Install once and forget the buttons — automatic, private, offline QR scanning
The extension watches pages as they load and decodes any QR code that appears, so you rarely need to press a scan button.
You can also decode a QR code on demand straight from the extension's popup menu when auto-detection is not convenient.
Turn a page link or selected text into a QR code and download the resulting image for sharing or printing.
The developer states the extension does not transmit or store user information, and the Chrome Web Store privacy label confirms no data collection.
