QR Code Generator

You can generate QR codes for: Text (any plain text), URLs (website links), WiFi (network credentials), Phone numbers, and Email addresses. Each type has specific formatting requirements to ensure proper scanning.

Error correction levels (L, M, Q, H) determine how much damage the QR code can withstand while remaining scannable. L (7%) is for clean environments, M (15%) is standard, Q (25%) for moderate damage, and H (30%) for high damage tolerance.

For WiFi QR codes, use the format: WIFI:T:WPA;S:NetworkName;P:Password;; where T is security type (WPA/WEP/nopass), S is network name, and P is password. Leave password empty for open networks.

QR code capacity depends on version and error correction level. Version 40 (largest) can hold: 2,953 characters (numeric), 1,817 characters (alphanumeric), or 1,273 characters (binary). Larger data requires larger QR codes.

Yes! You can customize both foreground (QR code) and background colors. However, ensure sufficient contrast for reliable scanning. Dark QR codes on light backgrounds work best. Avoid using similar colors that might confuse scanners.

For printing, use at least 1 inch (25mm) per side for reliable scanning. Larger sizes are better for distance scanning. Consider your printing resolution and scanning distance when choosing size.

QR codes are not encrypted - anyone can scan and read the content. Don't use QR codes for passwords, personal data, or sensitive information. They're best for public information like URLs, contact details, or WiFi credentials.
