- What is QR Code Generator best for?
- Generate QR codes from any text, URLs, contact information, or other data quickly.
- Does QR Code Generator upload or store my data?
- This text tool is local-first in the browser and does not store your input for normal conversion workflows.
- What's the maximum data length for a QR code?
- The capacity depends on error correction level and character type. Numeric only: up to 7089 digits. Alphanumeric: up to 4296 characters. For larger data, consider using a URL shortener or splitting into multiple QR codes.
- How do I choose the right error correction level?
- L (7% recovery) for clean, static placements. M (15%) for general use. Q (25%) for outdoor or medium-distanced scanning. H (30%) for industrial settings or small codes. Higher levels increase QR size.
- Why can't some QR code readers scan my generated QR code?
- Check: insufficient quiet zone (white border), too much data for the size, print resolution too low, or error correction level too low. Test with multiple scanner apps before finalizing.
- Can I customize the QR code colors?
- Yes. You can set foreground and background colors. Ensure sufficient contrast (dark on light or light on dark). Avoid red on red-green colorblind-friendly designs. Test with actual scanner apps.
- Which tools pair well with QR Code Generator?
- Common next steps include QR Code Parser, Google Authenticator QR Converter. These related tools help continue the same workflow through generation, validation, formatting, or debugging.
