AI-powered face swapping works very differently from app filters and masks. The algorithm analyzes the face in your source photo — its position, angle, lighting and shadows — and blends it into the target photo while matching those same parameters. Light falls correctly, skin tone matches the surroundings, and the result looks natural.
You just need two photos: the image you want the face placed onto, and a photo of the person whose face you want to use. Processing takes a few seconds and costs only 2 credit, making it one of the most affordable tools on the platform. Clear photos with a well-visible face work best.
If you want to place a person into an entirely new scene rather than just swap a face, try the AI photoshoot tool or the photo editor powered by Nano Banana 2.
