How to Generate a QR Code
QR codes are two-dimensional barcodes that can store URLs, text, contact information, and more. Our generator creates QR codes entirely in your browser —no data is ever sent to a server.
Step-by-Step Guide
- Select the QR type —Choose from URL, text, email, phone number, or Wi-Fi network.
- Enter your data —Type or paste the URL, text, or contact info you want to encode.
- Customize —Adjust the size (150-600px) and choose a color for your QR code.
- Generate —Click the "Generate QR Code" button.
- Download —Save the QR code as a high-quality PNG image.
QR Code Types Explained
- URL —Create QR codes that open websites when scanned. Perfect for marketing materials, business cards, and menus.
- Plain Text —Encode any text message. Useful for sharing Wi-Fi passwords, instructions, or short notes.
- Email —Generate a QR code that opens the user's email app with a pre-filled address.
- Phone Number —Create a QR code that prompts the user to call a specific number.
- Wi-Fi Network —Generate a QR code that lets guests connect to your Wi-Fi without typing the password.
Best Practices for QR Codes
- Size matters —For print, ensure the QR code is at least 2cm × 2cm (about 1 inch). For digital use, 200-300px is usually sufficient.
- Contrast is key —Use dark colors on a white or light background. Low contrast QR codes are difficult to scan.
- Test before printing —Always scan your QR code with a phone before mass-producing or distributing it.
- Short URLs are better —Shorter URLs produce simpler, more scannable QR codes. Consider using a URL shortener for long links.
Technical Details
Our QR code generator uses a pure JavaScript implementation that builds QR codes as HTML5 Canvas elements. The algorithm follows the QR code standard (ISO/IEC 18004) and supports automatic error correction level M (15% recovery).
Frequently Asked Questions
Yes, completely free with no limits. Generate as many QR codes as you need, at any size, with any color.
No. The QR code is generated entirely in your browser using client-side JavaScript. The URL or text you enter never leaves your device.
Yes! Use the color picker to choose any color for your QR code. For best scanning results, use dark colors on a white or very light background.
Static QR codes (which our tool generates) never expire —the encoded data is part of the pattern itself. However, if you encode a URL that later becomes unavailable, the QR code will still "work" but lead to a dead link.
