What is JPEG XL?
JPEG XL is a next-generation image codec being in the process of being standardized by the JPEG Committee. It separates itself from other newer formats like WebP, AVIF, and HEIC as it is not based on any video codec like they are. This gives it an advantage as it has been specifically made to display images and offers much better quality and smaller file sizes than any other codec.
