How to swap a face in a video

Four steps, about a minute of waiting, and nothing to install. This page also covers the parts that decide whether the result looks good.

  1. Upload a video

    Up to 60 seconds. An MP4 straight from a phone works as-is — there is no need to convert or trim it first, beyond the length.

  2. Add a photo of the face you want

    One face, looking at the camera, in even light. This choice matters more than anything else on the page — see below.

  3. Pick which faces to replace

    Your browser scans the clip and shows the people it found, so you can swap one person in a group and leave the rest alone. If the scan is slow or fails, skip it — every face in the video is swapped instead, which is often what you wanted anyway.

  4. Download the result

    A short clip takes about a minute. The finished video stays in your history for 15 days, so you can come back for it.

Choosing the photo

Most disappointing results come from the photo, not the video. The model gets one still image and has to infer a whole head from it.

Choosing the video

Faces that stay roughly front-on swap best. Fast head turns, motion blur and heavy backlighting are where any face swap struggles, this one included. A face with a strong beard is harder than a clean-shaven one, because the swap has to reconcile two different textures along the jaw.

Only use faces you have the right to use. Consent is not a formality here — putting someone's face into a video without their agreement is harmful, and in many places illegal.
