Frequently Asked Questions
- What types of data can a QR code store?
- QR codes can store URLs, plain text, phone numbers, email addresses, SMS messages, WiFi network credentials, vCard contact information, location coordinates, and calendar events. The maximum capacity is around 3000 characters — smaller data produces simpler codes that scan faster and more reliably.
- What is error correction and which level should I choose?
- Error correction allows a QR code to be scanned even if part of it is damaged or obscured. Level L (7% recovery) works for clean digital-only use. Level M (15%) is standard for most print materials. Level Q or H (25–30%) is needed when you want to overlay a logo in the center of the code.
- How large should a QR code be when printed?
- The minimum recommended print size is 2×2 cm for a QR code scanned at arm's length. For signage, posters, or packaging scanned from further away, scale up proportionally — a code scanned from 1 meter needs at least 4×4 cm. Always test-scan before printing a large batch.
- Can I edit a QR code after creating it?
- No — a QR code's content is permanently encoded in its pattern. If the URL or information changes, you must generate a new code and update any materials that use it. For links that change frequently, use a URL shortener that redirects to any destination — you can update the destination without replacing the QR code.
