Instagram is the platform people most often want checked, and it is the one a plain reverse image search is worst at. Instagram photos get cropped square, filtered, re-uploaded and re-compressed until the file no longer resembles the original at all. Face search doesn't care: it compares the geometry of the face, so a heavily filtered repost still matches the original person.
Only public Instagram content can be searched. If an account is private, its photos are not in any index — ours or anyone else's — and any service that claims otherwise is lying to you.
Your photo stays on your device until you press search, and only the square you framed is sent. Checking the photo is free — you'll see the plans before anything is searched or charged. By continuing you confirm you have a lawful reason to look this person up.
Overwhelmingly: whether the person they're talking to is the person in the photos. Dating profiles and Instagram accounts get built from someone else's pictures constantly, and one photo appearing on four accounts under four different names settles the question in about twenty seconds. The second most common search is people looking themselves up, usually after a friend mentions seeing their photo somewhere odd.
A match means this face appears on that public page. It does not mean the account belongs to that person — that is exactly the point when you're hunting a stolen photo. Read the whole set: one account is a data point, the same face on six unrelated accounts with six different names is a pattern, and a pattern is the thing you can act on.
Filters change colour and contrast. Crops change framing. Neither moves the eyes relative to the nose, and that ratio is what a face signature is built from. What does break it: sunglasses, a hand across the face, extreme profile angles, and the very heavy beauty filters that reshape the jaw and eyes. If you have a choice of photos, pick the plainest one.
No, and nobody can. A private account's photos are only served to approved followers, so they never reach a crawler. If a service tells you it can search private accounts, it is either lying or showing you results from somewhere else entirely.
Sometimes. Deleted photos often survive on aggregator sites, in news embeds or on reposts, so the face can still turn up even after the original is gone. The link we give you may point at that copy rather than the original account.
Only if a photo of that same face is already public somewhere. Your own photo isn't in the index — it's the query, not the haystack. What we compare it against is what was already published.
One search covers all of them at once — the platform pages just explain what to expect from each. Start from a photo and you'll get matches from everywhere the face appears.
