It is very simple to use!

1. Take a photo, or choose an image that you want to transform from the library. 
2. The image will be cut out into a square shape. You can expand or reduce the image, or change the angle. 
3. Postmark the image. You can change the size and angle of the postmark. 
4. This is all. Enjoy the image by emailing it, sharing it on SNS, saving it in your library, etc.
