How to Generate QR Codes
Step 1: Choose Your Content Type
Decide what you want to encode: URL, text, email, phone number, or WiFi credentials. Our QR Code Generator supports all these types.
Step 2: Enter Your Data
Enter the information you want to encode. For URLs, make sure to include the full address (https://). For text, you can enter up to several hundred characters.
Pro Tip: For URLs, always use HTTPS for security. Short URLs work better for QR codes as they create simpler patterns.
Step 3: Customize (Optional)
While our basic generator creates standard QR codes, you can customize colors and sizes in advanced tools. However, be careful with customization as it can affect scannability.
Step 4: Download and Use
Download your QR code as PNG or SVG. Use it in print materials, websites, presentations, or social media.
Best Practices
Test Before Printing
Always test your QR code with multiple devices before printing or publishing. Ensure it scans quickly and accurately.
Size Matters
Make QR codes large enough to scan easily. Minimum recommended size is 2cm x 2cm (0.8" x 0.8") for print.
Add Error Correction
Higher error correction levels allow QR codes to work even if partially damaged or obscured.
Provide Context
Add text near your QR code explaining what it does. This helps users understand what they'll access.
