7 points · Open discussionIf anyone is interested in lossy PNG compression, please check out my project at https://github.com/foobaz/pngloss
It doesn't compress as well as JPEG or other formats that are designed to be lossy. But if you need PNG for some reason like alpha channel or application requirements, or if your image is particularly well-suited to my compression algorithm, it might be a good choice. For many images it does compare favorably to an 8-bit indexed PNG.
