Reduce PNG Graphic Size Using PNGCRUSH
Now that I'm knee-deep in MacBook I love working with command line applications. There's a certain beauty in the simplicity of using the console instead of a nice GUI. One task I use the console for often is reducing the size of PNG files using the powerhouse that is PNGCRUSH.

pngcrush -reduce -brute source.png destination.png
Best pngcrush method = 113 (fm 0 zl 9 zs 0) for destination.png
(33.38% IDAT reduction)
(33.43% filesize reduction)
