This is the only official TinEye extension for Firefox developed by the TinEye team. A Firefox Recommended Extension! About TinEye TinEye is a reverse image search engine that allows you to search by image. TinEye uses image identification technology, not keywords: when you upload an image to TinEye, TinEye creates a unique and compact digital signature or 'fingerprint' for it, then compares this fingerprint to every other image in the TinEye index to find matches. TinEye does not typically find similar images; it finds exact matches including those that have been cropped, edited or resized. If you have never used TinEye, check out our tutorial. TinEye is perfect for:

Image verification: find out if a news photo is really what it claims to be, or if that dating profile is a scammer using someone else’s headshot
Image attribution: track the original source and ownership of an image
Image licensing: see if an image is available from stock image websites to be licensed

Using TinEye is private. We don’t track your searches, keep your images or add them to the TinEye index. The only data we collect is the version of the extension that you’re using. For more information, please see our privacy policy.
