Frequently Asked Questions

What data can be encoded?

URLs, plain text, contact info (vCard), WiFi credentials, email addresses, phone numbers, SMS, and more.

Can I add my logo to the QR code?

Yes, logos can be embedded in the center of QR codes with sufficient error correction to maintain scannability.

What size should QR codes be?

For printed materials, minimum 2x2 cm (0.8x0.8 in). For digital use, at least 200x200 pixels for reliable scanning.

What are error correction levels?

Higher error correction allows QR codes to remain scannable even if partially damaged or obscured, but increases size.

Can I change QR code colors?

Yes, but maintain high contrast between foreground and background for reliable scanning. Dark on light works best.
