  • ImageOptim

  • ImageOptim is excellent for publishing images on the web (easily shrinks images โ€œSaved for Webโ€ in Photoshop). It's useful for making Mac and iPhone/iPad applications smaller (if you configure Xcode to allow better optimization). ImageOptim removes EXIF metaยญdata, 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 metaยญdata if you need it).
