常见问题
What types of QR codes can I create?
You can encode a URL, free-form text, WiFi network credentials (SSID, password, encryption type), and contact cards in vCard format. Pick the type, fill in the fields, and the code updates instantly.
Is my data uploaded anywhere when I generate a code?
No. The QR code is rendered locally in your browser using JavaScript, so the URL, WiFi password, or contact details you enter never leave your device. That makes it safe for sensitive WiFi passwords.
Can I change the colours and size of the QR code?
Yes. You can set the foreground (dot) colour, the background colour, and the pixel size. Keep strong contrast (dark dots on a light background) so scanners read it reliably.
What file format do I get and can I print it?
You download a PNG raster image. For large-format printing such as posters or banners, generate at the largest available size so the code stays sharp when scaled up.
How do I make a QR code that connects people to my WiFi?
Choose the WiFi type, enter your network name (SSID), password, and encryption (usually WPA/WPA2). Scanning the resulting code prompts most phones to join the network without typing the password.
Why won't my QR code scan?
The usual causes are low colour contrast, too-small print size, or a very long URL packed into a tiny code. Use dark-on-light colours, increase the size, and shorten long links before encoding.
Do the QR codes expire or stop working?
No. These are static codes that encode your data directly, so they work forever and have no tracking or redirect server. The trade-off is you cannot edit the destination after printing.
Is there a limit on how many QR codes I can make?
Free use covers 5 generations per day with no signup. Pro at $19/month removes the daily limit if you need to batch many codes.
