Reverse image search to verify a picture: Google Lens, TinEye, Bing and Yandex, step by step
A reverse image search finds other places a picture appears online. Upload the file, or paste a public image address, into Google Lens, TinEye, Bing Visual Search or Yandex Images, then read the matches. A match shows that copies exist. It does not show which copy came first, or whether a caption is true.
What does a reverse image search tell you?
It starts from a picture instead of words. The engine looks for pages that use the same picture, or one that looks like it. That helps with three questions: where else does this picture appear, is there a larger copy, and what did other pages say about it?
It does not tell you how the picture was made. A new picture may have no copies, and a copied one may have thousands.
How do you run the search in each engine?
All four work in a browser. Each offers an upload, and each also takes a public image address.
| Engine | How to start | What it says about your image |
|---|---|---|
| Google Lens | On google.com, select "Search by image" in the search box. The panel says "Drag an image here or upload a file" and has a "Paste image link" box. Google's help page on searching with an image lists the same three routes. | Google says it may store the URLs you search, to improve its products and services. |
| TinEye | On tineye.com, upload, paste or drag an image, or type a link. TinEye's FAQ gives 20 megabytes as the maximum size and says images work best at 300 pixels or more in either dimension. | TinEye says it does not save or share your image, and does not track your searches. |
| Bing Visual Search | On Bing Images, select the camera icon. Microsoft's help page lists, for a computer, dropping in an image, taking a webcam photo, uploading a picture, and pasting an image or a link. | Microsoft says the photos you provide may be used to improve Bing image processing services. |
| Yandex Images | On yandex.com/images, select the camera icon. The panel says "Drag an image here" and offers a "Select file" button and an "Enter image URL" box. | The Yandex help pages we read do not say how uploaded images are handled. |
Uploading sends your image to that company. Each opens another company's site, you may need to sign in, and your image goes to them, not to us.
What did we find when we tested the links?
A link can ask an engine to search for a picture that is already public. On October 30, 2026 we ran each engine's address form in a browser with one public image address: the test picture CA.jpg in the c2pa-rs repository on GitHub.
| Engine | What happened |
|---|---|
| Google Lens | The link redirected to a results page with "Exact matches" and "Visual matches" tabs, and a written AI Overview. |
| TinEye | The search ran. It reported 0 matches, and said it had searched over 86.5 billion images. |
| Bing Visual Search | Both address forms we tried ran a search that afternoon and landed on a results page of shopping listings. An earlier test the same day landed on the plain Images page, so this behaviour changes. |
| Yandex Images | The search ran and showed a results page with "Similar images" and "Sites" sections. |
Lens, Bing and Yandex each returned results for the same picture: Lens a written overview, Bing shopping listings, Yandex similar images. TinEye returned none, which fits its statement that it looks for exact copies. We also found no engine that takes a local file through a link. A file on your device has to be uploaded on the engine's own site.
That is why our checker offers link-only cards and never pre-fills a search. It never holds a copy or a public link to your image. Our Privacy and method page says what the checker does with your file.
How do you read the results?
- Exact or similar. TinEye says it finds exact matches, including cropped, edited or resized copies, and does not typically find similar pictures. Google's results use separate tabs for exact and visual matches. The Yandex Browser help page says its image search results show exact copies of your image and similar images.
- Dates. TinEye lets you sort by oldest. It says the date is when its crawler found the image, not when the image first appeared online, and that it does not know that date. Treat it as a clue, never as the first use.
- Captions. A match shows that a page uses the picture. Whatever the page says about it is that page's claim, and the search does not check it.
- No match. TinEye's own no-match message says the cause is probably that it has not crawled a page where the picture appears. No match does not mean the picture is new or original.
- Watermarks. TinEye advises avoiding visibly watermarked images, because it may search for the watermark and not the picture.
Does it matter which file you search with?
Yes. A screenshot, a re-save or a platform copy is a different file from the original. We tested this on October 30, 2026. We drew each of the 9 real files we hold with a Content Credentials record on a canvas and saved them again as PNG and as JPEG (quality 0.92) in Chrome. After the re-save, 0 of the 9 files still read a record in our checker. This was one browser, not a platform. Our accuracy page covers our other tests.
So keep the original file if you have it, and search the web with that same file.
What this means when you check an image
Open the checker and choose the file. If it finds no signed record, no source label in the metadata and no Stable Diffusion watermark pattern, the headline reads "No supported provenance signals found". The line under it says: "This does not mean the image is real or human-made." It adds that most images lose these signals when shared, screenshotted or re-saved.
The checker also always shows the limits line: "These checks cannot determine whether an image is AI-generated." After a result it lists the four engines under "Find where else this image appears". Each card says to open the engine, use its upload or camera button and pick the same file. Reverse search reads the web; our checker reads the file. Neither says how a picture was made.

Frequently asked questions
- Can a reverse image search show that a picture is real?
- No. It shows where copies appear and what pages say about them. A widely copied picture can still be misdescribed.
- Which engine should I try first?
- TinEye says it looks for exact copies, while Google's results have separate tabs for exact and visual matches. Our test gave different answers in each, so a blank result in one does not rule out another.
- Does the engine keep my image?
- Each company answers for itself. TinEye says it does not save your image. Google says it may store the URLs you search. Microsoft says photos may be used to improve Bing image processing. We did not find a statement for Yandex.
- Can I search without uploading my file?
- Only if the picture is already public and you have its address. A private file has to be uploaded on the engine's own site.
