I am very pleased with this purchase. I have to convert high-res photos and clipart to a web-based format. With this app, you can batch convert to a preset you define. Effortless! There may be other alternatives, but Yellow Mug’s app do what they say they do. If you haven’t tried SnapNDrag Pro or YemuZip, you won’t go wrong with these lifesaver tools. Whoever Yellow Mug is, you can tell he enjoys making apps useful and easy to use.
