Portal – background photo changer is a photo-editing app that automatically changes the background and allows you to move the image wherever you want.

How does it work?

You can either take a new photo with your camera, or pick one from your gallery. The app then automatically removes the background and allows you to replace it by several beautiful preinstalled images.

You can now even select an image from your gallery and use it as a background photo changer.

How to install and use it?

Make sure that you have a Wi-Fi connection or a cellular data connection. You need to download the app first.

Once the app is installed, open it.
