Abstract

JPEG XL is a practical approach focused on scalable web distribution and efficient compression of high-quality images. It provides various benefits compared to existing image formats: 60% size reduction at equivalent subjective quality; fast, parallelizable decoding and encoding configurations; features such as progressive, lossless, animation, and reversible transcoding of existing JPEG with 22% size reduction; support for high-quality applications including wide gamut, higher resolution/bit depth/dynamic range, and visually lossless coding. The JPEG XL architecture is traditional block-transform coding with upgrades to each component.

  1. Google's decision to deprecate JPEG-XL emphasizes the need for browser choice 1 comment

    • The C++ committee makes draft versions of the standard available for free[0], I've heard that often the last draft before a new standard version is published is almost identical to the published version. It would be awesome if someone involved with JPEG-XL could arrange for the…

    • Thanks, I appreciate the corrections and detail. I was mostly going by the committee draft on the arXiv (https://arxiv.org/abs/1908.03565 ), which still mentioned the quantization constraint (J.3) and a "mathematically lossless" mode (annex O) distinct from modular. "Four…

    • A potential future option I only just learned about is JPEG XL (not XR!) which is proposed as a royalty-free successor to the JPEG we know. The draft is at https://arxiv.org/abs/1908.03565 and a little bit about what it has and why is at…
