ImageMagick
ImageMagick is a software suite to create, edit, and compose bitmap images. It can read, convert and write images in a variety of formats (about 100) including GIF, JPEG, JPEG-2000, PNG, PDF, PhotoCD, TIFF, and DPX.
ImageOptim makes images load faster. Removes bloated metadata. Saves disk space & bandwidth by compressing images without losing quality.
imageoptim is excellent for publishing images on the web (easily shrinks images “saved for web” in photoshop). it's useful for making mac and iphone/ipad applications smaller (if you configure xcode to allow better optimization). imageoptim 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).

how does it work?when you drag'n'drop images into imageoptim's window it will run several image optimization tools automatically and combine their results, ensuring that you always get the smallest file. imageoptim integrates well with os x, so you can also drop files on imageoptim's dock icon, or use services menu in finder, or markup menu on attached images in apple mail. imageoptim can also be launched from command line. a special option for even smaller files. if you enable lossy minification you'll get smallest file sizes possible. by default imageoptim is very cautious and exactly preserves image quality, but if you allow it to change the quality?—?even only a little?—?it will be free to use much more aggressive optimizations that give the biggest results. you can configure lossy optimizations in imageoptim's preferences. imageoptim can apply lossy compression not only to jpeg, but anim gif and png as well!
