JPEG XL is a next generation image format. One of its features is byte-wise lossless JPEG image repacking. On average, an encoded image is 22% smaller. This encoding could be used as an HTTP "Content-Encoding" specifically for JPEG image transfer (such content is considered non-compressible for general-purpose formats like Brotli and Gzip). The proposed encoding name: 'jxl'


Losslessly reduces Internet traffic. Makes the Internet faster.
