ImageOptim

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

Building

Requires:

• Xcode
• Rust installed via rustup (not Homebrew).

git clone --recursive https://imageoptim.com 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
make
