QR Code Generation FAQ
What is the optimal Error Correction Level?
For standard URLs or text codes, Medium (M, 15% recovery) provides the best balance between scan speed and physical durability. If printing on textured materials or outdoors, consider high settings (H, 30% recovery) for optimal device scanning.
Are my inputs stored on a server?
No! Unlike standard generators that route conversion logic to background APIs, CodeToolTip generates the entire QR code locally via your browser's rendering engine. Absolutely zero data leaves your local machine.
Quick Tips
- Ensure high contrast between foreground and background colors for faster scanning.
- Medium (M) error correction is standard and provides fast scans.
- Generate scalable SVGs for printing or high-DPI displays.
- Slightly increase error correction to High (H) if you plan on adding overlay logos later.
