QR design tips

Use strong contrast

Dark QR dots on a light background are usually the most dependable.

Keep some clear space

A quiet zone around the QR helps phone cameras separate the code from surrounding artwork.

Keep logos modest

A very large logo can cover too much data. Use High error correction when a logo is included.

Size for the viewing distance

Small cards can use compact codes; posters need larger printed QR codes for comfortable scanning.

Questions

Frequently asked questions

Is this QR Code Generator free?

Yes. You can create static QR codes without creating an account. The QR is generated in your browser.

Can I use my own logo and colors?

Yes. Upload a logo and choose foreground and background colors. Keep enough contrast and avoid making the logo too large.

Can I download the QR in PNG and PDF?

Yes. PNG is useful for websites, social media and documents. PDF is convenient for print workflows.

Does the QR code expire?

The QR codes created by this tool are static and do not have an ALT4 expiry date. If a QR points to an external URL, that destination still needs to remain available.

Can I edit a QR after printing it?

A static QR permanently contains the data that was encoded when it was created. To change that data, generate a new QR code and replace the printed code.

Why should I leave spacing around a QR code?

Clear space, often called the quiet zone, makes it easier for scanners to identify the boundary of the QR code. Avoid placing text or graphics too close to it.
