Indeed what I was looking for was lossy method, thank you for recommendation. I had pretty good results to my needs with "Crunch" https://github.com/chrissimpkins/Crunch (pngquant + zopflipng )

hello, I would like to compress the hell out of an png but Im getting few % of decrease compared to this website where I get about 45% compresspng.com Am I doing it wrong or OptiPNG cannot do something that the website is doing?

dont really know, but I tried to compress few png's and I get something between 1%-15%
