ImageOptim is a front-end (GUI) for lossless image optimization tools: PNGOUT, AdvPNG, Pngcrush, OptiPNG, JpegOptim, MozJPEG, jpegtran, and Gifsicle. Images are made smaller (in terms of disk size) without losing quality, by recompressing them using the best combination of compression settings, better algorithms, and by removing optional, invisible information like comments.
ImageOptim can be used for publishing images on the web (easily shrinks images “Saved for Web” in Photoshop). It's also useful for making Mac and iPhone/iPad applications smaller (if you configure Xcode to allow better optimization).
Moreover, It removes EXIF metadata, such as GPS position and camera's serial number, so that you can publish images without exposing private information (but there's an option to keep the metadata if you need it).
