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

  • Great single-purpose image optimizer.

  • 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.
