What types of content can I encode?

1. Click on "Add Logo (optional)"
2. Select an image file from your device
3. The logo will automatically be centered on your QR code
4. For best results, use a simple logo with good contrast

What do the error correction levels mean?

• Low (7%): Smallest size, least redundancy
• Medium (15%): Good balance (recommended)
• High (25%): Better for logos or damaged codes
• Maximum (30%): Most redundancy, largest size

Why isn't my QR code scanning properly?

• Ensure there's enough contrast between foreground and background colors
• Try increasing the error correction level
• Make sure your logo isn't covering too much of the QR code
• Test with different QR scanner apps

Why is my downloaded QR code blurry?

• Try generating a larger size (300x300 or higher)
• Download as SVG for vector format that scales perfectly
• Ensure your logo image is high resolution

Is there a limit to how much text I can encode?

Yes, QR codes have capacity limits based on their size and error correction level. We recommend keeping URLs under 300 characters and text content under 500 characters for reliable scanning.

Are my generated QR codes stored on your servers?

No, all QR code generation happens in your browser. We only store your recent codes locally in your browser's storage for your convenience (which you can clear anytime).

Can I use these QR codes commercially?

Yes, all QR codes generated with QR Genius are free to use for personal and commercial purposes without attribution.
