About QR Code Scanner
QR Code Scanner is a powerful client-side tool that instantly decodes QR codes using your device camera or uploaded images. It supports all standard QR code formats including URLs, plain text, email addresses, phone numbers, SMS messages, Wi-Fi credentials, vCard contacts, and geographic locations. QR codes store information in a grid of black and white modules. When scanned, the scanner detects position patterns in three corners, or upload an image file—the scanner analyzes it and decodes any QR code found. For maximum compatibility, the scanner tries multiple detection strategies: direct scan, inversion attempt, contrast enhancement, and image scaling. The tool automatically detects the QR code type and displays the content appropriately—URLs can be opened directly, phone numbers can be called, Wi-Fi credentials can be used to connect, and contacts can be added to your address book. A scan history is maintained locally in your browser, showing the last 50 scans with timestamps and type detection for easy reference. All QR code scanning happens entirely in your browser—no images or decoded data are sent to servers, ensuring complete privacy. Camera access requires HTTPS or localhost, and works in modern browsers like Chrome, Firefox, Safari, and Edge. Perfect for quickly accessing information from QR codes on products, business cards, flyers, documents, event tickets, and marketing materials. Scan Wi-Fi QR codes to connect to networks without typing passwords, scan contact QR codes to add people to your address book, open website links from printed materials, decode text from QR codes in documents, and access payment links or cryptocurrency addresses. Use this tool to instantly decode any QR code you encounter—whether via camera scan or image upload—with support for all standard QR code formats.
