TinEye is a reverse image search engine and is currently indexed more than 1.35 billion images from the Web. If you don’t know what is reverse image search, it’s akin to similar image search: by utilizing image recognition technology to help filter out search results.
For this functionality, users who search the images through this type of search engine are not search by text, instead they need to upload an image or type an image’s URL link to the search bar. This contrast with the conventional search engine approach, and TinEye potentially search all the images available on the Web and match the image that user uploaded, whether the images have been photoshoped.
From the results, you can compare the images one-by-one with the different pixel, format and the size of the pictures. Once you identify a particular picture better than the one you’ve just uploaded, you even can trace the original URL of the picture source and save it for your own use.
Try it out and compare the pictures yourself.
