How to Add Page Numbers to a PDF

Page numbers turn a loose stack of pages into a document people can navigate, cite, and discuss — “see page 14” only works if there's a 14 to see. Merged PDFs, scanned reports, and exported slide decks often arrive with no numbers at all. Here's how to add them cleanly in your browser.

Why add page numbers

• Navigation & citation — reviewers and readers can reference exact pages in feedback, emails, and legal filings.
• Print order — numbered pages are easy to re-sort if a printout gets shuffled.
• Professional finish — reports, contracts, and proposals look unfinished without them.
• After merging — combining several PDFs almost always breaks any original numbering; adding fresh sequential numbers fixes it.

Step-by-step: add page numbers with ToolsGravity

1. Open the PDF Page Numbers tool and upload your PDF.
2. Pick where numbers appear — footer or header, left, centre, or right.
3. Choose a starting number and format (e.g. 1, Page 1, or 1 of 20).
4. Apply and download the numbered PDF.

Tips

• Skip the cover page. Start numbering from the second page so the title page stays clean — set the start page accordingly.
• Keep clear of the margin edge. Numbers too close to the edge can be cut off when printed; a small inset is safer.
• Number after merging, not before. If you're combining files with the PDF Merger, merge first, then number the finished document so the sequence is continuous.
• Reorder first if needed. Fix the page order with the PDF Page Organizer before numbering, so the numbers match the final layout.

Summary

Adding page numbers takes seconds and instantly makes a PDF easier to navigate, cite, and print. Merge and reorder first, choose bottom-centre or bottom-right, use a 1 of 20 format when completeness matters, and start after the cover page. The ToolsGravity PDF Page Numbers tool does it all in your browser — nothing to install.
