Firefox to ship JPEG XL via Rust decoder; cross-browser support expected this year
↗
Mozilla announced intent to ship JPEG XL in Firefox using a Rust-based decoder built by Google Research, with Chrome and Safari also adding support.
JPEG XL will soon have cross-browser support, giving developers a second modern format choice alongside AVIF. The format's strengths in lossless compression and progressive rendering complement AVIF's advantage at web-quality file sizes, so the decision between them becomes a content-specific tradeoff rather than a compatibility gamble.

Mozilla will ship JPEG XL using jxl-rs, a Rust decoder built by Google Research to reduce the attack surface of the original 100,000-line C++ implementation.
Chrome intends to ship JPEG XL and Safari already has partial implementation, meaning cross-browser support is expected before the end of the year.
JPEG XL outperforms AVIF for lossless compression and progressive rendering, while AVIF generally produces smaller files at web-quality settings.
