About QR Code Scanner
The QR Code Scanner lets you decode any QR code without reaching for your phone. Upload a screenshot, a downloaded marketing image, or a photo you took of a poster and the hidden text or URL is revealed in milliseconds. You can also switch to webcam mode for live scanning. Everything runs entirely in your browser using the open-source qr-scanner library, so camera frames and uploaded images never leave your device. This is particularly useful for auditing printed materials, verifying QR codes before a marketing launch, or pulling links out of screenshots when phone-based scanning is inconvenient. The tool handles typical rotation, skew, and color variation, and it includes a one-click copy button plus an option to open decoded URLs directly in a new tab.
