QR Code Scanner

Utility: Scan and decode QR codes using your device's camera, file upload, or clipboard paste.

Definitions: QR codes encode binary data or plain text in a 2D grid matrix of squares.

Technical Background: Decoded QR codes are processed client-side. The image data is read from canvas and analyzed using the jsQR library. Your data never leaves your browser.

Fun Fact: QR codes can store up to 3KB of data. A QR code's three distinct corners help the scanner align the orientation, meaning it can be scanned even upside down!
