Two sources → one result

Face Swap is different from a normal AI filter: it uses a base frame plus a separate face source. The result keeps the scene from the first photo and transfers the face from the second.

What helps create a realistic Face Swap

A strong result starts with a suitable pair of images rather than more controls.

What helps

  • One clearly visible face in each photo
  • The face is large enough and sharp
  • Camera angle and lighting are not drastically different
  • Hands or objects do not heavily cover the face

What often hurts quality

  • Strong blur or a very small face
  • Several people in either photo
  • Deep profile paired with a frontal face source
  • Masks, glasses, hair, or objects heavily covering the face

What changes and what stays from the base photo

Face Swap transfers a face rather than rebuilding the entire scene from scratch.

FACE

The face changes

Facial identity comes from photo #2.

HAIR

Hair stays

The hairstyle and hair remain from the base image.

BODY

Pose and clothing stay

Body, clothing, and position remain from the main frame.

SCENE

The scene stays

Background, composition, and camera framing remain from the base photo.

FAQ

Frequently asked questions about Face Swap

How do I replace a face in a photo online?

Upload the base photo as Source A, then upload the face photo as Source B, confirm that you have the right to use both images, and run Face Swap.

Which photo should I upload first?

Start with the base image. Its pose, clothing, hair, background, and composition are what the result should keep.

Do I need to crop the face manually?

No. The current Face Swap uses the complete second photo and does not require manual face cropping.

Can I try it for free?

Yes, if the shared SmartGenius guest AI try has not already been used. After a successful demo generation, registration is required to continue.

Why can Face Swap fail?

The service may not detect a face, may find multiple faces, or may reject an unsuitable image pair. Try clearer photos with one person in each image.

Does it work on mobile?

Yes. JPEG, PNG, and WebP uploads are supported on phones and desktop browsers.

Connect two photos with Face Swap

Upload the base image and the face source above — the result appears in the same interactive workspace.
