Reverse image search is a technology that allows users to find information about an image by uploading it or providing its URL. Instead of searching by keywords, the tool analyzes the visual content of the image to locate its source, find similar images, or gather related details across the web. This method is useful for verifying the authenticity of photos, tracking image usage, identifying people or objects, and discovering higher-resolution versions. Reverse image search is widely used in fact-checking, copyright enforcement, and digital investigations.
