❓ Frequently asked questions
Is the QR code generator really free?
Yes. Generating and downloading QR codes costs nothing — no signup, no trial, no watermark.
Do my QR codes expire or need an account?
No. The QR image is yours to keep — download the PNG and use it anywhere. No account, no subscription, nothing to renew.
Can I create a WiFi QR code?
Yes — paste a WiFi connection string (for example WIFI:T:WPA;S:MyNetwork;P:password;;) into the text field and generate. Scanning the code lets guests join your network without typing the password.
Is my data kept private?
Your text is sent to the free api.qrserver.com image service only to draw the QR code image. US AI itself stores nothing, so please don’t encode passwords or secrets you wouldn’t share.
What size and format can I download?
PNG, in 200px, 300px or 500px. Pick 500px for printed materials like posters, menus and business cards so the code scans cleanly.
Can I put a QR code on a business card or restaurant menu?
Absolutely. QR codes work great on business cards, restaurant menus, flyers and event tickets — link them to your website, menu or booking page.
