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 is a fantastic front-end for your image optimization needs. It uses local resources (good for moderate to high power devices) and allows for lossless optimization too! It is highly customizable with different options for most optimization, fastest etc (but you must know your optimization algorithms). I do not like manually selecting files through the terminal, I prefer using a GUI and this fits my needs perfectly.

The best and easiest free GUI app for Mac for image optimisation.

Of course there are alternatives for other use cases and workflows which are equally fine. ImageOptim has found its place in my Dock over the years, though. It is handy to losslessly compress and remove metadata with dragging and dropping. Its braindead simple usability.

ImageOptim does what is says on the box. Effective and customizable it beats all similar commercial solutions.

What is ImageOptim?

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).

Faster web pages and apps Reduces image file sizes?—?so they take up less disk space and down­load faster?—?by applying advanced compression that preserves quality.

Image files scrubbed clean Removes invisible junk: private EXIF meta­data from digital cameras, embedded thumbnails, comments, and unnecessary color profiles.

Best tools with drag'n'drop Seamlessly combines all the best image optimization tools: MozJPEG, Pngcrush, pngquant, 7zip and Google Zopfli. All Free and

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!

Open Source ImageOptim is free, open-source soft­ware under terms of the GPL v2 or later.
