Looking for a simple piece of Mac software to compress and optimize your photos or images for the web? Look no further, as there is a software called ImageOptim that will get the job done quickly and efficiently. ImageOptim is free to download, open source, and even support OS X 10.8 Mountain Lion.
Since our hosting provider WPEngine does not allow the WP Smush.it plugin, I was forced to use their browser-based service. After having issues with it spitting out my compressed image incorrectly the past few days, I decided to look for an alternative route and landed on ImageOptim. Since installing it this morning, I have used it for a number of images and have been impressed with the results.
The interface is ridiculously simple and it does not take long to achieve the proper optimization. An advantage to using this software compared to the WPSmushit service is that you don't have to rely on a 3rd party to initiate the compression and you have full access to its functionality regardless of whether you have an active Internet connection or not.
ImageOptim can handle batch image processing and best of all, it replaces the original larger file with its compressed version so there is no more dealing with duplicate files that often cause an organizational nightmare and take up critical space on your hard disk.
