QR Code Decoder

Decode QR codes from uploaded images. Extract URLs, text, and data from any QR code image.

Need to read a QR code from a screenshot or image file? This decoder takes a QR code image URL and extracts the encoded content. It uses the browser's built-in BarcodeDetector API where available, with clear messaging about browser support.

The decoded content is analyzed to detect whether it contains a URL, email, phone number, or plain text. Everything runs in your browser with no data sent to any server.
