Advanced Techniques for Power Users
1. Dual Numbering Systems
Use the pattern “Appx-A.{page}” to create separate numbering for appendices while maintaining the main document count.
2. Color Coding
Assign different colors to sections (e.g., blue for main content, red for appendices) using the RGB color picker.
3. Offset Mastery
Set the start page to “-5” to create placeholder pages that won’t be numbered in the final count.
4. Angle Positioning
Use 45° rotation with transparency for subtle watermark-style numbering that doesn’t obscure content.
5. Batch Processing
Process multiple documents simultaneously by opening the tool in separate browser tabs.
Frequently Asked Questions

Performance depends on your device, but most modern computers handle 100+ page PDFs.
