Crunch is an OS X tool for PNG image file optimization. Created by Chris Simpkins Crunch – Insane(ly slow but wicked good) PNG image optimization. It combines selective bit depth, color type, and color palette reduction with zopfli DEFLATE compression algorithm encoding using embedded versions of the pngquant and zopflipng PNG optimization tools. This leads to a significant file size gain at the expense of longer file optimization processing times and relatively modest decrease in image quality (see example images below).
