Search by Image от Armin Sebastian

Search by Image is a browser extension for Firefox that makes effortless reverse image searches possible, and comes with support for more than 30 search engines.

Search by Image is an open source project made possible thanks to a community of awesome supporters. If you'd like to support the continued development of the extension, please consider contributing with Patreon, PayPal or Bitcoin.

The extension helps journalists and researchers verify the authenticity of images, and assists in the identification of false information on social media. Search by Image is also popular among photographers, helping artists explore how their work is shared on the web, while shoppers find it valuable for discovering similar products at discounted prices.

The extension enables you to search for images from the context menu and the browser toolbar with the help of a diverse set of reverse image search engines, which can be toggled and reordered from the extension's options. Visit the wiki for the full list of supported search engines.

Images positioned at the selected area are detected regardless of how they were embedded in the page. The extension also supports searching with images from your device, images from private sites, and captured areas of the page.

A handful of search modes are offered that serve different use cases. The search mode can be set independently for the context menu and the browser toolbar from the extension's options.

Search modes:

• Select URL: select an image on the page and search with the image URL. This is the default search mode.
• Select image: select an image on the page and search with the image file. This search mode is preferred for sites which do not allow the direct linking of images, such as private sites.
• Capture: search with a captured area of the page.
• Browse: search with an image from your device. Pasting images from the clipboard is also supported on desktop platforms.
• URL: search with an image URL.

The image you select during a search is sent to the requested service, such as Google Images. Visit the extension's privacy policy for more information.

The extension is also available for Chrome and Safari.
