🔎 Reverse Image Search
Image search techniques made simple: upload a photo or paste a URL and search 6 engines at once. 100% free, nothing stored.
🔒 Your image is never stored on our servers longer than 24 hours and is never shared.
A nearly new iPhone for half the usual price. A designer sofa that looks showroom-fresh. A puppy-free zone of bargains that seem too generous to be real — on Facebook Marketplace, that feeling is worth listening to. Many Facebook Marketplace scams share one ingredient: photographs stolen from somebody else’s genuine listing. The seller never owned the item, never photographed it, and will never post it to you. The good news is that the photos themselves are the easiest part of the scam to check. A reverse image search takes a couple of minutes and can tell you whether those pictures belong to this seller — or to a dozen listings scattered across the internet.
Why stolen photos are the scammer’s favourite tool
A fake listing needs to look convincing fast, and writing a description is easy while taking believable photos is not — the scammer does not have the item. So they lift images from eBay listings, retailer websites, Gumtree adverts or other Marketplace posts, sometimes from sellers in entirely different countries. The pictures are real; only the listing is fake.
This matters because the photo is the one part of the listing the scammer cannot truly fake. Prices can be invented, profiles can be dressed up, and replies can be scripted, but a stolen photograph leaves a trail: the original copy is usually still online somewhere, attached to a different name, a different town, or a very different price. Finding that trail is exactly what reverse image search does. The same trick powers property fraud, incidentally — our guide to rental listing scams and checking property photos shows how stolen pictures are used to fake flats and houses, and the checking method there is the same one below.
Step 1: Save the listing photos properly
Start by capturing the seller’s photos at the best quality you can. On the Marketplace app, open each photo full-screen and screenshot it, or long-press to save where that option exists. On desktop, right-click the enlarged image and save it. A few habits improve your chances of a match:
- Save every photo, not just the first. Scammers sometimes mix one stolen image with generic ones; any single match is enough to walk away.
- Crop out the app frame. Trim away the Marketplace interface, the seller’s name bar and your phone’s status bar, so the search engine sees only the photograph itself.
- Keep the largest version. Small, heavily compressed copies match less reliably than big, sharp ones.
- Note the details. Backgrounds, plug sockets, car number plates, shop signage and even the weather in a window can later confirm where a photo really came from.
If the listing has a distinctive main photo — the item on a recognisable rug, in a particular room — that is your best search candidate. Distinctive backgrounds are hard for a scammer to explain away.
Step 2: Run the photos through a reverse image search
Now search each saved photo. Our free reverse image search tool checks one picture across six engines at once — Google Lens, TinEye, Bing, Yandex, Pinterest and Google — which saves running the same upload six times. Upload the cropped photo, run the search, and open the results from a couple of engines rather than relying on a single one, because each index covers different corners of the web.
Work through the photos one at a time and keep notes as you go: which photo you searched, what came back, and where. Methodical checking beats scrolling through one results page.
How to read the results
What comes back falls into a few recognisable patterns, and each tells you something different:
- The same photo on another selling site, under a different name. This is the clearest warning. If the identical sofa appears on eBay, a retailer page or a Marketplace listing in another city, your seller copied it. Our walkthrough on how to check if a photo is stolen goes deeper into comparing copies and dates.
- The same item, photographed by a retailer. If the “used, one careful owner” item turns out to be a manufacturer’s press photo, the seller has no real item to photograph — a serious red flag for a second-hand listing.
- Only similar-looking images. Lookalikes are not matches. Engines return visually similar products all the time; compare the background, angle and small details before drawing conclusions.
- Nothing at all. No match is not proof of honesty — see the next section.
Dates help, too. If the identical photo was posted months ago by an account on another continent, the person you are chatting with did not take it this morning, whatever they claim.
When the search finds nothing
A clean search lowers the risk; it does not remove it. Some stolen photos come from private groups, deleted listings or sources the engines have not indexed, and some scammers now alter images — flipping, cropping or filtering them — to weaken matches. If your first search comes back empty, the techniques in our guide to what to do when a reverse image search finds no results can help: try the flipped version, crop tighter to the item, and search the most distinctive background detail on its own.
Treat the photo check as one layer, not the whole defence. A genuine-looking search result should still be combined with the profile and payment checks below before any money moves.
Red flags beyond the photos
Stolen pictures rarely travel alone. Watch for the company they keep:
- A price that makes no sense. Scam listings are priced to make you act before you think — well below every comparable listing, with a story about moving house or needing a quick sale.
- Pressure to leave Marketplace. Being pushed to email, text or WhatsApp immediately, or to continue the deal away from Facebook’s systems, removes the protections and paper trail. Facebook’s own help and safety pages give similar advice about keeping communication on the platform.
- Payment methods with no comeback. Requests for bank transfer, gift cards, cryptocurrency or a “friends and family” payment to a stranger are classic — once sent, that money is effectively gone.
- A thin or strange profile. A profile created recently, with few friends, no history and a profile picture that itself looks like a stock photo, deserves extra suspicion. You can reverse search that profile photo too.
- Refusal to meet or show more. A seller who cannot produce one extra photo of the item — say, next to a handwritten note with today’s date — probably does not have it.
One sign alone might have an innocent explanation; a stolen photo plus any one of them is a combination to walk away from.
Buying safely when everything checks out
Most Marketplace sellers are genuine; a passed photo check lets you proceed with sensible precautions. Meet in a public place for smaller items, inspect before paying, and for posted items use a payment method with buyer protection rather than a direct transfer. The US Federal Trade Commission’s consumer advice covers online-shopping scams in general and is worth a read before any large purchase from a stranger.
Before you hand over the item, check for a fake payment screenshot.
One last point, since you will be uploading listing photos to search engines while you check: that process is safe for ordinary shopping pictures. Our explainer on whether reverse image search is safe covers what happens to an image after you submit it, so you can check sellers without handing over anything personal of your own.
FAQs
Can a reverse image search prove a Marketplace seller is a scammer?
Not on its own, but a match is powerful evidence. If the identical photo appears on another site under a different seller or in a different country, the person you are dealing with did not take it — and a seller lying about the photos is a seller to avoid.
What if the seller says the photos are theirs and the other listing stole them?
Check the dates and ask for proof only the owner could give: a fresh photo of the item beside a note with your name and today’s date. A genuine owner can do this in a minute; a scammer working from stolen pictures cannot.
Does no search result mean the listing is genuine?
No. It means the engines found no indexed copy, which can happen with photos taken from private groups or altered images. Combine a clean search with the profile, price and payment checks before trusting a listing.
Should I report a listing whose photos are stolen?
Yes. Use Marketplace’s report option on the listing and the seller’s profile, and include what you found. Reports help the platform remove repeat offenders who recycle the same stolen photographs across many fake listings.
