This app has saved me lots of time by completely automating the compression and optimizations of my product images. The image previewer is particularly helpful for placing watermarks on my photos. It really does offer the best features at the best value. When I contacted support with questions, they always provided prompt solutions and even enabled special functionality for my account because I did not want the first image of every product watermarked. Thanks!

Not worth it. We paid for the APP and then it stopped working. If you want to return the images back to the way they were before, you will need to do it one by one NOT in bulk. Their servers are really slow. Paid for nothing and no refund.
