Shipping JPEG XL in Chrome

Google Chrome is shipping decoding support for JPEG XL (.jxl) image format starting with Chrome 155, offering 30-50% better compression than JPEG along with lossless compression and HDR support. The implementation prioritizes security by using a pure Rust decoder (jxl-rs) to eliminate memory vulnerabilities common in traditional C++ image decoders, while maintaining competitive performance through optimized SIMD operations. Chrome recommends using JPEG XL alongside AVIF formats for optimal results, particularly for high-fidelity photographic images and lossless compression needs.
