Chroma Key Remover Support
An Android app for removing a solid-color photo background and saving a transparent PNG.
Getting started
Choose a photo and select the background color to remove. Adjust the result in the preview, then save it as a transparent PNG to the photo library or a folder you choose.
Troubleshooting
If the background is not removed as expected, review the selected color and adjustment values. Transparent areas can look different in different viewers; also check the result in a PNG-capable image viewer. For saving issues, check available device storage and the destination.
Keeping your data
Save the current draft as a PNG before clearing app data or reinstalling if you want to keep it. Manage exported images separately at their destination.
App-private data is excluded from cloud backup and device-to-device transfer. Backup of saved PNGs follows the destination and device settings.
