How to Add Page Numbers to a PDF
Updated July 13, 2026
A PDF without page numbers is fine on a screen, but hand someone a printed copy and “see page 12” stops meaning anything. Here’s how to number every page for free, without uploading the file.
Steps
- Open Add Page Numbers and drop your PDF.
- Choose a position — any corner or the center of the top or bottom margin (bottom center is the default) — and a format: a plain number, “3 / 10”, or “Page 3 of 10”.
- Set a starting number if the document doesn’t begin at page 1.
- Click Add page numbers, then download.
The numbers are drawn directly into the saved PDF, so they display consistently in every reader — not just the one you used to add them.
When to set a custom starting number
Two common cases:
- A cover or title page that shouldn’t be “page 1.” Set the starting number to 1 but position numbering to skip the cover — or start the count from 2 if the cover is included in the page range but shouldn’t be counted.
- A document that continues from an earlier file — say, chapter 2 of a report where chapter 1 ended on page 47. Set the starting number to 48 so the numbering reads continuously across both files once combined.
Combine first, then number
If you’re assembling a document from multiple PDFs — a cover letter plus a report, or several chapters — merge them into one file first, then add page numbers. Numbering after merging gives you one continuous sequence across the whole document instead of each source file restarting at page 1. If you need to reorder pages first, Organize PDF handles that.
Notes
Numbering happens entirely in your browser — the document never leaves your device, which matters for anything not yet ready to share. There’s no watermark, no signup, and no limit on how many pages get numbered.
