Frequently asked questions

Will my QR code data be stored anywhere?

No, the QR code is generated locally in your browser and nothing you enter is sent to or stored on a server.

Can I customize the colors of my QR code?

Yes, you can set both the foreground and background colors before downloading the image.

Will a custom-colored QR code still scan correctly?

Generally yes, as long as there's enough contrast between the foreground and background colors; very low-contrast combinations can make scanning less reliable.

Is there a limit to how much text I can encode?

Longer text produces a denser code that may be harder to scan at small sizes.

Do I need an account to generate a QR code?

No, there's no sign-up required — just enter your text or link and download the result.
