Chrome 155开始支持JPEG XL图像格式

Chrome 155版本已启用对JPEG XL图像格式的解码支持1。这一新格式相比传统JPEG的压缩效率提升30-50%，同时支持无损压缩、内置HDR功能和无损JPEG转码1。

为了确保安全性，Google使用Rust重新实现了JPEG XL解码器jxl-rs1。该解码器已通过模糊测试和AI代码审查验证，整个实现历史中未发现任何内存安全漏洞1。JPEG XL在Interop 2026项目中被列为2026年的热门提案1。

Google has enabled support for decoding JPEG XL images in Chrome 155, introducing a new image format that offers significant compression improvements over the traditional JPEG standard.1 The JPEG XL format delivers 30 to 50 percent better compression efficiency compared to JPEG while supporting both lossless compression and built-in HDR capabilities.1 Additionally, the format enables lossless JPEG transcoding, allowing seamless conversion between formats.1

To ensure robust security, Google reimplemented the JPEG XL decoder using Rust, a memory-safe programming language, creating the jxl-rs decoder.1 The implementation has undergone extensive verification through fuzzing tests and AI-powered code review, with no memory safety vulnerabilities discovered throughout the entire development history.1 This security-first approach reflects Google's commitment to protecting users while introducing new web technologies.

The addition of JPEG XL support positions Chrome at the forefront of next-generation image formats.1 JPEG XL has been identified as a notable proposal for 2026 within the Interop 2026 project, signaling growing industry recognition of its potential to become a standard web image format.1
