What is a QR Code Generator?
A QR code generator is a digital tool that creates Quick Response (QR) codes from various types of data including URLs, text, contact information, and Wi-Fi credentials. QR codes are two-dimensional barcodes that can be quickly scanned by smartphones and other devices to instantly access the encoded information.
Our free online QR code generator supports multiple data types and formats, allowing you to create QR codes for websites, Wi-Fi networks, contact cards (vCard), and plain text. The generated QR codes are compatible with all modern QR code scanners and can be customized with different error correction levels and sizes to suit your specific needs.
Whether you're sharing a website URL, providing Wi-Fi access to guests, distributing contact information, or encoding any text message, our QR code generator provides a fast, reliable, and user-friendly solution. All QR codes are generated locally in your browser, ensuring your data remains private and secure.
Common Uses for QR Codes
Business and Marketing
Use QR codes on business cards, flyers, posters, and advertisements to direct customers to your website, social media profiles, or promotional content. QR codes make it easy for customers to access your digital presence without typing long URLs, improving engagement and conversion rates.
Wi-Fi Sharing
Generate Wi-Fi QR codes to allow guests, customers, or visitors to connect to your network instantly without manually entering complex passwords. Simply display the QR code and let users scan it to connect automatically to your Wi-Fi network.
Contact Information
Create contact QR codes (vCard format) that contain your name, phone number, email, website, and address. When scanned, these QR codes allow people to save your contact information directly to their phone's address book with a single scan.
Event Management
Use QR codes for event tickets, registration, check-ins, and information sharing. QR codes can contain event details, venue information, or links to event websites, making event management more efficient and providing attendees with quick access to important information.

Frequently Asked Questions
What types of QR codes can I generate?
Our QR code generator supports four main types: URL/website links, plain text messages, Wi-Fi network credentials (SSID, password, security type), and contact information in vCard format (name, phone, email, address, organization). Each type is optimized for its specific use case and follows industry standards for maximum compatibility.
Are the generated QR codes free to use?
Yes, all QR codes generated using our tool are completely free to use for personal and commercial purposes. There are no restrictions, watermarks, or limitations on the QR codes you create. You can use them in marketing materials, business cards, websites, or any other application without any licensing fees or attribution requirements.
What is error correction in QR codes?
Error correction allows QR codes to remain scannable even if they are partially damaged, dirty, or obscured. Our generator offers four levels: Low (7% recovery), Medium (15% recovery), Quartile (25% recovery), and High (30% recovery). Higher error correction levels make QR codes more robust but also larger and more complex. Medium level is recommended for most use cases.
How do Wi-Fi QR codes work?
Wi-Fi QR codes encode network credentials in a standardized format that smartphones can recognize. When scanned, the device automatically prompts to connect to the Wi-Fi network without manually entering the password. The QR code contains the network name (SSID), password, security type (WPA/WEP/Open), and whether the network is hidden. This works on most modern Android and iOS devices.
Is my data secure when generating QR codes?
Yes, your data is completely secure. All QR code generation happens locally in your browser using JavaScript - no information is transmitted to our servers or stored anywhere. Your URLs, Wi-Fi passwords, contact information, and text remain private on your device. The QR codes are generated client-side and you have full control over the data at all times.
