Tips

Longer or more complex content produces denser QR codes — increase the size to improve scan reliability.
PNG/JPEG are exported via canvas; SVG download is not supported yet.
A larger margin improves scan success, especially on busy backgrounds or in print.
Keep high contrast between dark modules and a light background; avoid inverted colors that hurt scanning.
After generating, test-scan to verify the link works and the content is correct.

QR Code Generator FAQ

What can I put in a QR code?

Links, plain text, contact details, Wi-Fi credentials, and more. This generator encodes whatever text you enter.

Can I download the QR code?

Yes. Generate the code, then save it as an image for print, social media, or sharing.

Do QR codes expire?

No. A QR code simply encodes the data you entered, so it keeps working as long as the content is still valid (for a link, that means the target URL is still live).

Do you store the data in my QR code?

No. The code is generated in your browser, so the link or text you encode is never sent to us or stored.
