Add Page Numbers to PDF

Why Add Page Numbers to a PDF?

A PDF without page numbers is fine for short documents, but for anything longer than a few pages — a report, a contract, a manual, a thesis — page numbers are essential. They help readers navigate the document, make it easy to reference specific sections in discussions, and look more professional overall. If you have ever received a 40-page PDF with no page numbers and had to say "look at the page about halfway through," you know exactly why this matters.

Common Situations Where You Need This

• Academic Papers and Theses: Universities and journals almost always require page numbers on submissions.
• Business Reports: Reports shared with clients or management need page numbers for easy reference in meetings.
• Legal Documents: Contracts and court documents require numbered pages for accurate reference.
• Manuals and Guides: A user manual or training guide without page numbers is difficult to use.
• Books and E-books: Any multi-chapter document benefits from numbered pages.

How to Add Page Numbers

1. Click the upload area and select your PDF — a preview of the first page appears.
2. Choose a position for the page number: Top Left, Top Right, Bottom Left, or Bottom Right. A red dot shows where the number will appear.
3. Click "Add Page Numbers" — the tool processes every page.
4. Click "Download PDF" to save your numbered document.

Quick Notes

Q: What size is the page number text?
A: The numbers are added at size 16pt, which is clearly readable without being distracting.

Q: Does it start numbering from 1?
A: Yes. The first page of your PDF gets number 1 and each page counts up from there.

Q: Is my PDF sent to a server?
A: No. PDF.js and jsPDF run entirely in your browser. Your file is never uploaded anywhere.
