GoKawiilChrome 155 adds native JPEG XL decoding support
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.
GoKawiil's interpretation of the reporting above, not reported fact.
Adding JPEG XL alongside AVIF gives web developers more options for balancing compression quality, file size and decoding speed, particularly for photographic or high-fidelity images. The move to a Rust-based decoder also reflects a broader industry push to reduce memory-safety vulnerabilities in browser code that handles untrusted data, which Google frames as a major attack surface.
- Chrome 155 adds decoding support for the JPEG XL (.jxl) image format.
- JPEG XL offers better compression, lossless options, and HDR support compared to JPEG.
- Google reimplemented the decoder in Rust (jxl-rs) to improve memory safety without sacrificing speed.
