Face Search provides reverse face search for locating the same person across different public-web photos rather than finding duplicate image files. Upload a JPG, PNG, or WEBP image, and the system detects the face, creates a facial-geometry representation, searches the FaceCheck.id index, and returns source URLs, page context, and similarity scores. A browser-based photo checker flags resolution, size, framing, and visibility problems before searching. The service supports guest previews and one-time credit packs that never expire, with no subscription required. Results are intended as leads for investigation, not legal identity proof. Users are encouraged to start with free reverse image search, open source pages, corroborate context, and follow privacy, legal, and ethical guidance.
