QR code decoder
QR codes encode URLs, payment links, WiFi credentials, and contact cards as 2D barcodes. Upload a screenshot or photo — or use camera if supported — to read the payload without sending the image to a cloud OCR service.
How to decode a QR code
1. Upload PNG/JPG containing QR or allow camera access.
2. Center the code in frame with good contrast.
3. Read decoded text or URL result.
4. Verify link domain before visiting — phishing uses QR too.
