PhotoStack is a great app for resizing and adding watermarks to photos on your Android smartphone. With a simple interface, all you have to do is follow a few easy steps in order to resize your image however you want.
It's worth noting that PhotoStack is run on your smartphone's browser. However, this doesn't create any inconveniences when it comes to resizing your photos, since everything you need is right there. In fact, there's a section for both of the features included with this app.
When it comes to resizing a photo, all you have to do is select the photo in question and select the new measurements you want it to have. On the other hand, if you want to add a watermark, you can do that, too. Just choose where you want to put it.
PhotoStack is an interesting app that makes it very easy to adjust the size of your photos. Adding a watermark is another useful feature to help you prove that the photo is yours.
