What Is This Tool?
The QR Code Scanner reads QR codes from an uploaded image or your device camera and shows the decoded text or link.
What Can You Do With It?
Read a QR code from a screenshot. Check where a QR code link goes before opening it. Scan codes on a laptop using the webcam.
How Does It Work?
Image pixels are read in the browser and decoded with the jsQR library. For camera scanning, video frames are checked until a code is found; the camera is released when scanning stops.
Key Benefits
Works with images and live camera. Lets you inspect a link before visiting it.
Limitations and Important Notes
Blurry, tiny or low-contrast codes may not be read. Camera access needs your permission and a secure (https) connection. Only QR codes are supported, not other barcode types.
Privacy and Security
Images and camera frames are processed in your browser and are not uploaded. The camera stops when you stop scanning or leave the page.
Real-World Example
Upload a screenshot of a QR code from a restaurant menu. The scanner shows the text https://example.com/menu, which you can copy or open.
