Reverse image search means uploading an image to search instead of keywords about the topic. By searching in such a way, you will be able to get more information about individuals, objects, or any other topic. It is also possible to search by entering the URL to the image as input instead of an image. Reverse image search is powered by a content-based image retrieval query.
