AV1 comes out on top of all of the comparisons to my eye. Seems to be half a step above JPEGXL, i.e. small AV1 is almost as good as medium JPEGXL

- bscphil 6y agoI find JPEGXL much better at medium and large sizes for the sorts of artifacts that bother me, on most images. For example in this [1] comparison, AV1 is clearly degrained, losing the very fine detail. Note that achieving high quality results at low bitrates is not really a goal of JPEGXL, or the codecs it's based on. For example the PIK readme contains the following note: > It prioritizes authenticity, a faithful representation of the original, over aesthetics achievable by by hallucinating details or 'enhancing' (e.g. sharpening/saturating) the input. So as I noted in the OP, it's not a very fair comparison with bitrates this low, but I think JPEGXL holds its own.
