What does error correction do?

Higher error correction lets the QR code still scan even if part of it is dirty, damaged or covered by a logo, at the cost of a slightly denser code. Medium is a good default.

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

Yes. QR codes have a maximum capacity, and very long text may not fit. If it is too long the tool will let you know so you can shorten it.

Can I download the QR code?

Yes. You can download the generated code as a PNG image or a scalable SVG.

How do I make a QR code scan reliably?

Use dark modules on a plain light background, keep at least a four-module empty quiet zone, avoid stretching the image, and test the final printed or displayed code on more than one phone.

Error correction

Higher error correction lets the code still scan when it is scratched or partly covered, but makes the pattern denser.

About the QR Code Generator

A QR code is a scannable square barcode that stores text, a URL or other data. Phone cameras read them instantly, which makes them handy for links, Wi-Fi details, menus and business cards.

Enter any text or use a starter for a website, email, phone number or Wi-Fi network. Adjust the size, quiet zone, colours and error-correction level while the built-in readiness check flags risky contrast or spacing.

The code is generated in your browser and can be downloaded as a crisp PNG or a scalable SVG, with nothing uploaded to a server.
