FAQ
What if it doesn't scan?
Adjust error correction (ECC) and margin. Increasing the margin usually improves reliability, and higher ECC helps when the code may get damaged.
Is there a character limit?
The limit varies by content type, but longer input makes the QR denser and harder to scan. This tool shows warnings for long input.
Can I generate Wi‑Fi QR codes?
It can be added. A Wi‑Fi mode with SSID/password fields makes one‑tap connections easier (planned).
