JPEG-XL is both a lossy and lossless codec. It is already being used in Camera DNG format, making the RAW image smaller.

While lossy codec is hard to compare and up for debate. JPEG-XL is actually better as a lossless codec in terms of compression ratio and compression complexity. There is only one other codec that beats it but it is not open source.

What is the non-open source codec?

    HALIC is by far the best lossless codec in terms of speed/compression ratio. If lossy mode were similarly available, we might not be discussing all these issues. I think he stopped developing HALIC for a long time due to lack of interest.

    Its developer is also developing HALAC (High Availability Lossless Audio Compression). He recently released the source code for the first version of HALAC. And I don't think anyone cared.
