Reverse Image Search Anywhere is a free, open-source (MIT) browser extension for Chrome, Firefox, Edge and Opera.
Most reverse-image tools work by handing a search engine the image's URL. That breaks the moment a site hides it. Instagram and Pinterest do, and so does anything drawn to a canvas or served as a blob: or data: URL. They also make you check one engine at a time, which is the slow half of the job.
This extension fixes both halves. Right-click any image and search Google Lens, Yandex, Bing Visual and TinEye, one engine or all of them at once. It also handles clipboard paste, region capture, and a face-search-first flow for finding people.
Privacy: plain searches never touch our servers. Uploads happen only when you ask for them, get a link that expires after 15 minutes, and the file is deleted automatically about a day after it arrives. The source is published here so you can check that rather than take it on trust.
