Frequently Asked Questions

What's the difference between this and the basic QR generator?

This advanced version uses server-side rendering for higher quality output, supports larger QR codes (up to 2048px), and provides professional-grade error correction. It's ideal for print materials, marketing campaigns, and high-resolution displays.

Can I use custom brand colors in my QR code?

Yes! You can customize both the QR pattern color and background color to match your brand identity. Ensure sufficient contrast (we recommend at least 3:1 ratio) for reliable scanning across different devices.

What size QR code should I generate for printing?

For business cards, use at least 512px. For posters and banners, use 1024px or larger. For billboards and large displays, use the maximum 2048px. Always test scanning from the expected viewing distance before mass printing.

How much data can I encode in a QR code?

QR codes can store up to 4,296 alphanumeric characters or 7,089 numeric characters. However, more data creates denser, more complex codes that may be harder to scan. For best results, keep URLs under 200 characters and use URL shorteners for longer links.
