Frequently Asked Questions
What can I put in a QR code?
URLs, plain text, WiFi credentials (WIFI:T:WPA;S:name;P:pass;;), email addresses, and contact cards — up to a few thousand characters.
Do QR codes expire?
Codes made here are static — the pattern encodes your text directly, so it works forever with no service in the middle.
Why won't my QR code scan?
Usually low contrast, too small in print, or an over-long payload. Regenerate at Large size and keep good light/dark contrast.
Is my data uploaded anywhere?
No — generation happens 100% in your browser via JavaScript.
Can I use the codes commercially?
Yes — menus, packaging, ads, signage. No watermark, no attribution required.
