What is a QR Code Scanner?

A QR Code Scanner is a tool that reads and decodes QR codes — two-dimensional barcodes that store information such as URLs, contact details, Wi-Fi credentials, and more. Our free online scanner allows you to decode any QR code or barcode instantly using your device's camera or by uploading an image.

How Does Our QR Code Reader Work?

Our scanner leverages advanced JavaScript libraries running entirely in your browser. When you point your camera at a QR code or upload an image, our engine analyzes the pixel data, identifies the code region, and decodes it within milliseconds — no server required.
