Truly Excellent (and Simple!) Batch Image Compression Software

I bought this app to help with compressing screenshot images taken on a 5K retina iMac. They were ~10MB each and, after a few simple adjustments based on how much compression I wanted versus quality degradation, it compressed them and put them into a “Compress” folder within the original images folder. I take issue with the reviewer who gave one star based on it putting the new images in a separate folder in the same location as the original images. It’s an unfair review and hurts the quality impression of what I feel is a very good app. I have used it to compress over 100 images so far and it hasn’t crashed once nor have any of the images had any issues. This is exceptional software at its finest, well done developer.

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.
