It's helpful when you need to post/send smth but the image is to big. You simply need to drag and drop the picture to get resized one. So there's no need to use PS or any other complex editor.
It looks like the makers of this little, handy tool not only did their homework but also somehow peaked what most of us would consider a perfect web app. It's such a nice surprise when a free tool not only works but also works so beautifully well, without any nasty surprises like "image too large, exceeding file-size limit" or"big image, so pay now". Love and respect!
Tried with several images, not compressing that much at all compared to some other sites :/
