Frequently asked questions

What can I encode in a QR code?
You can encode any text: URLs, email addresses, phone numbers, WiFi credentials, plain text, and more. The maximum capacity is about 2,048 characters.
Which error correction level should I use?
Use M (15%) for most cases. Use H (30%) if the QR code will be printed on materials that may get damaged, or if you plan to add a logo overlay.
Will the QR code work with custom colors?
Yes, but ensure good contrast between foreground and background colors. Dark foreground on light background works best. Avoid very light foreground colors.
