About ImageOptim
ImageOptim brings several image optimization tools together in a Mac application. It is useful for preparing image assets before publishing them on a website or sharing them with others.
The project combines optimizers for multiple formats. Check the app's options before processing originals so the chosen compression behavior fits your workflow. The official bundle includes PNGOUT under a separate license.
