How to Create a Free QR Code That Never Expires

Why QR codes "expire"

A QR code itself never expires — it is just a 2D barcode encoding a string. What expires is the destination URL if you use a redirect service that shuts down, pays-walls, or rate-limits after a trial period. To create a QR code that truly never expires:

Use a static QR code (not a dynamic/redirect one).
Encode a URL you control (your own domain or a stable permalink).
Avoid URL shorteners with expiration policies.

Wi-Fi QR code format explained

The Wi-Fi QR format WIFI:T:<auth>;S:<ssid>;P:<password>;H:<hidden>; is a de-facto standard recognized by Android and iOS camera apps:

T — Authentication type: WEP, WPA, or nopass
S — Network SSID (escape \;, \,, \", \\)
P — Password (same escaping rules)
H — Hidden network: true or omitted

Best practices

Use error correction level M (15%) for general use, H (30%) for print.
Minimum size: 2×2 cm for screen, 3×3 cm for print at 30 cm distance.
Keep quiet zone (margin) at least 4 modules wide.
Test with multiple scanner apps before deploying.
