About PDF page number tool

Professional documents — contracts, reports, manuals, and academic submissions — nearly always need page numbers. If you have a PDF that was created or assembled without them, DocumentFlipper makes it easy to add clean page numbers in any position without altering the existing content.

You can place numbers in the header or footer, aligned left, centre, or right. You can also set the starting number, which is useful when the PDF is one chapter of a larger document and numbering should begin at a specific page. Numbers are rendered in a clean, legible font that is consistent across all pages.

The tool adds numbers as a PDF overlay, preserving all original content including hyperlinks, form fields, and annotations. Files are processed securely and deleted within two hours.

Frequently asked questions

Can I skip numbering on the first page?
Yes — set the starting number to 0 and the first page will not show a number, with page 2 showing "1". Useful for cover pages.
What font and size are used?
We use a clean Helvetica font at 10pt, which matches professional document standards without obscuring content.
Can I customize the number style?
Currently we add plain Arabic numerals. Custom styles (Roman numerals, prefixes like 'Page X of Y') are coming in a Pro feature.
Can I add page numbers to just some pages?
Currently page numbers are added to all pages. Per-page control is on the Pro roadmap.
Is it free?
Yes — adding page numbers to your PDF is completely free with no sign-up required.
