Specification

https://arxiv.org/abs/1908.03565

Summary

JPEG XL is a new royalty-free image codec targeting the image quality as found on the web, providing about ~60% size savings when compared to original JPEG at the same perceptual quality, while supporting modern features like HDR, animation, alpha channel, lossless JPEG recompression, lossless and progressive modes. It is based on Google's PIK and Cloudinary's FUIF, and is in the final steps of standardization with ISO. This feature enables image/jxl decoding support in the blink renderer
