Multi Image Search is a browser extension designed to make reverse image searching easier across multiple search engines. For images found on websites, users can right-click a picture and search with a preferred engine or open a multi-engine menu to choose Google, Bing, Yandex, TinEye or Baidu. An option also allows searches across all enabled engines. Users can configure the default engine, choose which engines are available and change the interface language.

The extension also provides a shortcut for searching pictures stored on a computer. Its local image search menu opens the selected engine’s official image-search page, where users upload the file directly to that service. Multi Image Search states that it does not upload or handle local files itself. The extension is distributed as a CRX file, with installation instructions for browsers including Chrome, Edge, Brave and Opera. The site offers usage guides, a demonstration and an FAQ. Some search engines may be slow or unavailable in certain regions, and the guide suggests checking connectivity or using a proxy or VPN when needed.
