What is this Tool?
The QR Code Generator creates scannable QR codes for URLs, plain text, email addresses, and phone numbers instantly. QR codes (Quick Response codes) are 2D barcodes that smartphones can scan with their cameras to instantly open a URL, dial a phone number, send an email, or display text. They bridge the physical and digital worlds and have become ubiquitous in marketing, payments, restaurants, business cards, and public information systems.
Frequently Asked Questions
Q: Are QR codes free to use?
A: Yes, QR codes are completely free to create and use forever. There is no licensing fee. The QR code standard is open and can be read by any smartphone camera without any special app.
Q: How much data can a QR code store?
A: A standard QR code can store up to 3,000 alphanumeric characters or about 1,800 bytes. For most use cases (URLs, contact info, short messages), this is more than enough.
Q: Do QR codes expire?
A: Static QR codes (like the ones generated here) never expire. Dynamic QR codes — which can be edited after creation — may have expiry dates depending on the service. For a permanent, free solution, static QR codes are ideal.
Q: What size should I print a QR code?
A: For reliable scanning, print QR codes at a minimum of 2×2 cm (about 0.8 inches). For outdoor use or large formats, scale up proportionally. Always test scan after printing before mass production.
