Generate high-quality QR codes for text, URLs, WiFi, phone numbers, and vCard contacts.
Use a square transparent PNG. Set error correction to H (high) for best results.
• Error correction — L (7%), M (15%), Q (25%), H (30%). Higher levels tolerate more damage.
• WiFi QR — Scanning connects directly to the specified WiFi network.
• URL — The https:// prefix is added automatically when missing.
• vCard contact — Scanning saves the contact directly to the phone's address book (vCard 3.0).
• Logo overlay — Recommend error correction H (high) to keep the QR code scannable.
• Download — Export as PNG (raster) or SVG (vector, scales losslessly).
