faceswap4fun is more than a face swapper. Here are all ten tools: what each one does, what it costs, and which are free. Everything runs in the browser, on a phone or a computer.
Type a sentence describing a scene and get a video of 5 to 60 seconds. Attach a portrait and that face stays from the first frame to the last. 6 credits a second — 30 credits for 5 seconds. A clip takes about 10–25 minutes; leave the page and it will be in your library. More about AI video
Describe a person in Vietnamese or English — age, look, clothes, setting — and get a tall portrait photo. 3 credits an image. "Make a video from this image" sends that person straight to AI video. More about AI portraits
One portrait and one line you type: the face says it, lips in sync with every word. Four Vietnamese voices (two female, two male), up to 45 seconds. Priced by length: up to 15 seconds 10 credits, up to 30 seconds 16, up to 45 seconds 22. More about talking photos
The AI listens to the film (Vietnamese, English, Korean, or it detects the language), translates it and reads it over the film in Vietnamese, English, Korean, Chinese or Japanese, with the original turned down underneath. 2.5 credits a minute (3.5 with a high-definition Vietnamese voice). Preview the first 60 seconds free. More about narration
One video (up to 60 seconds, files up to 2.5 GB) and one face photo. In a group video, pick which person to change. 10 credits a video, covering up to 3 faces; each face beyond that is 3 credits more. More about video face swap
Put one face onto a still photo, done in seconds. 1 credit a photo. More about photo face swap
Brush over what you want gone — a stranger in the background, text, a blemish — and the background is painted back in. The standard version is free, 30 times a day; a deeper version for large areas is 3 credits. More about object removal
Pick the part to keep and download just that. Free, no sign-in. Files up to 2.5 GB and 30 minutes. More about cutting video
Join up to 5 clips into one, in the order you set. Free, no sign-in. More about merging videos
