FAQ

Is my PDF uploaded anywhere?

No. Page numbers are added in your browser using pdf-lib. Your file stays private.

Can I start numbering from a page other than 1?

Yes. Set the 'Start from' field to any number — useful when the PDF is part of a larger document.

Can I add a prefix like 'Page '?

Yes. Enter any prefix text in the optional prefix field and it will appear before each number.

Where will the numbers appear?

You can place numbers at the bottom or top, and choose left, center, or right alignment.

Before you use this tool

Number pages after arranging the document

Page Numbers adds a visible sequence to make a shared or printed packet easier to reference. The new number is separate from an existing footer and does not update a table of contents, internal links, or PDF page labels.

Choose a position that avoids footnotes, signatures, and logos. Number near the end of the workflow because later insertion, deletion, or reordering can make the visible sequence inaccurate.

  • Check header or footer clearance
  • Arrange pages first
  • Verify first and last pages

Your file never leaves your device

Add Page Numbers to PDF runs entirely in your browser. When you open a file, it is read into the page on your own computer and processed there — it is not uploaded to a server, stored in the cloud, or seen by anyone else. When you are done, the result is generated locally and downloaded straight to your device.

That matters because PDFs so often hold something private: a signed contract, a tax return, an invoice with a client's details, a scan of an ID. Many online PDF services quietly upload your document to process it. Because this tool keeps the work on your machine, you can work with your PDF without handing the file to a third party.

Tips for a clean result

  • Start from the original PDF where you can. Re-exporting from Word or a scanner app usually gives a cleaner file than one that has already been through several tools.
  • Very large files take longer because all the work happens on your device. Closing other heavy browser tabs frees up memory for big documents.
  • Keep a copy of the original until you have checked the output. Because nothing is stored online, the version on your device is the only copy of the result.
  • A modern browser on desktop handles the widest range of PDFs. Most tasks also work on mobile, though precise work is easier on a larger screen.
