### Best Practices
1. **Check source PDF type**:
   - Native PDF (from Word/etc): Best results
   - Scanned PDF: Use OCR first
   - Image-based: Limited accuracy

2. **Formatting considerations**:
   - Complex layouts may shift
   - Fonts substitute if not installed
   - Tables may need adjustment
   - Headers/footers require review

### Quality Settings
| Setting | Result |
|---------|--------|
| **Exact** | Matches layout precisely, harder to edit |
| **Editable** | Optimized for editing, may shift layout |
| **Text only** | Plain text, no formatting |

### Common Issues
| Issue | Solution |
|-------|----------|
| Text as image | Run OCR before converting |
| Missing fonts | Embed or substitute fonts |
| Broken tables | Manually adjust in Word |
| Lost colors | Check color profile settings |
```
