    Great PNG optimizer! Extremely useful to design web sites, where each bit of info weights a gold.

    A wonderful tool that can be left running in the evening with -o7 -zm1-9, and in the morning thousands PNG’s are magically shrunk without quality loss. Run them in parallel terminal to double, triple, quadruple the fun!

    Very effective even at default settings, and fast too. My favorite PNG optimization tool.
