Add Lossy please ! #17

Thank you very much for Efficient-Compression-Tool !! Have you think for lossy switch for PNG and JPG? It will be very nice if you add this to this great optimiser !! Thanks again

I have tried to keep ECT focused on one task up to now, but lossy support could simplify some use cases. I will think about it and possibly support lossy compression next year.

Adding 256 color optimization to PNG would be helpful, though there are other tools that do this already: http://css-ig.net/articles/lossy-png-optimization Add lossy jpg compression is problematic; how do you know if too much compression is applied?

256 color will be Awesome !! I can't wait to see this in your tool ... Keep going this project and thank you !!

256 color is already done pretty well by pngquant. for JPEG (lossless optimization, or lossy (re)compression), there is mozjpeg. IMO this is out of scope.
