![]() ![]() How does ImageOptim compare to TinyPNG, MozJPEG or Guetzli? ImageOptim can apply lossy compression not only to JPEG, but SVG, animated GIF and PNG as well! You can configure lossy optimizations in ImageOptim’s Preferences. By default, it 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. The program 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. 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). It’s also useful for making Mac and iPhone/iPad applications smaller (if you configure Xcode to allow better optimization). ImageOptim for Mac can be used for publishing images on the web (easily shrinks images “Saved for Web” in Photoshop). ![]() 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 is a front-end (GUI) for lossless image optimization tools: PNGOUT, AdvPNG, Pngcrush, OptiPNG, JpegOptim, MozJPEG, jpegtran, and Gifsicle. ![]()
