How to compress PNG image? Maximum compression lossless quality

[FurkanGozukara]

Hello. I would like to compress PNG images what is the command?

I want to make it with lossless quality

how much time or CPU it takes doesn't matter

Previously I have used PNGOUTWin but I think it is now outdated

The PNG encoder is always lossless. You could compress the image with the ImageOptimizer class. But you might also want to consider other tools. A tool I heared about is optipng.
