Face Swap
Face swap is an AI technique that replaces a face in an image or video with a different face, automatically matching the target's pose, lighting, skin tone and expression so the swapped face looks native to the scene.
A face swap model first detects and aligns both faces, then extracts an identity representation from the source face: the geometry and features that make it recognizably that person. It re-renders the target image with the source identity applied, while keeping the target's head pose, expression, lighting and surroundings. That separation of identity from pose and lighting is what makes modern swaps far more convincing than cut-and-paste edits.
Result quality tracks input quality. A sharp, front-facing, evenly lit source portrait swaps cleanly; extreme angles, heavy shadows, occlusions like sunglasses or hands, and low resolution all degrade the blend. When a swap looks off, the fix is almost always a better source photo rather than a different setting.
Legitimate uses are broader than the technology's reputation suggests: putting yourself into generated artwork or costume concepts, keeping one consistent face across a set of AI-generated marketing images, film-style previsualization, and entertainment effects.
The ethical line is consent. Only swap faces of people who have agreed, and never use the technique to impersonate, deceive or create intimate imagery of anyone. Arteza's face swap tool runs the swap in the browser on images you provide.
Frequently asked questions
How does AI face swap keep the result realistic?
The model separates identity from everything else. It applies the source face's features while preserving the target's pose, expression and lighting, then blends skin tone and edges so the face sits naturally in the scene.
What photos work best for face swapping?
Clear, well-lit, front-facing portraits with the whole face visible. Avoid sunglasses, harsh shadows, extreme angles and low-resolution images for both the source and the target.
Is face swapping legal?
Swapping with the consent of the people involved, for creative or entertainment purposes, is generally fine. Using someone's face without permission, especially to deceive or harass, can be illegal and violates platform policies.
