About this tool
This free PDF page numbering tool adds page numbers to every page of your document — entirely in your browser, with no upload. Choose from six positions, three number formats, a custom starting number, font size, and margin, then download the numbered PDF in seconds. Because the process runs on your device, your documents stay completely private.
How to use
- Drop a PDF file onto the uploader or click to browse.
- Select a format: plain number, Page N, or N / Total.
- Choose a position (bottom-center is the standard).
- Set the starting number, font size, and margin if needed.
- Click Add Page Numbers and download the result.
When to use a custom start number
Many documents have a cover page and table of contents that should not appear in the numbered sequence. Set the start number to 0 on those pages — they receive an invisible number and the body pages begin naturally. For a document where body pages start on page 3, set the start number to -1 so the first body page shows 1.
Frequently asked questions
How do I add page numbers to a PDF?
Drop your PDF onto the tool, choose a format (number only, 'Page N', or 'N / Total'), pick a position and any other options, then click Add Page Numbers to download the result.
Is this page numbering tool free?
Yes — completely free with no sign-up, no upload, and no limits. Everything runs in your browser.
Where are the page numbers placed?
You can place page numbers in six positions: bottom-center, bottom-right, bottom-left, top-center, top-right, or top-left. Bottom-center is the most common convention.
Can I choose the starting page number?
Yes. Use the 'Start at page' field to begin numbering at any number. For example, set it to 3 if the first two pages are a cover and table of contents that should not be counted.
Are my PDF files uploaded to a server?
No. Page numbers are added entirely in your browser using pdf-lib. Your file never leaves your device.
What formats are available?
Three formats: a plain number (1, 2, 3…), 'Page N' (Page 1, Page 2…), and 'N / Total' which shows the current page and the total count (1 / 12, 2 / 12…).
Does it work on mobile?
Yes. The tool is fully responsive and runs locally, so you can number PDFs on a phone or tablet without installing anything.
