Yes, completely. QR codes generated here have no watermark, no expiry date, and no usage restrictions. You can use them for business cards, menus, marketing materials, or any other purpose.
How do I create a WiFi QR code?
Select the WiFi tab, enter your network name (SSID) and password, choose your security type (WPA2 is most common), and click Generate. Anyone who scans the code will be automatically connected to your WiFi network without typing the password.
What size QR code should I use for printing?
For business cards use 256px minimum. For posters or flyers use 512px or 1024px. As a general rule, the QR code should be at least 2cm × 2cm when printed to be reliably scannable by a smartphone camera.
Do the QR codes expire?
No. The QR codes generated here are static — they encode the information directly and will work forever as long as the destination URL remains active. There is no server or account involved.
