What is it?

Search by Image is a browser extension for reverse image searches. It supports more than 30 search engines, which can be toggled and reordered from the extension's options. It is aimed at journalists and researchers checking whether an image is authentic, at people tracing where their photos appear online, and at shoppers looking for similar products.

Images are detected at the selected area regardless of how they are embedded in the page. The default mode searches with the image URL, while the select image mode uploads the image file itself, which helps with sites that do not allow direct linking. Other modes include capturing an area of the page, browsing for a file on your device or pasting from the clipboard, and searching with a URL.

The search mode can be set separately for the context menu and the browser toolbar. The extension is available for Chrome, Edge, Firefox, Opera, Safari and Samsung Galaxy Store, with Mac and iOS builds for Safari.
