TinEye – Reverse search using your Images

When you prepare your blog post, you may need to add several images, which will help your readers to understand better the content, or will make the post more attractive and readable. Let’s say, you have found an image but you are not satisfied with quality, resolution, or you prefer having the same pic, but without visible watermark. Definitely, you may continue image searching through the popular sites, but there might be difficulties to locate what you exactly need. Here, you find a new useful service - TinEye - a reverse image search engine.


Using it is quite simple. You submit an image to TinEye and find out where it came from, how it is being used, if modified versions of the image exist, or to find higher resolution versions. When you submit an image to be searched, TinEye creates a unique and compact digital signature or 'fingerprint' for it, then compares this fingerprint to every other image in the index to retrieve matches. TinEye can even find a partial fingerprint match.

Note that TinEye does not typically find similar images (i.e. a different image with the same subject matter); it finds exact matches including those that have been edited, like cropped or resized.

TinEye is the first image search engine on the web to use image identification technology rather than keywords, metadata or watermarks. It is free to use for non-commercial searching. TinEye regularly crawls the web, looking for new images, and in addition accepts contributions of complete online image collections. To date, TinEye has indexed out 1.8 million images from the web to help you find what you're looking for.

Free services limitation

The free for non-commercial use version of TinEye at tineye.com allows you to do up to 50 searches per day, up to 150 searches per week.


TinEye must be able to save your search image to permanently link to your search results. Unregistered users of TinEye cannot save their search images, as they are automatically discarded after 72 hours. Links to these searches will stop working after 72 hours, unless a registered user happens to save the same image. Registered users of TinEye can save their search images if history is enabled in their user Profile. Saved searches are available from the History page, and permanent URL links to any saved search can be bookmarked or shared with friends.
