Frequently Asked Questions

Will custom colors make the QR code unscannable?

High-contrast color choices scan fine; very light or low-contrast foreground/background combinations can reduce scan reliability, so keep contrast strong.

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

Longer text produces a denser QR code with more modules - very long strings (paragraphs) will still work but may be harder to scan from a distance; short URLs work best.

Does the QR code expire?

No - since it directly encodes your content (not a shortened redirect link), it works forever and isn't tied to any account or service.
