ImageOptim makes images load faster by removing 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).
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 macOS, 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 or Sketch.
