I had assumed that JPEG XL was for JPEGs that are Xtra Large, since that's what XL means on clothing and pretty much everywhere else. But apparently not:
> 'The etymology of the name "XL" is as follows: JPEG has called all its new standards since j2k something that starts with an X: XR, XT, XS (S for speed, since it is very fast and ultra-low-latency), and now XL. The L is supposed to mean Long term, since the goal is to make something that can replace the legacy JPEG and last as long as it did.'[1]

What most people don't know is that JPEG XL can be used to crush JPEG files by 15% to 25% without any single quality loss. And the resulting .jxl file can be used to then reproduce the original .jpg file bit-for-bit. People can test this at the CLI for themselves.
- cubefox 1mo agoJPEG XL is also "extra large" in the sense that it covers many features of more specialized image formats. They tried to come up with a pretty universal solution. > It supports wide colour gamut as well as high dynamic range and high bit depth images. JPEG XL further includes features such as animation, alpha channels, layers, thumbnails, lossless and progressive coding (...) https://jpeg.org/jpegxl/ https://jpeg.org/jpegxl/ More features are described in this nice overview article: https://arxiv.org/pdf/2506.05987 https://arxiv.org/pdf/2506.05987

- yboris 1mo agoYou can refer to JPEG XL as its file extension `jxl` pronounced "jixel" ;)
