ImageOptim is a GUI for lossless image optimization tools: Zopfli, PNGOUT, OxiPNG, AdvPNG, PNGCrush, JPEGOptim, Jpegtran, Guetzli, Gifsicle, SVGO, svgcleaner and MozJPEG.



git clone --recursive ImageOptim
cd ImageOptim

To get started, open imageoptim/ImageOptim.xcodeproj. It will automatically download and build all subprojects when run in Xcode.

In case of build errors, these sometimes help:

git submodule update --init
cd gifsicle # or pngquant
make clean
