Frequently Asked Questions
What can I encode in a QR code?
You can encode website URLs, plain text, phone numbers, email addresses, Wi-Fi credentials, and more. The most common use is encoding a URL so people can scan and open a website instantly.
Are the QR codes free to use commercially?
Yes! All QR codes generated here are 100% free for personal and commercial use. No watermarks, no restrictions, no hidden fees.
Do QR codes expire?
Static QR codes (like ours) never expire. The data is encoded directly in the code pattern, so it works forever — as long as the URL or content you linked remains active.
What size should I print my QR code?
For reliable scanning, print your QR code at least 2cm × 2cm (about 0.8 inches). For scanning from a distance (like a poster), use at least 10cm × 10cm. Our 300×300px or 500×500px options work well for most uses.
