QR Code Reader

This tool uses your device's camera or an uploaded image to detect and decode QR codes directly in the browser. No app install is required. On supported browsers, the BarcodeDetector API handles detection natively for fast, accurate results. On other browsers, a JavaScript fallback library provides the same functionality.

When you grant camera access, the tool captures video frames and analyses them in real time for QR code patterns. Detection happens locally on your device, so the camera feed is never sent to a server. You can also upload a screenshot or photo containing a QR code if you prefer not to use the camera.

QR codes store plain text, but that text is often formatted as a URL, email address, phone number, WiFi network credentials, calendar event, or vCard contact card. The tool detects the content type and displays it appropriately, with clickable links for URLs and structured views for WiFi and contact data.

URL QR codes are the most common and simply open a website. WiFi QR codes contain the network name, password, and encryption type, letting you connect without typing the password. vCard QR codes contain contact details like name, phone, and email. Plain text QR codes can hold any short message up to about 4,000 characters.
