Number PDF Pages Clearly
Add page numbers to a PDF when a report, packet, application, or printable document needs clearer references, navigation, or page order cues.
The tool adds visible page numbers to all pages or only the selected pages in the PDF and returns one updated PDF file.
How to use Add Page Numbers to PDF
Upload one PDF file.
Leave Pages to number blank for all pages, or enter a range such as 1,3-5,8.
Choose the number position, format, start number, and font size.
Click Add Page Numbers to create the numbered PDF.
Download the updated PDF file.
Why this helps in real workflows
A report should show page numbers before review or printing.
A longer packet needs easier page references for comments or approvals.
A PDF export lost its page numbers and should be repaginated.
A printable handout should show clear page counts and positions.
Common problems and fixes
The PDF has no visible page numbers for review or printing.
Add page numbers to the full document or only the pages that need pagination.
A page range should start at a custom number instead of 1.
Set the start number you want before creating the updated PDF.

Frequently asked questions
How do I add page numbers to a PDF online?
Upload one PDF, choose the page range, numbering position, and numbering style, click Add Page Numbers, and download the updated file.
Can I number only part of a PDF?
Yes. Leave the range blank to number the full PDF, or enter specific pages or ranges such as 1,3-5,8.
What numbering styles are available?
This version supports plain numbers (1, 2, 3), Page 1 format, and 1 / 12 format that shows the total page count alongside the current page number.
Can I place page numbers at the top of the page?
Yes. Choose from six positions: top-left, top-center, top-right, bottom-left, bottom-center, and bottom-right.
Can I start numbering at a number other than 1?
Yes. Change the Start number field to begin the page numbering sequence at another value.
Can I adjust the font size of the page numbers?
Yes. Set the font size before generating the numbered PDF. Use a larger size for print-heavy layouts or documents with dense page content.
Do the PDF files leave my browser?
This tool is designed to run in the browser with pdf-lib, so page numbering happens locally in a modern browser session.
