We're excited to announce that Chrome is shipping decoding support for the JPEG XL (.jxl) image format starting from Chrome 155. JPEG XL is a next-generation image format designed to meet the needs of modern web developers and photographers. It offers 30-50% better compression than JPEG, lossless compression, built-in HDR support, lossless JPEG transcoding, and more.
In general, we recommend trying both AVIF and JPEG XL to get the best results. We expect that JPEG XL is most helpful for high-fidelity or lossless compression, especially of photographic images or in cases in which fine-grained progressive decoding is preferred.
In this post, we share why we brought JPEG XL to Chrome, how we used Rust to ensure memory safety first, the extensive performance work that makes it fast, and what the journey tells us about developer feedback and the web standards ecosystem.
