What can I encode in a QR code?

You can encode URLs, plain text, email addresses (mailto:), phone numbers (tel:), WiFi credentials, and vCard contact information. Any smartphone camera can scan and decode these.

What is error correction level?

Error correction allows a QR code to be scanned even if part of it is damaged or obscured. Level L (7%) is minimal, M (15%) is standard, Q (25%) is high, and H (30%) is maximum — use H if you plan to add a logo over the QR code.

Can I use custom colors?

Yes. You can set any foreground (dark) and background (light) color. Make sure there is sufficient contrast — the dark color should be significantly darker than the background for reliable scanning.

Are QR codes generated here free to use commercially?

Yes. QR codes are an open standard and the ones you generate here have no license restrictions. Use them for personal or commercial purposes freely.
