What Is Face Swap?
Face Swap allows you to replace the face of any HeyGen avatar with a face from an uploaded photo. The system automatically maps facial features and lighting to create a realistic result while keeping the avatar’s movements and expressions intact.
It’s especially useful for:
Giving your avatar a custom appearance that resembles you or your brand representative
Creating unique looks for different projects or campaigns
Experimenting with visual styles for marketing, training, or entertainment
How to Access Face Swap
Go to your HeyGen homepage.
Click Apps → All Apps → Face Swap.
You’ll be redirected to the Face Swap interface.
How to Use Face Swap
Upload an Avatar
Choose the avatar whose face you want to modify.
Upload a Photo
Upload a clear, front-facing photo of the person whose face you want to apply. Make sure the photo is well-lit and unobstructed.
Preview the Swap
The app will automatically process and apply the new face to your selected avatar. You’ll see a real-time preview of the result.
Generate and Save
Once you’re satisfied with how it looks, click Save to My Avatars to finalize your customized avatar. You can then use this avatar in your AI Studio projects or other HeyGen apps.
Note:
Make sure to choose a photo that's at least 720p.
For best results, choose a well-lit photo with a clearly visible face, looking directly at the camera.
Avoid photos that show side profiles, are overexposed or blurry, include masks, or feature cartoon-style images.
