About Our Free QR Code Generator
A QR code (Quick Response code) is a type of two-dimensional barcode that stores information in a compact and scannable format. Whether you’re a business owner, teacher, student, or event organizer, QR codes provide a simple way to share data with a single scan using a smartphone.
At calmath.info, our free QR Code Generator lets you create custom QR codes for any content — including URLs, phone numbers, plain text, Wi-Fi credentials, and more. No registration or software is required. Just enter your data, click “Generate,” and your QR code appears instantly on screen.
Once generated, you can download your QR code image and embed it in flyers, business cards, restaurant menus, product labels, or digital campaigns. QR codes are commonly used in mobile marketing, education, event management, and payment systems like QR-based bank transactions.
