FaceSeek — start with a face
When your target is a person, begin with a reverse face search. Unlike image search, it matches the same face across different photos, so it finds people even when the picture is different. It's free to try daily and is the fastest way to confirm an identity.

Frequently asked questions
What's the best way to find someone online?
Start from your strongest identifier. A clear photo is often best — a reverse face search shows where that face appears. From a name, use people-search databases; from a handle, use username tools.
Are people search tools accurate?
They return leads that must be verified. Records can be outdated or belong to a different person with the same name, so confirm with a second, independent source.
Can I find someone with just a photo?
Yes — a reverse face search like FaceSeek finds where a face appears across the public web, which often reveals names and profiles you can then verify.
