How to make a QR code
- Choose what the code should do: open a link, join Wi-Fi, show text, write an email, call or text.
- Fill in the details. The QR code updates instantly.
- Pick colours and a size, then Download PNG (for screens and documents) or SVG (sharp at any print size).
- Scan it with your phone camera to test.
Wi-Fi QR code for guests
Choose Wi-Fi network, enter the network name and password, and print the code for your fridge, Airbnb or café counter. iPhone and Android cameras join the network in one tap, with no typing of long passwords. Your password stays on your device; it is not uploaded.
Printing tips
| Use | Minimum printed size | Tip |
|---|---|---|
| Business card | 2 × 2 cm (0.8 in) | Keep the URL short |
| Flyer / menu | 3 × 3 cm (1.2 in) | Use Medium error correction |
| Poster / window | 10 cm+ (4 in+) | Rule of thumb: scan distance ÷ 10 |
Want to add a logo in the middle? Choose High error correction so the code still scans with part of it covered, and keep the logo small.
QR Code Generator FAQs
Is this QR code generator really free?
Yes. There is no sign-up, no watermark, no scan limit and no expiry. The QR code is created in your browser.
Do these QR codes expire?
No. They are static QR codes, so the link or text is stored inside the code itself. They work as long as the link they point to works.
How do I make a QR code for Wi-Fi?
Choose Wi-Fi network, type the network name and password, pick the security type (usually WPA), then download the code. Guests scan it to join.
PNG or SVG — which should I download?
PNG is best for websites, documents and social media. SVG is a vector file that stays sharp at any size, so it is best for print.
