Advanced Tips and Design Suggestions

Suggestions for making high-quality QR codes:

Design Points

1. Color Contrast Ensure foreground and background colors have clear contrast, otherwise affects scanning recognition.

3. Size Selection

• Screen display: 200x200 pixels sufficient
• Printing use: suggest 300x300 or above

4. Test Verification After generation, must test scan with phone to ensure proper recognition.

Content Optimization

URL Optimization:

• Use short links (like bit.ly)
• Simplify URL structure
• Avoid overly long URLs

Error Correction Level: QR codes support different correction levels:

• Level L: 7% correction (maximum capacity)
• Level M: 15% correction (recommended)
• Level Q: 25% correction
• Level H: 30% correction (recommended for Logo embedding)

Batch Usage Tips

For batch generation:

• Generate one by one then save with unified naming
• Use fixed style template for consistency
• Keep generation records to avoid duplicates
