How does AI face swap work?

AI face swap online detects the source face in one image and maps it onto the target face in another. The model adjusts for lighting, angle, skin tone, and expression to produce a natural-looking composite.

Can I upload both the source face and target image?

Yes. Unfold Gen's AI face swap online tool lets you upload a source face image and a separate target image. The AI then swaps the face from the source into the target automatically.

Does the tool create realistic face blending?

Yes. The face swap AI free online model handles edge blending, color matching, and perspective adjustment to make the swapped face look as natural as possible in the target scene.

Can I clean up the result after a face swap?

Yes. After using AI face swap online, you can run the result through our Image Enhancer to sharpen details, or through Nano Banana 2 to make further edits with natural language.

Is the AI face swap tool free to use?

Yes. Free accounts receive daily credits that cover face swap operations. Each swap uses a small number of credits. No subscription or credit card is needed to start.

Can I use face swap results for commercial content?

Yes, but use responsibly. Face swap output can be used in creative projects, marketing, and content production. Always ensure you have the right to use the faces in your images and comply with applicable laws.

Does the face swap work with group photos?

The tool is designed for swapping one face at a time. For group photos, you can run the tool multiple times, targeting a different face in each pass.

What image quality works best for face swapping?

Clear, well-lit photos with faces at least 200 pixels wide produce the best results. Frontal or slightly angled faces work better than extreme profiles. Avoid heavily occluded or blurry source faces.

Is my data safe when I use the face swap tool?

Yes. All images are processed securely and not used for AI training. Uploads are stored temporarily for your convenience and can be deleted at any time.
