How to use it (step-by-step)

- Customize the Format (example:
Page {n} of {N}). - Tick Skip first page if your cover shouldn’t be numbered.

Tips & good practices
- For formal documents, use a consistent margin (e.g., 36–54 pts) and center alignment.
- Long reports often use bottom-center numbering for readability.
- When you need to combine files, first merge them, then number once at the end to keep counts correct. Try our Free Online PDF Merger.
- Securing the final PDF? Apply a password with our Free Online PDF Encryptor.
Pros
- Private: everything runs locally in your browser.
- Free & fast: no watermarks, no upload delays.
- Flexible formatting: “{n}”, “{N}”, custom start number, and alignment.

Considerations
- Very large PDFs depend on your browser’s memory. If it’s huge, try processing section by section or optimizing images first with our Free Image Compressor & Resizer.
- If your file is password-protected, unlock it first using Online Free PDF Password Remover (use only on files you’re authorized to open).
Common numbering formats you can use
{n}→ 1, 2, 3 …Page {n} of {N}→ Page 1 of 12{n}/{N}→ 1/12Sec {n}→ Sec 1 (for informal sections)
Frequently Asked Questions
Does this upload my PDF?

Can I skip numbering on the first page?
Yes. Enable Skip first page before exporting.
How do I add “Page 1 of 20” style numbers?
Use the format Page {n} of {N}. The tool replaces the placeholders automatically.
