developer.chrome.com 3 min read Editor score 7/10

Chrome 155 adds JPEG XL decoding; the announcement cites 30–50% better compression than JPEG and describes a Rust decoder and performance work. Browser support and decoder safety matter to teams delivering image-heavy web products.

What

Chrome 155 adds JPEG XL decoding with jxl-rs, a pure Rust implementation of the image decoder.

How

Rust’s stabilized target_feature support enables SIMD without unsafe code; jxl_simd provides a SIMD abstraction layer.

Why it matters

The approach combines memory safety for untrusted image data with SIMD performance optimizations and fewer data copies.
