Reverse Image Search

What Is Reverse Image Search? Reverse image search is a technology that allows users to search for information using an image as the search query instead of text. Unlike traditional keyword-based searches, reverse image search processes visual content to find matches, retrieve metadata, or provide context about the image. This method has become indispensable for tasks like identifying the origin of an image, verifying its authenticity, discovering similar content, and detecting unauthorized usage of copyrighted material.
