Why Add Page Numbers Privately in Your Browser?

Whether you are submitting an academic dissertation, filing legal trial exhibits, or presenting a proposal to executive leadership, clear pagination provides essential structure and makes referencing specific findings effortless.

Rather than sending your contracts and confidential manuscripts to external cloud servers, FileConvert computes vector coordinates and stamps page numbers directly in client browser memory using pdf-lib. The document is updated instantly with zero server uploads, keeping your private intellectual property safe.

Flexible Placement & Format Options

Position numbers anywhere along headers or footers, customize starting counts, omit cover sheets automatically, and select from standard formats like Page 1 of 25 or simple numerals.

Frequently Asked Questions

Are my files uploaded to a remote server to add page numbers?

No. The pagination process executes 100% client-side in your web browser using pdf-lib. Your confidential documents are never uploaded to any remote server or cloud service.

Can I skip numbering the title or cover page?

Yes. Enable the 'Skip First Page / Cover' option. The first page will remain clean and unnumbered while subsequent pages start numbering automatically.

What numbering formats are available?

You can choose from popular standards including 'Page X of Y', 'X / Y', simple numbers 'X', or styled dashes like '— X —'.

Will adding page numbers obscure existing page text?

Page numbers are inserted with standard document margins (approximately 25–35 points from the edges). You can position numbers in either header or footer zones to avoid colliding with text.
