What’s the best lossless image format?
JPEG XL is the standard to beat them all. Like how Opus became the definitive codec for lossy compression for the web.<p>JPEG XL covers nearly every use case for images, even replacing GIFs with it's animation support.<p>Existing JPEGs can also be re-encoded losslessly into JPEG XL format/data structure and get significant file size savings. This backwards compatiability is very important in transitioning to web to JPEG XL seamlessly.<p>What I'm most excited about for JPEG XL is progressive decoding, I had been following the FLIF project for a while and was disappointed with it's lack of adoption. But it's future found itself in JPEG XL.<p>Without a doubt 5 years now JPEG XL will become like Opus and set the standard for next generation image formats.
