QR code tips

FAQ

Do these QR codes expire?

No. The content is encoded directly in the code — there’s no short link or redirect through our servers, so it keeps working forever.

How do Wi-Fi QR codes work?

Enter the network name, password and security type. Scanning with a phone camera joins the network without typing the password.

PNG or SVG?

SVG for print — it scales to any size without blurring. PNG for websites, documents and messaging apps.

Why won’t my QR code scan?

Keep a white margin around it, print it at least 2 cm wide, and keep strong contrast between code and background. Raise error correction to Q or H if it may get damaged or partly covered.

Is my data stored?

No. Everything happens in your browser; nothing you type is sent anywhere.

Can I use the QR codes commercially?

Yes, free for any use. QR Code is a registered trademark of DENSO WAVE.
