Move to Jpeg XL
under review

As recent upgrades on the go are focusing on getting a better performance, Jpeg XL would make better quality smaller size files (quicker to load). It outperforms all other image formats in terms of image quality and compression ratio (in both the lossless and lossy modes), and many other factors.
Here is a good and easy to understand comparison too to some other formats: https://beebom.com/what-is-jpeg-xl/

I made this comment on the 2k texture feature but it's more relevant here.
Webp is fully patent-free and free software. Whereas, we know that Microsoft just grabbed a patent on the core algorithm in JPEG-XL: https://www.theregister.com/2022/02/17/microsoft_ans_patent/
Also, google refused to support JPEG-XL in Chrome, which means most people can't view it without special software and/or safari.
Gimp has poor support for JPEG-XL (only 8-bit lossless). And, Krita has a problem where it flattens the layers when anims are made with JPEG-XL, etc. Whereas Krita and Gimp fully support all the features in WebP, as well as all major browsers as it is a part of the standard.
I like JPEG-XL but it didn't get implemented properly across the board again, unironically the same problem JPEG-2000 had which LL also bet on. Broad support and tools which can edit and load the format properly is important for a platform that caters to creators where people need to be able to work with the images.
Also, Webp is slightly faster on the decoder and 2x to 10x times faster encoding than JPEG-XL. However, JPEG-XL is a good replacement for AVIF as the latter is quite a bit slower. Having said all that, though, I really like JPEG-XL's jpg recompression. But, I think the rest of the arguments weigh against it.
SL Feedback
Merged in a post from Philbert Susa:
Title: Add modern image formats like webp for snapshots
Details: As flexible as they are, JPEG is getting long on the tooth on quality and compression amount. WebP and jpeg XL offer much better ratios, especially as we are taking larger and larger snapshots. WebP's lossless compression makes a good compliment to PNG as well.

In addition, truncated JPEG XL files are still displayable, just in a smaller resolution. So even if transfer is interrupted, the viewer can already start showing a texture albeit not at full resolution yet.

Question because I'm on mobile. What is the file extension for these? It's the first I've heard of it and my limited knowledge, possibly corrupted is that png images were the best.
