How do QR codes work?
A QR code stores your text or link as a pattern of squares that any phone camera can read. Point the camera at the code and the link opens — no app needed on modern phones.
- Links: include the full address with https:// so every phone opens it correctly.
- Text: any text works — WiFi passwords for guests, a message, an email address.
- Printing: use the Large size for posters and banners; Small is fine for documents.
The QR image is generated by a free open API (qrserver.com). Test your printed code with two different phones before printing hundreds of copies.

Frequently Asked Questions
Is this QR generator really free?
Yes - generate and download as many codes as you want. No signup, no watermark.
Do the QR codes expire?
No. The code is just your text drawn as a pattern - it works forever. Only the link inside it can stop working if that website changes.
Can I scan a QR code without an app?
Yes - modern Android and iPhone cameras scan QR codes directly. Just open the camera and point it at the code.
How much text fits in a QR code?
Up to about 900 characters here. Shorter is better - short links make simpler codes that scan faster from farther away.
