Explainer No information provided Specification https://www.iso.org/standard/85066.html Summary Adds support for decoding JPEG XL (image/jxl) images in Blink using jxl-rs, a memory-safe pure Rust decoder (https://github.com/libjxl/jxl-rs). JPEG XL is a modern image format standardized as ISO/IEC 18181 that offers progressive decoding for improved perceived loading performance, support for wide color gamut, HDR, and high bit depth, and support for animation. Blink component Internals>Images>Codecs>JPEG XL Web Feature ID jpegxl Motivation (see Summary) Initial public proposal No information provided TAG review https://github.com/w3ctag/design-reviews/issues/633 TAG review status Issues addressed Goals for experimentation Risks Interoperability and Compatibility No special risks. Note that the C++ and the Rust version are both tested against the same conformance test corpus. Gecko: Shipped/Shipping also migrating to rust version WebKit: Shipped/Shipping WebKit currently uses the C++ decoder. Web developers: Strongly positive Other signals: WebView application risks Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications? New feature, no special risk Debuggability No information provided Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)? Yes Is this feature fully tested by web-platform-tests? Yes https://wpt.fyi/results/jpegxl?label=experimental&label=master&aligned There is extensive conformance testing outside of WPT too. WPTs show failures because the flag is disabled in wpt runs. https://wpt.fyi/results/jpegxl?sha=3d06a34791fc33532baffe64e5c48c450cb1a1b9 shows a run with the flag enabled, which has two failures. The icc-uncommon-profile-reftest.html failure is a small difference visually, currently investigating. The cmyk-basic-conversion-reftest.html failure is being fixed in https://chromium-review.git.corp.google.com/c/chromium/src/+/8275513 Flag name on about://flags enable-jxl-image-format Finch feature name JXLImageFormat Rollout plan Will ship enabled for all users Requires code in //chrome? False Availability expectation Feature is available on Web Platform Baseline within 12 months of launch in Chrome. Adoption expectation Feature is considered a best practice for some use case within 12 months of reaching Web Platform baseline. Adoption plan Multiple players on the web have expressed interest in deploying JPEG XL images, including at least Cloudinary and Shopify, as well as multiple web developers during the Interop process. Non-OSS dependencies Does the feature depend on any code or APIs outside the Chromium open source repository and its open-source dependencies to function? No. Estimated milestones No milestones specified Anticipated spec changes Open questions about a feature may be a source of future web compat or interop issues. Please list open issues (eg links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (eg, changing to naming or structure of the API in a non-backward-compatible way).
