Deepswap

This is the reason most people sign up. Deepswap replaces a face across every frame of a clip, holding the likeness steady even as the subject turns, changes expression or moves quickly. The company claims a dedicated anti-flicker engine and frame-by-frame coverage so you don't get unswapped frames mid-video. One credit covers 15 seconds, and Premium raises the ceiling to 30-minute videos.

Deepswap swaps up to six faces in a single clip, which sets it apart from tools that only handle one subject. The hard part isn't detection, it's keeping different people straight, and the company built clustering specifically so the same person isn't split into separate faces across angles. In practice you still have to confirm the right faces by hand before rendering.

Not every job is a video. Photo swaps cost 0.1 credit each and GIFs cost 1 credit, so stills and loops are where the free tier and small credit packs go furthest. The photo editor is tuned for the usual requests: film role swaps, gender swap images and cosplay shots.

Premium unlocks HD face swap, and Deepswap says the pipeline is built for 4K video swapping. The current public output supports 1080p. Higher resolution matters when your swap is going on a large screen rather than a phone, and it's the main quality jump the paid plan buys over the free tier.

Deepswap bundles an image enhancer, a background remover and a cartoonizer alongside its face swapping. Each costs roughly 0.1 credit per photo. You'd normally open a second app to fix lighting or cut a background after a swap, so having them in the same workspace saves a step.

Developers can call Deepswap's face swap and video generation models through an API, with credits billed on the same scale as the website. Setup happens through the web dashboard, and there's a sales contact for larger volumes. That makes it viable to add face swapping to your own product instead of sending users to a third-party site.
