📝 What Content Can You Encode?
QR codes can store various types of information. Here are the most common use cases:
Website URLs
Direct users to any website, landing page, or online resource. Perfect for marketing materials.
WiFi Networks
Share WiFi credentials instantly. Users can connect without typing passwords.
Contact Information
vCard format for business cards. Save contacts directly to phone with one scan.
Plain Text
Any text message, notes, or information. Great for sharing quick details.
Geographic Locations
GPS coordinates or Google Maps links for navigation and location sharing.
Email Addresses
Pre-filled email composition with subject and body text.
💡 Professional Tips for Perfect QR Codes
Use High Contrast Colors
Dark foreground on light background works best. Avoid similar colors like light blue on white.
Test Multiple Devices
Always test with different phones and scanning apps before printing or publishing.
Maintain Quiet Zone
Keep at least 4 modules (white squares) of empty space around the QR code.
Choose Right Size
Minimum 1x1 inch for print, larger for distance scanning. Consider viewing distance.
Keep Content Concise
Shorter URLs create less dense QR codes that scan faster and more reliably.
Use Error Correction
Higher levels (M, Q, H) for codes that might get damaged or printed on rough surfaces.
