How it works & useful details

How to use this tool

Choose pages to number, the starting number, and a position. Selected pages receive consecutive numbers in their original document order, even if your selection is entered out of order. The prefix supports basic Latin text such as “Page ”. Numbers are drawn over existing content and do not replace old numbering; inspect the margins before sharing.

Limits and document support

Use an unencrypted PDF with 1–500 pages and a size below 50 MiB. Interactive forms are not supported; export a flattened copy first. Saving rewrites the PDF and invalidates digital signatures. Unusual document features may not survive rewriting; inspect the downloaded result.

About this tool

Add PDF page numbers stamps consecutive numbers onto all or selected pages. You control the starting number, an optional prefix such as "Page ", the font size, and one of six placement positions.

Numbers are drawn over the existing page content in document order, even when your selection is written out of order. The tool is meant for quick pagination of reports and drafts; because it does not detect existing numbering, check the margins before sharing a document that is already numbered.

How to use it

  1. Choose one unencrypted PDF file.
  2. Select the pages to number, or leave the selection blank for every page.
  3. Set the starting number, optional prefix, font size, and position.
  4. Select Add page numbers and download the result.

Worked example

A 12-page report has a cover and a table of contents that should stay unnumbered. Select pages 3-12, start at 1, use the prefix "Page ", and choose bottom centre. Page 3 then shows "Page 1" and page 12 shows "Page 10", so the numbering in the body matches the contents list.

Placement tips

  • Bottom centre is the most common choice for reports and theses. Bottom right suits documents that are read on screen.
  • Check the margins first. Numbers are drawn on top of existing content, so a footer or full-bleed image in that spot will overlap.
  • Use 9–11 pt for ordinary documents. Larger sizes suit slides exported to PDF.
  • For legal exhibits or bundles, a prefix such as "Exhibit A – " makes pages easy to reference.

Existing page numbers are not removed, so a document that is already numbered will show both. Adding numbers rewrites the file, which invalidates any digital signature. Number the document before it is signed.

Frequently asked questions

Can I avoid numbering the cover page?

Yes. Enter the pages you want to number, for example 2-10, and set the starting number to match your intended sequence.

Does it replace existing page numbers?

No. New numbers are drawn over the page, so any numbers already printed in the artwork or footer remain visible underneath.

What limits apply?

One unencrypted PDF with 1-500 pages and a size below 50 MiB. Saving rewrites the file and invalidates digital signatures; inspect the downloaded result.

Can I use Roman numerals for the front matter?

Not yet. Numbers are Arabic numerals. Number the body pages here and leave the front matter unnumbered.
