ImageOptim

ImageOptim is a GUI for lossless image optimization tools: PNGOUT, AdvPNG, Pngcrush, OptiPNG, JpegOptim, MozJPEG, Gifsicle, SVGO, and svgcleaner.

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

cd optipng # or gifsicle, or pngquant
make clean
make
