Open the Img Stop AI Face Swap and add two pictures: “Your photo” (the body, hair and background you want to keep) and “Face photo” (the face you want to put in). The on-device AI finds 478 points on each face, reshapes the new face to fit, matches its skin tone and light and blends the edges. Tap a face if a photo has several, adjust blend strength or edge softness, and download the result.
About the AI Face Swap
The Img Stop AI Face Swap puts the face from one photo onto a person in another. Instead of pasting a cut-out, it maps 478 face landmarks on both faces and warps the new face triangle by triangle, so it follows the head angle, jaw line and features of your photo. It then evens out the colour and shading so the face matches the neck and the light in the scene, and blends the border band by band so no hard edge is left.
Group photos work too: every face found is marked with a box, and you tap the one to change – or swap every face at once. An open mouth in your photo keeps its own teeth, and if the two heads are turned in opposite directions the face is mirrored to match. The AI model (Google’s MediaPipe Face Landmarker) downloads once and runs in your browser, so your photos never leave your device. Please only use photos of people who agree, and never use face swap to deceive or harass anyone.

Tips for the best result
- Use two photos where the faces look towards the camera and are lit from a similar side.
- Sharp, well-lit faces of a decent size give the most natural results; tiny faces look soft when enlarged.
- Glasses, hands or hair over the face are not swapped well – choose a clear face photo.
- Lower the blend strength slightly if the new face looks too different from the body.
- Turn on “Keep my eyes and mouth” to keep the original expression and gaze.
Frequently asked questions
How do I swap faces between two photos?
Add the photo you want to keep as “Your photo” and the photo with the new face as “Face photo”. The Img Stop AI Face Swap finds both faces, fits the new face onto your photo and shows a live preview. Click Download to save it.
Can I choose which face to swap in a group photo?
Yes. Every face that is found is shown with a box – tap the one you want in each photo. Tick “Swap every face in my photo” to give everyone in your photo the same new face.
Why does the swapped face look a bit different from the original person?
The new face takes on the shape, pose and lighting of your photo, because it is fitted onto the face that is already there. Similar head angles, lighting and photo quality give the closest likeness.
Are my photos uploaded to a server?
No. The face AI downloads once (about 13 MB) and runs in your browser. Both photos stay on your device.
Is it allowed to swap someone else’s face?
Only use photos of people who agree to it. Do not use face swap to deceive, impersonate, embarrass or harass anyone – in many countries that can also break the law.
Does it work with videos or animals?
No. The tool works with still photos of human faces. Faces that are very small, strongly turned away or covered may not be found.
