📱 QR Code Generator

Create QR Codes for Any Purpose

QR (Quick Response) codes are two-dimensional barcodes that can store various types of information and be scanned instantly with any smartphone camera. This generator creates QR codes for URLs, text, contact information, WiFi networks, phone numbers, and more. Perfect for marketing, business cards, menus, event tickets, or any situation where you want to share information quickly and easily.

What Are QR Codes?

QR codes were invented in 1994 by a Japanese company to track automotive parts. Today, they're used worldwide for countless purposes. Unlike traditional barcodes that can only store about 20 characters, QR codes can store thousands of characters and various data types. They're scanned by pointing a smartphone camera at them - no special app needed on modern phones.

Types of QR Codes You Can Create

• URL/Website: Link directly to a website. Great for marketing materials, menus, or business cards
• Text: Store plain text messages, notes, or instructions
• Email: Pre-fill an email with recipient, subject, and message
• Phone: Store a phone number that can be dialed with one tap
• SMS: Pre-fill a text message with recipient and message
• WiFi: Share WiFi network credentials - scan to connect automatically

Common Use Cases

• Business Cards: Include a QR code linking to your website, LinkedIn, or contact information
• Restaurant Menus: Display QR codes on tables for contactless menu access
• Marketing Materials: Add QR codes to flyers, posters, or advertisements to drive traffic to websites
• Event Tickets: Generate unique QR codes for event entry or verification
• WiFi Sharing: Create QR codes for your WiFi network so guests can connect easily
• Product Information: Link to product pages, manuals, or reviews
• Social Media: Link to your social media profiles or specific posts

Best Practices for QR Codes

Size Matters: QR codes should be at least 2x2 cm (about 1 inch) for reliable scanning. Larger is better, especially for print materials.

Contrast is Key: Use high contrast colors (typically black on white) for best scanning reliability. Light colors or low contrast can cause scanning failures.

Test Before Printing: Always test your QR code with multiple devices before printing large quantities or using in important materials.

Error Correction: Higher error correction levels allow QR codes to work even if partially damaged or obscured, but increase code complexity.

Keep It Simple: Shorter URLs and simpler data create cleaner, easier-to-scan QR codes.

QR Code Security Considerations

Verify Before Scanning: Malicious QR codes can redirect to phishing sites or download malware. Only scan codes from trusted sources.

Check the URL: Before visiting a website from a QR code, check the URL preview on your phone to ensure it's legitimate.

Use HTTPS: When creating QR codes for websites, use HTTPS URLs to ensure secure connections.

Don't Overshare: Be cautious about what information you encode in QR codes, especially for public use.

Technical Details

QR codes use error correction to remain readable even if damaged. This generator allows you to choose error correction levels:

• Low (L): ~7% error correction - smallest code size
• Medium (M): ~15% error correction - balanced option
• Quartile (Q): ~25% error correction - good for print
• High (H): ~30% error correction - maximum reliability

Important Notes

All QR codes are generated locally in your browser - your data never leaves your device. You can download QR codes as PNG images for use in print or digital materials. For best results, test your QR codes with multiple devices and scanning apps before widespread use. This tool is for legitimate purposes only - do not create QR codes for malicious or illegal activities.
