Works great!

With Yosemite’s Preview app not actually compressing images now, I needed a way to do the job. Even if Preview wasn’t broken, I prefer Compress. I gives you a slider and displays what size ithe image will be and shows a preview Before and After. The batch processing works well, you just have to go the Compress folder, then drag the edited image to its desired location.

Blown away!

I need to whittle down the size of a lot of photographs on my web site but I absolutely do not want to make any compromises on the visual quality. The very first image that I compressed with this great utility more than paid for the price of the app. I’m a happy camper. Thanks to the programmer for this quality piece of workmanship.

Amazing compression capabilities

Great to optimize images for web design. The app is really fast and the preview is a very nice feature.
