About this tag
The jpeg xl tag on WindowsForum.com collects discussion of JPEG XL image support in browsers and on Windows. Recent coverage centers on Chrome 155 enabling JPEG XL decoding by default through the memory-safe jxl-rs decoder written in Rust, and on correcting claims about which Firefox version shipped comparable support.

Expect thread-level analysis of browser version timelines rather than general image-format tutorials.
