>>7709050 actually has quality loss, which you can see if you put the two images on a difference layer.
Here. I actually sent the image through waifu2x first to remove all of the initial jpg noise, converted it to a png, then crushed it with pngcrush. Effectively, I increased the quality by removing the jpg noise. However, if you wish to keep the jpg noise for whatever reason, let me know.
