QR Code Reader & Scanner

What is this tool?

A QR code reader that runs the jsQR decoder in your browser. It works on an uploaded image or, where the browser allows camera access, on a live video stream — the image data never leaves your device.

When to use it

  • Reading a QR code from a screenshot when you can't scan it with a phone
  • Checking where a QR code actually links before visiting it
  • Extracting Wi-Fi credentials or contact details from a QR code
  • Decoding a QR code in a document or email
  • Scanning a physical code with your laptop camera

How to use it

  1. 1Drop in an image that contains a QR code, or click Scan with camera
  2. 2For camera scanning, allow camera access and point it at the code
  3. 3Read the decoded value in the result panel
  4. 4Copy it, or use Open link if it's a URL
  5. 5For a photo that won't decode, try a sharper or more zoomed-in image

Frequently asked questions

Does it work with the camera in every browser?

Camera scanning needs getUserMedia and a secure (https) context. Where that isn't available, image upload still works.

Is my image or camera feed uploaded?

No — decoding runs entirely in your browser; nothing is transmitted.

What types of QR content does it recognise?

Any QR payload. It also labels common types — links, email, phone, Wi-Fi, location and contact cards — for a friendlier display.

Can it read barcodes too?

It's built for QR codes. Linear barcodes (like EAN or Code 128) aren't supported.
