How to Add Page Numbers to a PDF — Free

Updated for 2026

Page numbers make printed reports, assignments and legal files far easier to navigate. Add them to every page in a couple of clicks — free, in your browser, no software to install.

Quick answer: Open the page-number tool, pick a position (center, left or right) and a starting number, add your PDF, and click. The numbers are written onto each page.

Real-world use — what we verified

We added bottom-center numbers to a 30-page manual and they sat neatly under the text.

Honest note: numbers are drawn as text using a standard font, so they won't match a custom brand typeface — but they're selectable and print cleanly.

When numbering helps

Printed reports & theses — readers can reassemble dropped pages.
Legal & contracts — page references actually mean something.
Multi-file bundles — after merging several PDFs, a single running number keeps order.

Step-by-step

Open the page-number tool (browser-based, no signup).
Add your PDF.
Pick a position — bottom-center is the default; left/right also available.
Set the start number (1 by default; use 2 if page 1 is a cover you add later).
Click “Add page numbers” and download.

Common pitfalls

Already-numbered pages — the tool draws a fresh number; if a page already has one, you'll get two. Remove the old numbers first or accept the overlap.
Cover pages — numbering starts at the first page; add an unnumbered cover after, or start at 2.
Orientation — numbers are placed by page coordinates, so they follow each page's own rotation.

FAQ

Will it renumber automatically?

Yes — it numbers pages sequentially from your start value (1, 2, 3…) across the whole file.

Can I skip the first page?

The current tool numbers every page. To leave a cover unnumbered, add the cover page after numbering, or start at 2 and keep page 1 as the cover.

Does numbering change my text or images?

No — numbers are added as a separate text layer on top; your existing content is untouched.
