Crunch is an image compression tool for lossy PNG image file optimization. Using a combination of selective bit depth, color palette reduction and color type, as well as zopfli DEFLATE compression algorithm encoding that employs the pngquant and zopflipng PNG optimization tools, Crunch is effectively able to optimize and compress images with minimal decrease in image quality. While it may produce file size gains larger than those produced by lossless approaches, the impact on image quality is often imperceptible, and optimized file sizes are still significantly lower than the original.
Features
- Aggressive space-saving optimization, with minimal loss of image quality
- Cross-platform (through crunch executable that supports parallel PNG image optimization on *nix platforms)
- Available through Crunch GUI, a native drag and drop GUI tool for macOS
- Available through Crunch Image(s), a right-click menu service for macOS
