    This is the first I’m hearing of jpeg-xl what are some of its advantages? I thought everything was moving to av1.

      https://avif.io/blog/comparisons/avif-vs-jpegxl/

      IMO the most important points:

      • JXL allows for progressive rendering (e.g. it can only los an image partially)
      • JXL is faster
      • JXL has better compression on higher quality levels
      • AVIF is better for low fidelity images

      JXL was made for images only, whereas AVIF comes from Video frames. Technically JXL is superior in most categories. I can’t tell for the license what is better.

        Also: JPEG can be losslessly converted to JXL. Typically converting from one lossy format to another lossy format decreases quality. But in case of JXL, you can take old JPEGs and make them smaller without losing information.

        That’s a really informative graph. I just converted a bunch of images from png to jpg. I’ll try to convert to this tomorrow. Im curious about the size difference.

          Great to hear and good luck! Another good thing to know is, that you can always convert back and forth between JPEG and JPEG XL without any data loss, I love that functionality!
