How to Add Page Numbers to a PDF

You've assembled a 30-page PDF report — chapters from different sources, sections written by different people. And nobody numbered the pages. Now someone references "the third point on page 14" and you're scrolling endlessly trying to find it.

Page numbers are a small thing that make a big difference. Here's how to add them to any PDF for free.

How to add page numbers to a PDF

1. Open the Add Page Numbers tool
2. Upload your PDF
3. Choose your position (bottom center, bottom right, top right, etc.)
4. Set a starting page number if needed (e.g. start at 1, or start at 5 for documents with a cover page)
5. Click Add Page Numbers
6. Download your numbered PDF

Where should page numbers go?

There's no universal rule, but conventions vary by document type:

• Academic papers & reports — bottom center or bottom right is standard
• Business documents — bottom right is common
• Books and long-form documents — alternating left/right (odd pages right, even pages left) for print, but bottom center for digital

For most digital documents, bottom center is a safe, clean default that works well.

Should I number the cover page?

Usually not. A common approach is to start numbering from page 2 or 3 (after the cover and table of contents) but display the number as "1" for the first body page. This is called a "page offset" — you tell the tool to start counting at a different number than 1.

If your document has a cover page and a table of contents, set the start number so that page 3 (the first content page) shows as "1".

What if my PDF already has page numbers?

If the existing numbers are baked into the content (part of the original document design), they'll remain. The tool adds new numbers as a separate overlay — they won't replace content that's already there. If you need to remove existing page numbers, that's a more complex editing task.

Other ways to organise a PDF

Once your document is numbered, a few other tools can help organise it further:

• Merge PDF — combine multiple documents into one before adding page numbers
• Split PDF — extract specific pages or sections
• Rotate PDF — fix any pages that are upside down or sideways before finalising

Adding page numbers is a finishing touch that makes any document feel more professional. It takes seconds — and saves minutes of confusion for everyone who reads it.
