Cut Paste Photo Editor is a handy app that allows you to easily cut and paste photos from one image to another. This is extremely useful for those who love to take pictures and also need to make a collage or use an image for a poster. 

It offers many options for users to choose from, including:

Cutout: This option allows you to create a transparent image by simply removing the unwanted part from the original photo. 

Paste: This option lets you paste the image from the Cutout tool on any of our existing backgrounds. 

Manual Erase: You can remove the background manually by using your finger rub technique.
