FaceFusion

Face Fusion is an AI-driven face swap or face fusion tool that combines, replaces, or blends faces in photos and videos. Using sophisticated machine learning models, it detects facial landmarks and textures, then merges a “source face” onto a “target” image or video. It supports not only simple swaps, but also enhancements like lip-sync (synchronizing mouth movement with speech), fine masking, blending, or even minor age / gender style transformations.

This tool is often packaged as open source or via downloadable software, so users can run it locally or on servers. Because many parts are customizable — choice of face models (like InSwapper, enhancement nets), masking strength, blending ratio, and resolution enhancements — users can get results that feel realistic and natural rather than obviously edited. It also supports batch processing (many images/videos at once) and fine-tuning parameters to reduce artifacts or mismatches.

Face Fusion is especially interesting to creators, filmmakers, hobbyists, and AI experimenters. You can take a static face image and swap it into scenes, animate content, or adapt for creative projects. However, due to the power of face swapping, it carries ethical and legal responsibilities: you should avoid misuse, unauthorized impersonation, or violating privacy or copyright.
