How it works

The page uses the third-party html5-qrcode JavaScript library, which accesses your device's camera (via the browser's standard camera permission flow) and analyzes the video feed to detect and decode QR code patterns, converting them back into their original text/URL/data, entirely in your browser.

Common use cases

Scanning a QR code on a poster, menu, or product without a separate app.|Quickly opening a website linked from a QR code.|Reading contact information shared via a QR code.|Testing QR codes you've created for accuracy.

Benefits

Free, works directly in your browser, and requires no separate app installation.

Limitations

Scanning requires a device with a camera and browser permission to access it; poor lighting, glare, or a damaged/low-quality QR code can prevent successful scanning; this tool does not verify that a decoded URL or contact is safe -- always check a link before visiting it.

Privacy & your data

This page uses the third-party html5-qrcode library to access your camera and decode QR codes directly in your browser -- decoding happens locally, not on the A2Z Tools server. Camera access is requested through the library's own interface following standard browser permission practices.

Frequently asked questions

Why does the page ask for camera access?
Scanning a QR code requires your device's camera to capture the code's image, so the scanner library requests camera permission through your browser's standard permission flow.
Is the scanned QR code content sent to a server?
No. Decoding happens directly in your browser using the html5-qrcode library; the QR code's content is not sent to or stored on the A2Z Tools server.
Does this tool check if a scanned link is safe?
No. It only decodes the QR code's content -- always verify a link, phone number, or email is legitimate before acting on it.
Is this tool free to use?
Yes, it's free with no signup required.
