Frequently Asked Questions
Can I add my company logo to QR codes without affecting scannability?
Yes! Our enhanced QR generator intelligently embeds logos while maintaining scannability. We recommend using 'High' error correction (30%) when adding logos, and keeping logo size under 20% of the total QR code area. The system automatically adds background padding and optimizes logo placement for maximum reliability across different scanners and devices.
What's the difference between gradient and solid color QR codes?
Gradient QR codes use smooth color transitions for visual appeal, perfect for marketing materials and branded content. You can customize gradient direction (0-360°) and choose any start/end colors. Solid color QR codes use single colors for maximum contrast and reliability. Both formats maintain full scanning compatibility when proper contrast ratios are maintained between foreground and background colors.
Which error correction level should I choose for professional applications?
For professional use: 'Medium' (15%) for basic QR codes, 'Quartile' (25%) for codes with small design elements, and 'High' (30%) for codes with logos or outdoor use. Higher error correction allows up to 30% of the QR code to be damaged while remaining scannable, essential for codes with embedded logos, printed materials, or harsh environments.
What file formats and sizes work best for logo uploads?
Upload logos in PNG, JPG, or SVG format for best results. PNG is recommended for logos with transparency. Keep logo files under 2MB and use square or circular designs for optimal appearance. The system automatically resizes and positions logos, but starting with high-resolution images (at least 200x200px) ensures crisp output at all QR code sizes.
How do I ensure my custom QR codes work reliably across different devices?
Follow these best practices: maintain high contrast between colors, test with multiple QR scanner apps, use 'High' error correction for styled codes, ensure minimum 2x2cm print size, and avoid very light colors on white backgrounds. Our generator automatically validates color contrast and provides warnings for combinations that might reduce scannability.
