What this tool does and who it is for
Add Page Numbers to PDF prints a number on each page of a document and gives you the new file. Pick the position, one of three formats, a font size and the page where numbering should start. It handles long reports, exhibits and appendices that arrived without numbers.
Formats are 'Page 1 of N', 'Page 1', or just the number. Positions are bottom center, bottom right or top right, in 10-point Helvetica by default. The numbers are drawn as small gray text on top of the existing content.
Numbers match the file's physical order, and the starting page setting lets you skip a cover by beginning at page 2.
Official Formula / Technical Standard
Real-World Worked Scenario
Select your PDF documents, apply the desired operation, and save the updated file directly to your local storage.
When people use it
Number an exhibit binder
Add 'Page X of Y' to a combined set of exhibits so everyone can cite a page in a meeting or filing.
Skip the cover page
Start on page 2 so the title page stays clean and the first content page shows as page 2 in the corner.
Long reports and manuals
Add numbers to a PDF assembled from several sources so readers can find a section by number.
Notes for US users
- Many US courts and agencies expect page numbers on filings, often at the bottom center. Check the specific local rules or the portal's instructions.
- 'Page X of Y' helps recipients notice a missing page, which matters for loan packages and contracts.
- On pages with footer text or a stamp already near the bottom edge, numbers can overlap. Look at several pages after processing.
Limits and what to double-check
- •Numbers are placed in a fixed spot with fixed gray color. You cannot enter an exact offset or color.
- •The total in 'Page X of Y' is the total page count of the whole file, even when you start numbering later. Starting at page 3 of a 10-page file shows 'Page 3 of 10' on page 3, not a renumbered sequence.
- •No roman numerals, prefixes like A-1, or different formats per section.

Frequently Asked Questions
How does the Add Page Numbers to PDF work?▼
The Add Page Numbers to PDF runs 100% inside your web browser using modern client-side JavaScript. It performs calculations, conversions, and document processing locally on your device without sending any data to external servers.
Is this add page numbers to pdf completely free to use?▼
Yes. This tool is completely free with no usage limits, no subscriptions, and no registration required.
Is my data private when using the Add Page Numbers to PDF?▼
Yes. Because all operations execute locally on your computer or phone, your inputs, documents, and data never leave your browser.
What does the start page option do?▼
Numbering begins on the page you choose and continues to the end. Earlier pages get no number. Each number equals the page's real position in the file, so a start page of 3 puts '3' on the third page, not '1'.
Can I number only some pages?▼
You can skip the beginning by choosing a start page, but there is no end page or range option. All pages from the start page to the last are numbered. To exclude trailing pages, split them off first.
Will the numbers overlap my existing footer?▼
They might. The tool does not detect existing content. Bottom center sits about a half inch up from the edge and top right is near the upper corner. If something collides, try another position or a smaller font size.
Does it change the rest of the page?▼
No. It adds a small piece of text on top and keeps everything else as is. Text remains selectable and images are unchanged. The numbers become part of the page content and cannot be toggled off later.
