modern image format (ISO standard fully finalized in 2022), with compression rivaling or surpassing current formats. Reference encoder/decoder is libjxl in C++, and decoder jxl-rs in Rust.
It is royalty-free, a free and open standard.

Awareness and usage of it is about to increase in a big way, as support will be enabled by default in Firefox and Chromium within a month. And it is already supported by a wide variety of image-related programs such as Photoshop and Krita etc, and has been announced to be included in the PDF spec in the future.

With support for it I could, losslessly, cut the total filesize of my slideshow wallpaper library that's currently .pngs in half.

We've added this to our feature request list, thanks!

The official extension is for Win11 and I am on Win10 so I can't install that, but it is none the less working! Thank you!
I do have a 3rd-party jxl thumbnails thing installed that I am guessing might do similar hooks/support as the official one does: https://github.com/selpats/jxl-winthumb

I did get one issue that might not be directly related, applying wallpaper settings have gotten far slower this version.
Downgraded to 12.1.1 to compare, only using png images to be consistent across the versions, and it goes from under 10 seconds in 12.1.1 to about a minute and half in 12.2 beta 2.
The reason seems to be added overhead per image loaded. I have currently 134 images for my slideshow, and if I instead use single+single instead of single+slideshow on my two monitors it loads in <10 seconds, so the raw number of images seems to be the culprit where it wasn't an issue before.
