Ratings and Reviews

I am impressed!


FINALLY! A resizing and watermarking app that handles photos of mixed aspect ratios correctly! I've tried many different apps like this over the years, and none of them handled mixed aspect ratios very well. I have always had to manually sort my photos by aspect before processing … not with this app, though! When using the snap functions for watermarking, it always placed the watermark where it was supposed to. Runs pretty quick too! I resized and watermarked 10 images that were over 30MB each (huge!) in less than 10 seconds.

Doesn’t work with Photos


The only reason I paid for this app because the features say it can “import directly from iPhoto by dragging images in” and “overwrite originals.” This does not work at all with Photos. I was hoping to drag a batch of photos in and have them reduce the size right from Photos. I understand that iPhoto is now Photos and this is most likely broken due to the change, but the developer should have been aware of this and noted the description for clarity.
