Chrome adds JPEG XL image decoding starting in Chrome 155

Image: Hacker News (100+ points)

Why it matters for readers: It means web images could get smaller and look better in Chrome, with fewer crashes from unsafe decoders.

  • Chrome 155 adds native decoding support for the JPEG XL (.jxl) image format.1
  • JPEG XL offers roughly 30–50% better compression than JPEG, plus lossless modes, HDR support, and progressive decoding options.1
  • The decoder in Chrome is implemented in Rust (jxl-rs) to prioritise memory safety.1
  • Google recommends trying both AVIF and JPEG XL, with JPEG XL suited to high‑fidelity or lossless photographic use cases.1
