How to make a QR code
- Choose what the code should open: a website, Wi-Fi, a WhatsApp chat, a phone number, an email or a contact card.
- Fill in the details. The code updates as you type.
- Download it as PNG for printing and sharing, or SVG for any size without blur.
Wi-Fi QR codes
Print one for your shop, office or guests. They point their camera at it and join without typing the password.
Printing tips
- Print at least 2 × 2 cm, bigger if people scan from far away.
- Keep dark dots on a light background with strong contrast.
- Use Highest error correction for print that might get dirty or scratched.
- Always test with a phone before printing many copies.
Do these codes expire?
No. They hold your information directly, with no redirect service, so they work forever and nobody tracks scans.
