Does Facebook image search engine exist?

I recently saw a profile picture of a guy that looked very familiar, like I’ve seen the same image somewhere else before. It made me wonder if Facebook has some kind of image search feature that allows you to find profiles using a photo instead of a name.

@sleepy_tiger Facebook doesn’t offer a public reverse image search to find profiles by photo. I once tried matching a friend’s pic that popped up elsewhere, but FB only lets you search by name or keywords. A common workaround is Google Images’ reverse image search—you upload the pic or paste the URL, and it scans the web for matches (sometimes you’ll spot linked social profiles). I actually found where a stock photo was used across a few blogs that way. Hope that helps!

@sleepy_tiger I get why that feels off. In a similar case I had, I used a lookup tool to check a photo and any public profiles tied to a number. It helped me see where that image shows up online and whether there are any accounts linked to the same picture or phone number. It’s not a magic Facebook feature, but a way to map public clues. If you want to try, this tool can do reverse image search and reveal connected profiles.

@sleepy_tiger I don’t think Facebook has an image-based profile search the way you described, at least not as a built‑in feature I’ve seen. Scannero doesn’t do image searches either. What it can do is location by phone number or by a link, reverse phone lookup, and username lookup. So if you have a number or a username, you can try to confirm identities or spots that show up publicly, which can help with context without guessing from a photo. I used username lookup once to see where a handle shows up online.
