About This Tool
This free online QR and barcode scanner tool lets you read any QR code or linear barcode using your device’s camera – instantly. Unlike mobile apps that require installation or desktop software that demands payment, our tool works entirely in your web browser. Whether you need to scan a product barcode, a Wi-Fi QR code, a vCard contact card, or a URL, this tool decodes it in milliseconds.
Built with privacy as the core principle, all scanning happens locally on your device. Nothing is sent to any server, no images are uploaded, and no data is logged. This makes it perfect for scanning sensitive information like payment addresses, authentication codes, or personal documents.
The tool supports all major barcode formats including QR Code, UPC (products), EAN (retail), Code 128 (shipping), Code 39 (inventory), and many more. Works on desktop, tablet, and mobile – any device with a camera and a modern browser.
