You can fork the code on GitHub and improve it! Feel free to contact me for assistance. ImageOptim is free, open-source software under terms of the GPL v2 or later. ImageOptim can apply lossy compression not only to JPEG, but SVG, anim GIF and PNG as well! Open Source You can configure lossy optimizations in ImageOptim's Preferences. If you enable Lossy minification you'll get smallest file sizes possible.īy 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. ImageOptim can also be launched from command line or Sketch. 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. 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 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). It's useful for making Mac and iPhone/ iPad applications smaller (if you configure Xcode to allow better optimization). ImageOptim is excellent for publishing images on the web (easily shrinks images “Saved for Web” in Photoshop). Old Mac?
