JPEG XL
A next-generation image format standard offering high compression ratios, lossless transcoding, and progressive decoding. It supports lossless recompression of existing JPEG files and is suited for wide color gamut and HDR use cases.
Timeline (last 90 days)
JPEG XL supports lossless recompression of existing JPEG files, saving an average of about 20% in file size, and the files can be fully restored to the original JPEG.
JPEG XL adopts a hierarchical encoding structure based on wavelet transforms, allowing the decoder to first render a low-resolution preview with a very small amount of data and progressively refine the image as more data arrives.
JPEG XL supports wide color gamut, high dynamic range (HDR), and a unified encoding architecture for both lossless and lossy modes.
AVIF's progressive decoding support is relatively limited, resulting in a less smooth experience than JPEG XL in large image loading scenarios.
Google announced the removal of JPEG XL support from Chromium in 2022 in the form of an "Intent to Unship".
Google's official reason for removing JPEG XL support was that the compression efficiency improvement was insufficient to justify maintenance costs, and that developer community interest in the format was limited.
The Safari browser provides support for JPEG XL.
An article titled "The case against JPEG XL" sparked a debate on Hacker News about the fate of the format.
The adoption of image formats faces a "chicken-and-egg" dilemma: without browser support, content providers are unwilling to adopt them, and without content adoption, browsers lack the motivation to provide support.
