About QR Codes

QR (Quick Response) codes are two-dimensional barcodes that can store various types of information:

  • Text: Simple messages or notes
  • URLs: Direct links to websites
  • Contact information: Phone numbers, email addresses, or full vCards
  • Wi-Fi credentials: Network names and passwords

The error correction level determines how much of the QR code can be damaged or obscured while still remaining scannable.

FAQ Frequently Asked Questions

What types of content can I encode in a QR code?
You can create QR codes for website URLs, plain text, email addresses, phone numbers, WiFi credentials, social media profiles, contact information (vCard), and even SMS messages. The tool automatically optimizes the QR code based on your content type.
Will my QR codes work on all smartphones?
Yes, modern smartphones (iPhone and Android) have built-in QR code readers in their camera apps. Older devices may need a dedicated QR scanner app, but the codes themselves are universally compatible and follow international standards.
How do I know what size QR code to use?
For business cards and close-up scanning, use smaller sizes (1-2 inches). For posters or signage where people scan from a distance, use larger sizes (4+ inches). The rule of thumb is: scanning distance should be about 10 times the QR code width.
Do QR codes expire or stop working?
The QR codes themselves never expire - they are just encoded information. However, if you encode a URL, that link could become inactive if the website goes down. For permanent content like text or contact info, the codes work indefinitely.
Is there a limit to how much text I can encode?
Standard QR codes can hold up to about 4,000 alphanumeric characters, but for best scanning reliability, keep content under 300 characters. Longer content creates more complex codes that are harder to scan, especially on mobile devices.
