JXL is based.
I took my existing JPEG file, compressed it using JXL, 15% smaller.
Then I decompressed it again into JPEG. The file was bit-for-bit identical to the original file (same hash). Blew my mind!
Directly using JXL is even better of course.
So it's called xlarge... And it makes files smaller.
Why.
The same amount of JXL gives you more image than JPEG? Also, it supports ridiculous resolutions (terapixel).
Google's involvement should always raise concerns but I guess it's good Mozilla is trying to improve stuff.
Please let this happen!
I have a nagging doubt; jpeg-xl has a very extensive feature set (text overlays, etc). meanwhile, tech/media consortia want a basic spec for AV1 + OPUS on chip and push that to all media capable devices. we can expect av1, avif and opus to be ubiquitous in a few years. So i think they will prioritise AVIF.
I did some reading in AV1 and it's derivative formats - are they any more accessible to Linux than HEVC/H265? Fedora IIRC removed support for them and a few other codecs out of the box over some patent concerns or something.
Google's involvement is weird, not for any conspiracy reasons but because the chromium team previously cancelled JPEG-XL.

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
