FAQ

How do I read a QR code from an image?

Upload a JPG, PNG, or screenshot containing a QR code. The decoder scans the image and displays the encoded text or URL.

What types of data can a QR code contain?

URLs, plain text, email addresses, phone numbers, SMS messages, Wi-Fi credentials (SSID + password), vCard contacts, and calendar events.

Why can't the reader decode my QR code?

Common causes: image is too blurry, the QR code is at an extreme angle, there's insufficient contrast, or the quiet zone (white border) is cropped. Try a clearer screenshot.
