About the JPEG XL format
JPEG XL
JPEG XL (ISO/IEC 18181) supports lossy and lossless compression, transparency, animation, HDR and progressive loading. A distinctive feature is lossless recompression of ordinary JPG files, which become about 20% smaller.
Safari opens JPEG XL since version 17, Chrome since version 155 and Firefox since version 158 (both released in October 2026); Edge and other browsers don't have it enabled yet. Many programs, older browsers and website upload forms don't accept it, so for sharing it is safer to convert JPEG XL to JPG or PNG.
Best for archiving photos and high-quality images with a small file size.
