How to Swap Faces in a Video
Two uploads, one click, a finished MP4 in your browser. Nothing to install; a free account is all you need.
Pick Your Source Face
Upload a JPEG or PNG portrait. Any clear, front-facing photo works. The AI reads the face identity from this one still image and uses it to replace every face in your video, frame by frame. iPhone photo saved as HEIC? Convert HEIC to JPG free first. Want to crop or touch up the photo before swapping? Use the free image editor, or turn any picture into a clean JPG with the JPG converter.
Upload the Target Video
Drop in an MP4, MOV or AVI. Free accounts can swap clips up to 20 seconds and 5 MB; Pro and Max go up to 60 seconds and 100 MB. The AI decodes every frame, detects the faces automatically, and keeps the same identity across the whole clip. No manual keyframing.
Preview and Download MP4
Your swapped video plays in the browser as soon as processing finishes. Hit Download to save a standard MP4, ready for YouTube, TikTok, Instagram Reels or any editing timeline. Need a looping animation instead? Try GIF Face Swap. Swapping a still photo? Use Photo Face Swap.
What Makes This Video Face Swap Different
Most online face swap tools handle still images. This one runs the same neural identity model on every individual frame of your clip, producing a result that holds up in motion, not just in a screenshot.
Each video frame is decoded, face-detected, and swapped independently. The model re-estimates face landmarks on every frame so the swap tracks motion, head turns, and expressions naturally.
Toggle Swap All Faces to replace every person visible in every frame simultaneously. Ideal for group shots, party clips, or any scene with multiple subjects on screen at once.
Skin tone, lighting direction, and smooth tonal changes are blended at the boundary of the swapped region so the inserted face matches the original video's colour grade and ambient light.
At 1.0 the swap is full and clean. At 0.5 it ghosts the original face underneath at 50% weight. The slider lets you dial in any ratio, useful for subtle compositing effects or intentional double-exposure looks.
Source clip and portrait are discarded when processing ends. The MP4 you download lives in My Files, 24 hours on a free account and for the length of a Pro or Max subscription, and no training set ever sees your footage.
The processor accepts all three major container formats. Output is always delivered as a standard H.264 MP4, compatible with every major platform, device, and video editor without re-encoding.
Video Face Swap for Creators, Marketers and Storytellers
Whether you are building a YouTube channel, shooting a short film, or just want to drop a friend's face into a viral moment, video face swap unlocks edits that would otherwise require a professional VFX studio and hours of rotoscoping.
Short-Form Video Content
TikTok, Instagram Reels and YouTube Shorts reward novelty. A face swap clip that puts your audience into a scene, movie moment or trending format stops the scroll and drives shares without any production budget.
Personalised Video Gifts
Putting someone's face into their favourite movie clip or a funny moment from the year is genuinely memorable. It takes under two minutes and produces a gift nobody else will give them.
Film and Casting Pre-Vis
Indie filmmakers and students use video face swap to prototype actor choices before production. Swap a face into a reference clip to show a director or client how a role could look without scheduling a screen test.
Comedy and Parody Channels
Comedic face swaps landed on YouTube long before the AI era, but doing them frame-accurately by hand required After Effects expertise. Now the same quality result takes a single upload and a click.
Marketing and Ad Localisation
Swap the presenter's face in a product ad (with their permission) to test different presenter options or localise a campaign without reshooting. Particularly useful for A/B testing video thumbnails and spokesperson variations.
Game and Fan Edits
Fan edits, machinima, game capture and trailer remixes all benefit from the ability to put a specific face onto in-game characters or cutscene footage without access to the source assets or engine.
How to Get a Clean, Stable Video Face Swap
The swap quality depends more on your input choices than on the model. These are the adjustments that make the most measurable difference.
-
1Shoot your source portrait close-up and square-on. The AI reads your identity from this one photo. A face that fills at least a third of the frame gives it far more detail to work with, which tightens the swap boundary on every video frame.
-
2Match the lighting angle between source and video. If the video was lit from the left and your source photo was lit from above, the blend will look flat at the jaw and temple. Where possible, choose a source photo taken in conditions similar to the target video.
-
3Trim to the active scene before uploading. Black leader, title cards and fade-in frames are all processed at full cost. Removing them cuts your frame count by 10 to 20% on a typical clip and shaves real time off processing.
-
4Use 1080p or lower. Avoid 4K. Higher resolution does not improve swap accuracy, because the face is analysed at a fixed internal size whatever the source. 4K files are much heavier to decode and encode for no gain in swap quality, and they hit the upload size limit sooner.
-
5Set Blend Strength to 0.85 if you see hard edges. A full 1.0 swap is cleanest on still faces, but motion blur and compression artifacts in the video sometimes make edge blending more visible. Dropping to 0.85 softens the join without noticeably reducing the swap effect.
-
6Encode your output as MP4 H.264 before re-uploading anywhere. The downloaded file is already in H.264. Avoid converting it to AVI or MOV before posting; extra codec conversions introduce re-compression artifacts that are most visible around the face region.
Limitations of This Tool
This tool does what it says, but there are real constraints to know about before uploading a long video or expecting broadcast-quality output.
Expect the swapped MP4 to come back without the original soundtrack: free results are re-encoded to add the watermark, which drops the audio track. Keep your source clip and add the audio back in CapCut, iMovie or DaVinci Resolve after downloading.
Every frame is swapped, so a video takes longer than a photo. Most clips finish in about two minutes; a full 60-second clip can take several. You do not have to keep the page open: each job runs in the background and you can follow its progress in My Files.
Profile angles, extreme head tilt, heavy occlusion (masks, hands over face, motion blur) will cause those frames to pass through unmodified with the original face intact. The model needs a mostly frontal view to detect landmarks reliably.
You can only provide one source face photo per submission. All detected faces in the video will be swapped to that same identity. There is no per-person or per-region targeting: if you need different faces swapped to different identities, run the tool once per identity.

Other Ways to Swap a Face
Video face swap processes full clips frame by frame. If you need a still photo swap or a looping animated GIF, these tools are purpose-built for those formats.
Also useful: generate a clip from a text prompt with the AI video generator, create stills with the AI image generator, compress a JPG if your source photo is over the upload limit, or take the how old do I look test - upload a selfie and let the AI age guesser judge it.
Remove the Limit. Swap Without Restriction.
A free account covers one clip a day, watermark included. Pro and Max raise that to 200 clips, stretch each one to 60 seconds, drop the watermark and bundle every other tool on AskAI.free, AI chat and image generation among them. Take the 7-day trial at no cost.
