The codes made here are static: the text is inside the image, so they never expire and don't depend on any website. WhatsApp numbers go in full international format with no plus sign, spaces or leading zero. Test-scan with two phones before printing, and keep dark modules on a light background.

Questions people ask
Do these QR codes expire?+
No. These are static QR codes: the link or text is stored inside the code itself, so it works for as long as the link works. There is no redirect, no tracking and no subscription.
Can I use the QR code on printed menus, flyers or products?+
Yes, free for personal and commercial use. For print, download the SVG (it stays sharp at any size) or a PNG of 1024 px or more, and test-scan it before printing.
How does a Wi-Fi QR code work?+
Guests point their phone camera at it and tap the pop-up to join your network without typing the password. It works with the built-in camera on iPhone (iOS 11 and later) and Android 10 and later.
Why won't my QR code scan?+
Usually the colours are too light or too close together, the code is printed too small (keep it at least 2 × 2 cm), or there is too much text in it. Use dark dots on a light background and keep the white border around the code.
