Use AI video face swap to replace one face in a 1–30 second MP4. Add a reference portrait, sign in to generate, and preview the result with the original audio before downloading it.
Upload a short video and one reference portrait. Preview the face swap video online with its original audio, then save an MP4.
Your finished video will appear here.
Face tracking and final blending run in your browser. Xmax processes the clip, masks, and portrait.
The portrait provides the new identity, while the source clip provides the expressions and movement. Pick a shot with one person in view, then check that the replacement face follows their movements when they speak or turn.
The exported MP4 keeps the original AAC track, including dialogue, music, sound effects, and room noise. A silent source produces a silent export.
Play the face swap video online with sound and check the moments where the subject blinks, speaks, or turns away. Download the MP4 when you are ready to use it in an edit or review it on another device.
Choose a 1–30 second H.264 MP4, up to 32 MB, with AAC audio or no sound. If the recording is longer, trim a copy first. Leave enough time on either side of the action for the expression, reaction, or line of dialogue to make sense.
Choose one JPG, PNG, or WebP portrait up to 4 MB. A front-facing photo with even light helps keep the eyes, mouth, and face shape clear. Get permission to use both the source footage and the reference portrait.
Sign in and check the maximum credit cost before starting. Once processing finishes, watch the full result. Check that the face stays on the intended subject and that dialogue or sharp sounds line up with the picture. Download the MP4 from the workspace.
Try a reaction you filmed, such as a surprised glance followed by a laugh. Pick a moment with a clear expression and listen for the laugh in the preview to check that it still lands at the right time.
Choose a short speaking shot where the voice and timing already work. Keep one speaker in frame and watch their mouth through the whole sentence when you review the result.
For a vertical clip, leave room for the subject to move closer or turn without leaving the frame. Inspect the edges of the face in motion and play the exported file on the phone you use to publish.
Start with one steady shot. Hard cuts, hands covering the face, and a second person crossing the frame can make tracking harder. If the face is tiny in the source clip, try a closer shot so you can evaluate the result.
Use a sharp photo from a similar angle. A selfie taken from high above may give a poor match for a clip filmed at eye level. If the face drifts on a turn, try a different portrait or a less extreme shot.
Watch at normal speed first, then replay the hardest moment to track. Use headphones if the dialogue is quiet. If you see flicker or hear an audio mismatch, try a shorter clip.
The workspace is on this page. Sign in to check whether generation is available and see the credit quote. If your source is a webcam feed, use the Live Face Swap workspace linked below.
The workspace accepts a 1–30 second MP4 up to 32 MB, with H.264 video and AAC audio or no audio. For a longer recording, keep the original and trim a copy to the scene you want to edit.
Yes. If your source MP4 has AAC audio, the export keeps that track. A source with no audio track stays silent.
Generating a face swap from an uploaded video uses credits. Sign in to see the maximum credit cost in the workspace before you start. Previewing and downloading a completed MP4 do not use additional credits.
Use a recent browser with H.264 WebCodecs support. The workspace uses it to prepare the clip and export the finished MP4.
The workspace replaces one face per clip using one reference portrait. Choose a shot where the same person is clearly visible throughout.
Use footage and portraits you own or have permission to use, and get consent from both people. When you submit a job, Xmax processes the prepared clip, masks, and portrait. See the Privacy Policy for handling and retention details.
