Maybe add alternative links?:

Maybe, I'll see how these projects related with mine in terms of quality and speed. jpeg2png (already tested this) is a significantly slower and little blurry, but better on very low JPEG quality (which no one will actually use). Maybe options can change something, but I tried only default mode. knusperli looks no good at deblocking, even on examples from README.md. I need to take a closer look.

@ilyakurdyukov say:

Maybe

Ok.

knusperli is absolutely useless, I wonder why did Google post thing that bad in their github. It work so bad, that you can hardly notice difference between input and output when zooming in. Its processing time is little slower than quantsmooth (with AVX and OpenMP), but knusperli is completely unoptimized. Probably, knusperli can be greatly faster with optimizations, but its effect is so small that it makes no sense to use it.

Here you go. I have added alternatives and comparison.

Very good.
