Select the appropriate size (100-500px), error correction level, and output format. Higher error correction allows scanning even when the code is partially damaged.

3

Generate and Download

Click "Generate QR Code" to create your code instantly. Download it in your preferred format (PNG, JPG, GIF, or SVG) for immediate use.

4

Test Your QR Code

Always test your QR code with multiple devices and scanning apps to ensure it works correctly before using it in production or printing.

🔧 Advanced Features

Quick Presets

Use our preset templates for common QR code types like URLs, emails, phone numbers, SMS, WiFi credentials, and vCards. These ensure proper formatting and compatibility.

Error Correction Levels

Choose from Low (7%), Medium (15%), Quartile (25%), or High (30%) error correction. Higher levels create larger codes but work even when damaged or partially obscured.

Multiple Formats

Export as PNG for general use, JPG for smaller files, GIF for web compatibility, or SVG for scalable vector graphics that maintain quality at any size.

QR Code Best Practices and Common Mistakes

✅ Best Practices

📏 Optimal Size and Placement

• Minimum 2cm x 2cm for printed materials
• At least 200x200px for digital displays
• Place at eye level or easily accessible locations
• Ensure adequate contrast with background

🎯 Clear Call-to-Action

• Add instructions like "Scan for menu" or "Scan to connect"
• Explain what happens after scanning
• Include your logo or branding nearby
• Provide alternative access methods

🧪 Testing and Validation

• Test with multiple devices and scanning apps
• Verify URLs work and are mobile-friendly
• Check scanning from different distances
• Ensure proper lighting conditions

❌ Common Mistakes to Avoid

📱 Poor Mobile Experience

• Linking to non-mobile-friendly websites
• Using broken or expired URLs
• Requiring app downloads without notice
• Linking to slow-loading pages

🎨 Design and Placement Issues

• Making QR codes too small to scan
• Poor contrast with background colors
• Placing codes in hard-to-reach locations
• Over-customizing and reducing readability

⚠️ Security and Privacy Concerns

• Using URL shorteners that hide destinations
• Not using HTTPS for secure content
• Linking to suspicious or malware sites
• Collecting personal data without disclosure

Technical Information and Security

🔧 How QR Codes Work

QR (Quick Response) codes are two-dimensional matrix barcodes that can store various types of data. They consist of black squares arranged on a white background, with three position markers in the corners for orientation detection.

Data Capacity

  • Numeric: Up to 7,089 characters
  • Alphanumeric: Up to 4,296 characters
  • Binary: Up to 2,953 bytes
  • Kanji: Up to 1,817 characters

Error Correction

QR codes use Reed-Solomon error correction, allowing them to remain readable even when up to 30% of the code is damaged or obscured. This makes them ideal for outdoor use and situations where wear and tear is expected.

🔒 Privacy and Security

Client-Side Generation

Our QR code generator processes your data securely. While we use a trusted external API for generation, your sensitive data is handled with care and not stored on our servers.

Security Best Practices

  • • Always use HTTPS URLs for sensitive content
  • • Avoid including passwords or sensitive data directly
  • • Use trusted QR code scanners to avoid malware
  • • Regularly update QR codes with dynamic content

Data Privacy

QR codes themselves don't track users, but the destinations they link to might. Always inform users about data collection and use privacy-respecting analytics when tracking QR code usage.

Frequently Asked Questions

Q: What's the difference between QR code error correction levels?

A: Error correction determines how much of the QR code can be damaged while still remaining scannable. Low (7%) is good for clean environments, Medium (15%) for general use, Quartile (25%) for outdoor use, and High (30%) for harsh conditions where damage is likely.

Q: Can I edit a QR code after creating it?

A: Static QR codes (like those generated by this tool) cannot be edited once created. To change the content, you need to generate a new QR code. Dynamic QR codes (available through specialized services) allow content updates but require ongoing service subscriptions.

Q: What's the best size for printed QR codes?

A: For print, QR codes should be at least 2cm x 2cm (about 0.8 inches). The scanning distance follows a 10:1 ratio - for every 10 units of distance, the QR code should be 1 unit in size. For business cards, 1.5-2cm works well; for posters, 5-10cm is recommended.

Q: Why won't my QR code scan properly?

A: Common issues include: too small size, poor contrast, damaged or dirty surface, wrong format encoding, or incompatible scanner app. Ensure good lighting, clean surface, and try different scanning apps. Test your QR code immediately after creation.

Q: Are QR codes secure for sensitive information?

A: QR codes themselves are not encrypted, so avoid including passwords, personal IDs, or sensitive data directly. Instead, link to secure websites (HTTPS) where users can safely enter sensitive information. For high-security applications, consider encrypted QR code solutions.

Q: Do QR codes expire?

A: Static QR codes (like ours) never expire - they permanently encode the data you specify. However, if they link to a website or service, that destination might become unavailable. Dynamic QR codes from paid services may expire if subscriptions lapse.

Q: Can I customize the appearance of QR codes?

A: While our basic generator creates standard black-and-white codes, you can customize colors, add logos, and modify designs using specialized tools. However, be cautious - too much customization can reduce scannability. Always test extensively after customization.

Q: What file format should I choose?

A: PNG is best for general use and print (lossless, transparent background support). JPG for smaller file sizes when transparency isn't needed. SVG for scalable graphics that maintain quality at any size (ideal for logos and large prints). GIF for basic web use and animations.
