The tool is easy; the hardest part is deciding what to make. Here are seven ideas that reliably land, each a short clip and one photo away from done.
Grab a short, well-lit clip of a scene everyone knows and swap the lead's face for yours. Scenes where the actor faces the camera and holds still swap best — the dramatic close-up, not the fight sequence.
Film a few seconds of yourself, then use a friend's photo — with their blessing — as the source. Then do it the other way round. The two clips side by side are the joke.
A music-video close-up where the artist lip-syncs to camera is ideal material: front-on, steady, evenly lit. Swap in your face and you are suddenly fronting the band.
Pick a scene with two people and swap both — the tool can map different faces onto different people in the same shot — so you play the whole conversation.
Use a childhood photo of yourself as the source over a current clip, or the reverse. It is a gentler, stranger effect than swapping with someone else, and people find it oddly captivating.
Those looping reaction clips — the slow nod, the raised eyebrow — are short, front-on and perfect. Put your face on the reaction and you have a personal meme to drop into any chat.
Old film footage and vintage portraits make for a fun anachronism. Swap yourself into black-and-white footage and the mismatch is the whole charm.
Whatever you pick, the same two rules carry every idea: choose a clip where the face stays roughly front-on and is not blurred by fast motion, and use a clear, evenly lit source photo. A short clip finishes in about a minute, so it is quick to try another if the first does not land.
Face swapping isn't illegal in itself, but what you do with it can be. A practical look at consent, likeness rights and the sensible line.
You don't need to install anything to swap a face on a phone. Here is how to do it in a mobile browser and save the result to your gallery.
About a minute for a short clip — here is what decides the wait, from clip length to the difference between free and paid credits.
