QR Quick Share by Alex Development

QR Generator instantly creates a QR code for the page you're currently visiting, so you can share it with any device that has a camera — no copying, no typing.
Just click the extension icon and the QR code is ready. You can also generate a QR code from any custom text or URL using the built-in input field. Download the result as a PNG with one click.
