Learn: reverse face search, explained plainly

What you’ll find here

Reverse face search is a specific technology, distinct from reverse image search, and most people encounter it for the first time when they already have an urgent question — is this dating profile real, has my photo been stolen, is this person who they say they are. This hub collects the background you need to use a face search well: what it can realistically find, what it can’t, and how to read the results without over-trusting a single score.

We write these guides the same way we write the rest of this site: no invented accuracy percentages, no implied guarantees. Where something is genuinely uncertain — like exactly how much of the public web any index covers — we say so instead of making up a number that sounds authoritative.

Start with your situation

If you’re trying to figure out whether reverse face search is the right tool at all, start with the complete guide and the comparison with reverse image search — a surprising number of searches fail simply because someone used the wrong tool for the job (a Google Images search for a face that appears in a different photo entirely).

If you’re specifically evaluating a dating match, go straight to how to spot a catfish and our deeper article on AI-generated faces and catfishing. If you’re trying to calibrate your expectations before paying for a search, read how accurate is face search, really and our photo-quality guidance — the single biggest lever you control is the photo you upload. And if you’re wondering whether any of this is legal to do in the first place, this guide covers the general landscape.

For situation-specific walkthroughs — reconnecting with an old friend, responding to stolen photos — pair these guides with our find old friends use case or what to do if someone stole your photos. When you are ready to pick a tool, the Yandex and Lenso.ai comparisons explain where free reverse image search stops and dedicated face matching begins.
