Q. Will a centred logo break QR scanning?
QR codes tolerate up to 30% damage thanks to error correction. A centre logo up to 25% of the area scans fine — the generator auto-applies error-correction level H.
Q. How do I make a Wi-Fi QR?
Enter SSID, password, and security type (WPA/WPA2). Scanning it auto-connects on iOS and Android camera apps.
Q. PNG or SVG?
SVG (vector) for print — scales without quality loss. PNG (with transparency) is fine for screens and social.
Q. Does colour customisation break scanning?
High contrast between fg and bg is required. Avoid low-contrast pairs like yellow on white — stick with dark on light.
Q. Do you support dynamic QR codes?
No — static QRs only (content fixed after generation). Dynamic QRs need a paid service.
Q. Can I make a vCard contact QR?
Yes — name, phone, email, address, company → vCard QR. Scanning saves directly to the receiver's contacts.
