AI Video Face Swap
Swap faces in a video online—no app, prompt, or manual masking needed. Upload the original clip, add an image or video showing the face you want to use, and click Generate to create your face swap.
HOW TO FACE SWAP A PHOTO IN 3 STEPS
Swapping a face takes two photos and one click. Here's the whole flow.
UPLOAD YOUR TARGET IMAGE UPLOAD YOUR TARGET IMAGE
Add the photo that has the face you want to replace. This is the scene, pose, and background you're keeping.
UPLOAD YOUR FACE UPLOAD YOUR FACE
Add a clear, front-facing photo of the face you want to swap in. This is the identity that gets mapped onto the target.
GENERATE YOUR SWAP GENERATE YOUR SWAP
Click Generate. The AI detects both faces, aligns them, and blends the new face into the target — matching skin tone and lighting. Download your result in seconds.
Examples
AI Video Face Swap Examples
Choose a sample video as your starting clip, then add your face reference as an image or video. Compare the original footage with the example result to see how expressions, head movement, and lighting affect a swap.
Use-Case
What You Can Create with Video Face Swap
Use your own footage and authorized face references for personal edits, creative tests, and short-form video ideas.
Memes and Reaction Videos
Put yourself into an original reaction clip for a personalized joke, celebration, or group-chat moment. Keep the edit playful and make its altered nature clear when sharing.
Social Clips and Personal Intros
Create a personalized introduction, greeting, or short social post using footage you own. Try a new face in the same clip without filming each variation again.
Presenter and Ad Concept Tests
Compare authorized presenter looks in a shared video concept before planning a new shoot. Treat the result as a creative draft, not evidence of a person's actual endorsement.
Costume and Character Scenes
Place your face into an original costume or character performance. Start with a clip whose outfit, body, and setting already match the scene you want.
What it is
What Is an AI Video Face Swap?
An AI video face swap replaces a face in existing footage using a separate image or video as the face reference. Your Target Video supplies the scene and performance. Your Face Reference supplies the facial identity you want to add. When both uploads are videos, they still serve these two different roles.
Unlike a text-to-video generator, this tool starts with a clip rather than a written description. The aim is to change the face while retaining the surrounding performance—not to redesign the body, outfit, or setting. Results can vary, so check important details before sharing.
Accuracy tips
What Makes a Video Face Swap Look Realistic?
A convincing result needs to work while the video is playing, not just in a still preview. Look for two things when reviewing your clip:
Recognizable Identity Through Movement: The face should remain recognizable as the subject smiles, speaks, or turns. Check for sudden changes around the eyes, mouth, and jaw, especially when the face moves away from the camera.
Lighting and Edges That Fit the Scene: The swapped face should fit the surrounding angle, shadows, and skin tones. Look for visible borders, color jumps, or flicker near the cheeks and hairline. Difficult angles and covered faces may need a clearer source clip.
Better Results
How to Get Better Video Face Swap Results
Give the tool clear inputs before trying a more demanding scene.
Choose a Clear Face Reference: Use a sharp image or video in which the replacement face is clearly visible. Avoid sunglasses, heavy filters, and hair or hands covering key features. For a video reference, prefer a steady, well-lit view of one person.
Keep the Video Face Easy to See: Start with footage in which the face is large enough to identify. A distant subject or heavily compressed video provides less useful detail.
Start with Simple Movement: Try a short, continuous shot with one clearly visible person. Rapid cuts, strong motion blur, and repeated obstructions make the result harder to keep consistent.
Use a Compatible Angle: A clear front-facing or mild three-quarter view is a useful starting point. Large differences between the face reference and the target video's head angle can make the swap more difficult.
Review the Whole Clip: Watch head turns, mouth movement, and changes in light. A good first frame does not guarantee that every moment will look the same.
Video Face Swap, Character Swap, or Motion Transfer?
Choose the edit that matches what you want to change.
| Your goal | Best starting point |
|---|---|
| Replace a face in a video you already have | Video face swap: the existing clip is the base, and a separate image or video supplies the replacement face. |
| Replace an entire character, including their body or outfit | Character replacement: a broader editing task that should not be assumed from face-swap functionality alone. |
| Make the character in an image follow a recorded performance | Motion transfer: the video guides the movement of a character from a separate image. |
For reference-driven character movement, explore AI Motion Transfer. Use this page when replacing the face is the main task.
Create Your Starting Materials
Already have both files? Go straight to the generator. If you need an original scene or portrait first, prepare it with another GPTProto tool, download it, and upload it here as a separate step.
Need a Video to Edit? Use the Unrestricted AI Video Generator to create an original scene from text or animate an image. Choose a result with one clearly visible face, then download the clip for your swap.
Need an Original Face Image? Use the Unrestricted AI Image Generator to develop a realistic portrait concept. Choose a clear, unobstructed face and test it on a short clip before building a longer project.
Working with Photos Instead? Open AI Face Swap Image to replace a face in a still image rather than a video.

Frequently Asked Questions
How do I switch faces in a video with AI?
Create a GPTProto account and add credits. Upload the video containing the face to replace, add an image or video of the new face, and click Generate. Preview the completed clip before downloading and sharing it.
Can I upload my own video instead of choosing an example?
Yes. Upload your own clip in the Target Video field, then add an image or video in the Face Reference field. Examples provide a starting point; you do not have to use one of them.
Can I use a video instead of a photo for the replacement face?
Yes. The face reference can be an image or video. Upload the clip you want to edit as the Target Video, then add the separate image or video showing the replacement face as the Face Reference. A video face reference does not turn this into a motion-transfer tool.
Do I need to write a prompt?
No. This AI face swap video generator uses your target video and face reference as its inputs. There is no prompt to write or manual face mask to draw.
Is this a video face swap app I need to install?
No. You use GPTProto's video face swap tool online in your browser. You do not need to install a separate face-switching app or set up local AI software.
What makes a good face reference and target video?
Use an image or video where the replacement face is clear and unobstructed. For the target video, start with a short, single-person clip with steady lighting and limited blur. Follow the upload requirements for each field.
Is video face swap free or unlimited?
This workflow uses prepaid GPTProto credits: create an account, add credits, and check the current cost before generating. It is not an unlimited free video face swap service. Each new generation uses credits.
Does face swapping replace the whole character?
No. Face swapping focuses on facial identity. It should not be treated as a way to replace the subject's body, clothing, or complete character design. Choose a source video that already contains the surrounding appearance you want.
Will a face swap change the speaker's voice?
Changing a face is not voice cloning or dubbing. An image or video face reference supplies facial identity; do not assume it also transfers a voice or soundtrack. Check the downloaded result's audio separately if sound matters to your project.
Why does my face swap look blurry or change during movement?
Blur, small faces, steep head angles, obstructions, and changing light can make a swap less consistent. Try a clearer face reference and a simpler target clip, then compare the result during movement rather than judging only the thumbnail.
What should I check before publishing a face-swapped video?
Confirm permission to use the footage and likenesses, review the output for visual errors, and follow the platform's rules for labeling altered media. For advertising or client work, also check the applicable platform and model terms. A swap does not create permission or an endorsement.
