Comment on PNG has been updated for the first time in 22 years — new spec supports HDR and animation

  Some parts of the open source world probably still desperately try to make JXL happen. This is understandable, considering its potential. Shame this wouldn’t work.

    Why are they trying to make it happen, and why it no work? Is JXL better than PNG? Maybe I need to do some research to better learn the difference

      JXL can do lossy images (like JPEG) and lossless ones (like PNG), and on average it’ll produce smaller file sizes than both (While beating JPEG quality wise). The killer feature is that it can do lossless recompression of existing JPEG files and shave off about 20% of the file size, and it’s reversible so you can turn those JXL files back into JPEG images for existing software.

      The downside is that it was created by Google Research (among others), but the Chrome team made AVIF instead and decided that’s what they’d support and nothing else.

      At least Safari supports it.

        lossless recompression of existing JPEG Uh… how does it make a JPEG lossless? Or is it lossless in that it makes a JXL out of a JPEG without affecting the original JPEG quality (i.e. no further loss beyond JPEG’s)?

        Being able to turn JPEGs into JXLs and JXLs back to JPEGs is cool, though

        What’s with the AVIF thing? Yet another I am unfamiliar with (all I know about image formats is JPG = worse quality, PNG = better quality, GIF = animated (and something WebP. Idk much about that one either))

        Also, in my research, I’ve found something about the distinction between lossless JXL vs lossy JXL. Seems like you wouldn’t be able to tell if the image is lossy or lossless just from it being a JXL
