QR Code Generator
The QR code generator creates a scannable QR code for a link, plain text or a Wi-Fi network. Choose the size, colors and error correction, then download it as a PNG or a sharp SVG. The code is drawn in your browser, it never expires, and there is no sign-up or watermark.
How to make a QR code that scans well
- Keep strong contrast: a dark code on a light background scans best. Avoid light-on-dark inverted codes, which many readers cannot scan.
- Leave the quiet zone. The white border of at least 4 modules helps scanners find the code.
- Shorter content makes a simpler, bigger-dotted code. Use a short link where you can.
- Test the printed code with a phone before you print hundreds.
Error correction levels
| Level | Recovers | Best for |
|---|---|---|
| Low | About 7% | Clean screens, small codes |
| Medium | About 15% | General use |
| Quartile | About 25% | Printed codes that may get scuffed |
| High | About 30% | Rough surfaces, logos placed over the code |
This generator makes static QR codes. The data is built into the pattern itself, so the code works forever and never depends on our site. Anyone who scans a Wi-Fi code can join your network, so only share it where you are happy for people to connect.
Questions people ask
Do these QR codes expire?
No. A static code contains the data itself, so it works as long as the link or content it holds is still valid.
Is it free to use commercially?
Yes. You can print and use the codes you create anywhere, with no watermark or tracking.
PNG or SVG?
Use PNG for web and documents. Use SVG when you need the code to stay sharp at any size, such as on posters or packaging.
