"Eraser Background" is a free cutting and editing tool that can cut out a hole or make the background transparent. It's a great tool for editing photos or to make an original sticker.

To use it, you'll just have to press the Erase option on the upper left corner of the picture.

Select the desired picture you want to erase or make transparent.

After that, you will see the area you want to cut and you can erase that part with your finger. You'll also be able to erase the whole picture if you want.
