The fastest way: free online page-number tool
To add page numbers to a PDF, open the Add Page Numbers tool, drop in your PDF, choose where the numbers go and what they look like, then download the numbered file. No signup, no watermark — everything runs in your browser.
Step by step
- Open the Add Page Numbers to PDF tool.
- Drop your PDF into the "Drop a PDF here" zone.
- Choose a Position — Bottom center is the default; Top or Bottom combined with left, center or right gives six placements.
- Set Start numbering at — keep 1 for a full document, or enter a higher number when numbering a later chapter.
- Pick a Number format for the style you want.
- Choose a Colour that contrasts with your pages so the numbers stay readable.
- Click Add page numbers and download your numbered PDF.
Why add page numbers?
Reports, theses, contracts and manuals are hard to navigate without them. Page numbers let readers cite exact pages, help you spot a missing page in a printout, and make scanned documents feel like finished publications.
Tips for clean page numbers
- Pick a colour that contrasts with the page — dark numbers on white pages, light numbers on dark scans.
- Avoid Bottom center if your pages already have footers; try Bottom right instead.
- Numbering a chapter? Set "Start numbering at" to the chapter's first real page number.
- Check the first pages after numbering before sharing the file.
Frequently asked questions
How do I add page numbers to a PDF for free?
Open the free Add Page Numbers tool, drop in your PDF, choose a position, start number and format, then click Add page numbers and download. No signup needed.
Can I start numbering from a number other than 1?
Yes. The ‘Start numbering at’ field accepts any number, which is handy when you are numbering a single chapter of a larger document.
Where can I place the page numbers?
Six positions are available: top or bottom of the page, each in left, center or right alignment.
Will it work on scanned PDFs?
Yes. The numbers are stamped onto the rendered pages, so scanned or image-based PDFs work just like text PDFs.
Are my files uploaded anywhere?
No. Numbering happens entirely in your browser — your PDF never leaves your device.
