How to Swap Two Faces in One Photo

The classic gag is the mutual switch: you and a friend trade faces in the same shot. The result is uncanny in the best way because the bodies, poses, and setting stay identical — only the faces move.

The more common practical need is selective: a group photo where you want your face on one specific body, leaving everyone else untouched. This is where face mapping matters — a good app detects every face and lets you tap the exact one to replace.

Both work best when the faces are roughly the same size and angle in the original. Wildly different head sizes or one profile and one front-facing shot make the blend harder.

Step by step

1. Pick the photo with multiple faces. Load the group or two-person shot as your target.
2. Let the app detect faces. AnyFace outlines every face it finds in the photo.
3. Tap the face to replace. Select exactly which detected face you want to swap.
4. Choose the source face. Pick the face that should replace it from your library or camera roll.
5. Repeat for a second face if switching. For a mutual switch, map the second face to the first person.
6. Generate. Run the swap and check both faces landed on the right bodies.

Tips for a clean result

• Similar head angles between the two faces produce the cleanest switch.
• For a group photo, zoom in before tapping so you select the right face.
• Save faces you reuse to your on-device library to skip re-picking.
