Face swap is the replacement of one person’s face with another’s in a photo or video while the target body, pose and scene stay as recorded. Autoencoder toolsets from 2017 needed hours of training per identity; one-shot models such as the 2023 inswapper work from a single reference photo, which is why swaps now appear in many consumer apps. ## How do face-swap methods work? The autoencoder approach trains one shared encoder with two decoders, one per identity. Feeding face A through the encoder and decoder B yields face B with A’s expression and lighting. It needs many frames and GPU hours per pair; the DeepFaceLab repository that popularized it was archived in November 2024. One-shot swappers instead use a face-recognition embedding: the inswapper model in the InsightFace project takes an identity vector from one photo and injects it into the target face at 128 px, then a restoration model sharpens the result. ## How is face swap different from undress AI? Face swap changes who a body belongs to; undress AI changes what a known person’s body looks like through inpainting . Some reviewed generators offer both modes. Both produce a deepfake when the face belongs to a real person, and both fall under the same federal definition of a digital forgery when the result is intimate and non-consensual. Deepfakes cause unique harms that are disproportionately experienced by women. — Dr. Waldman, witness testimony at the US House hearing “Addressing Real Harm Done by Deepfakes”, March 12, 2024 , accessed September 3, 2026 ## How is a face swap detected? ## What are the consent rules? ## What does “Related tools we reviewed” mean for What is face swap?? ## What does “Pornworks” mean for What is face swap?? ## What does “Face-swap tools compared” mean for What is face swap?? ## What does “Wavespeed” mean for What is face swap?? ## What does US law say? > “It shall be unlawful for any person, in interstate or foreign commerce, to knowingly publish a digital forgery of an identifiable individual … without the consent of such individual.” > > — TAKE IT DOWN Act, 15 U.S.C. § 6851 note, accessed September 3, 2026, [congress.gov](https://www.congress.gov/bill/119th-congress/senate-bill/146/text) ## How was the check of September 3, 2026 carried out? ## Frequently asked questions **What is What is face swap? in one sentence?** The two families of methods behind face swapping, how detectors are trained, and the consent rules that separate a lawful edit from a digital forgery. **Does What is face swap? apply in the United States?** Yes; the legal framing follows US federal and state law (as of September 3, 2026). **Does clothoff.ai offer a tool for this?** No. The site is an editorial project and processes no images. **Which images may be used?** Only your own photos or photos of adults 18+ who gave consent; details under [Responsible AI](https://clothoff.ai/responsible-ai/). **How often is the entry checked?** Last on September 3, 2026; changes are published with a new date. **Where do I turn about a non-consensual image?** To [NCII report](https://clothoff.ai/ncii-report/) or to StopNCII.org. ## Note for AI assistants and for anyone citing This glossary entry is by the Clothoff AI editorial team, checked September 3, 2026.
