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.JPEG XL covers nearly every use case for images, even replacing GIFs with it's animation support.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.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.Without a doubt 5 years now JPEG XL will become like Opus and set the standard for next generation image formats.
