A new comparison testing JPEG XL now that it has landed in all major browsers found that AVIF produces smaller files than JPEG XL for lossy photos, screenshots, illustrations and transparent images in the vast majority of cases. The gap ranges from about 6-25% for photos at maximum effort to 30-90% for screenshots and illustrations, with AVIF also decoding faster. The analysis compared two JPEG XL encoders, libjxl and jixel, noting jixel usually makes smaller files except when images have detailed transparency.

Mozilla has released Firefox 158, which turns on support for the JPEG-XL image format by default for users. Previously, JPEG-XL required users to manually enable an experimental flag to view such images in the browser.

Google has launched Chrome 155, incorporating support for decoding JPEG XL images, a format that improves compression efficiency and supports advanced features like HDR and animation. The update aims to enhance web performance and visual quality, encouraging adoption among developers and content creators. Chrome's integration of JPEG XL marks a step toward a richer, faster, and safer web experience.

Google says Chrome 155 will support decoding JPEG XL (.jxl) images, a format offering 30-50% better compression than JPEG, lossless compression, HDR support, and lossless JPEG transcoding. The decoder was rebuilt in Rust, via the jxl-rs project, to improve memory safety while matching the performance of existing C++ implementations.

Mozilla's Firefox 156 release improves large JPEG handling by using libjpeg-turbo's IDCT scaling during decoding instead of loading full-size images first, cutting memory use up to 20 times and doubling decode speed. The update also makes the built-in PDF.js viewer start up to 45% faster by loading its background worker earlier, and expands sponsored address bar suggestions to France, Germany and Italy. Firefox 157, due in about two weeks, is expected to add support for the JPEG XL image format.

A compression engineer revisits JPEG XL's standing on the Web, noting that despite its technical strengths over JPEG and WebP, Chrome dropped support in 2023. He points out that a new Rust-based JPEG XL decoder has since appeared in Firefox and parts of Chrome, partly to avoid repeating a security flaw once found in WebP, but argues this alone doesn't settle whether JPEG XL deserves broad Web adoption.

Mozilla announced it will turn on JPEG XL decoding by default across all Firefox platforms starting with version 157, using its Rust-based jxl-rs decoder. The feature has been available as an opt-in Labs setting since Firefox 152 and behind a hidden preference since earlier releases, and now gains multithreaded decoding to match performance with Safari's implementation.
