>>> In fact, in certain cases it can increase the size instead of compressing. Fwiw, all (lossless) compression algorithms will increase the size of some input

  > Fwiw, all (lossless) compression algorithms will increase the size of some inputs. They rarely meaningfully increase the size though. Typical compression algorithms, when faced with hard to compress sections, can add a handful of bits to wrap them up. Total overhead a fraction of a percent. When QOI encounters noisy pixels, it has to spend an extra byte per pixel, inflating the file by 33%.

    one pretty simple qoi improvement would be a tag to say to store the next n pixels uncompressed. I think there's room in the tags for adding it
