JPEG XL is a modern image format intended to address many of the problems associated with legacy formats. Unlike other video-first formats like AVIF, the JPEG XL compression algorithm was built for still images from the start. Given the file savings, compression speed, and features, you'll be seeing a lot more of it on the web in the near future.

This tool converts images losslessly, and due to JPEGXL's unique lossless JPEG recompression, you're able to revert that conversion to get the exact, original JPEG back. Bit for bit. Pretty cool.
