Free Online PDF Page Number Tool

Add Page Numbers to PDF Online

This free online PDF page number tool lets you add page numbers to one or more PDF files in your browser. You can upload PDFs, choose the page number position, display style, font size, color, weight, font family, and starting number, then export new numbered PDF files.

Everything runs locally in the browser without uploading your PDF to a server. It works well for contracts, proposals, reports, handouts, training files, archives, and other PDFs that need consistent page numbering. If you need to add page numbers to PDF online, batch number PDF pages, or insert page numbers into selected PDF pages, this tool is built for that workflow.

What this PDF page number tool is useful for

  • add page numbers to PDF files in batch
  • number contracts, quotes, and approval documents
  • place page numbers on reports, presentations, and training materials
  • apply numbering to selected pages instead of the whole PDF
  • add page numbers to scanned or reorganized PDFs
  • standardize numbering across manuals, proposals, and internal documents

Supported page number options

  • Position: top left, top center, top right, bottom left, bottom center, bottom right
  • Style: plain number, Page 1, or 1 / 20
  • Custom template: formats such as Page {n} or Page {n} of {total}
  • Start number: begin numbering from any value
  • Font size and color: adjust the appearance of the page number
  • Weight: regular or bold
  • Font family: choose common Windows and macOS fonts, and optionally load browser-accessible local fonts
  • Batch processing: upload multiple PDF files and export each result separately
  • Page targeting: apply numbering to all pages or only a custom page range

How to add page numbers to PDF

  1. Upload one or more PDF files
  2. Choose the page number position
  3. Choose the page number display format
  4. If needed, switch to a custom template for your own page number style
  5. Set font family, font size, color, weight, and starting number
  6. Choose all pages or a custom page range
  7. Export the numbered PDF

How custom page ranges work

If you only want to add page numbers to part of a PDF, use a page range:

  • 1-3 means pages 1 through 3
  • 6 means only page 6
  • 1-3,6 means pages 1 through 3 and page 6
  • 2,4,8-10 means multiple single pages plus a continuous range

This is useful when you want to skip a cover page, leave an appendix unchanged, or number only the main body of a PDF.

How custom page number templates work

If the built-in styles are not enough, you can use a custom template.

  • {n} means the current page number
  • {total} means the total number of pages in the PDF

Common examples:

  • Page {n}
  • Page {n} of {total}
  • P-{n}
  • Section page {n}

This is helpful when you need a more formal or document-specific numbering style.

What the starting page number means

The starting number is the number shown on the first processed page. It does not have to match the physical page index inside the PDF.

For example:

  • Start number 1: the first selected page shows 1
  • Start number 5: the first selected page shows 5

This is useful when the PDF already has a cover, table of contents, front matter, or when you want numbering to continue from another document.

Font and language support

This tool also works for non-English page number styles, including Chinese text such as 第 {n} 页. You can choose from common font families or try loading local fonts that your browser can access.

Common practical choices include:

  • Microsoft YaHei
  • PingFang SC
  • SimSun / Songti
  • SimHei / Heiti
  • Arial
  • Helvetica

If you only need simple numeric page numbers, the default font is usually enough.

Common use cases

  • add page numbers to reports and manuals
  • number contracts, quotations, and receipts
  • add footer page numbers to handouts and training materials
  • re-number organized or scanned PDFs
  • standardize page numbering in proposals and bid documents
  • prepare printable PDFs with clear page order

Usage tips

  • If the PDF contains mixed page orientations, check the previewed result after export so the numbering matches your intended reading direction
  • If you only want to number the main content, use a custom page range instead of applying numbering to the whole file
  • Bottom center and bottom right are common choices for formal documents
  • For longer documents, Page {n} of {total} is usually clearer than a plain number

Why use an online PDF page number tool

This tool is designed for one job: add page numbers to PDF files quickly. You do not need desktop PDF editing software or a complicated document workflow. Upload the file, choose the numbering style, export the result, and you are done.

That makes it useful for people searching for a fast way to add page numbers to PDF online, batch number PDF pages, or insert page numbers into selected PDF pages without leaving the browser.

Privacy

PDF reading, page numbering, and export all happen locally in your browser without sending files to a server. That is a better fit for contracts, internal reports, finance files, and other PDFs that should stay on your machine while you work.
