Add Background
Drop in a PNG (or any image — transparent pixels keep their alpha, opaque pixels are unchanged). Pick a background color and an optional padding amount, and download the composite. Useful right after Remove Background for product photos, profile pictures with a brand color, or screenshots that need a frame. Runs entirely in your browser — files never leave your device.
