Frequently asked questions
- Can I put a logo in the center of a QR code?
- Yes. Upload your logo and it will be placed in the center. Use High (H) error correction to ensure the QR code remains scannable even with the logo covering part of the data pattern.
- What data can I encode in a QR code?
- URLs, plain text, WiFi credentials, vCard contact info, email addresses, phone numbers, and more. The QR code stores any text data up to about 4,000 characters.
- Will a colored QR code still scan?
- Yes, as long as there is sufficient contrast between the foreground and background. Dark foreground on light background works best. Avoid light-on-dark unless you are sure your scanner app supports it.
