Professional reports, legal discovery bundles, academic dissertations, and corporate contracts require accurate, consistent page numbering to ensure seamless referencing and compliance with formal submission standards. PDFPK’s Add Page Numbers tool lets you stamp custom page numbers across your PDF with complete control over formatting, starting offsets, font sizing, and header/footer positioning.

Place numbers at top-left, top-center, top-right, bottom-left, bottom-center, or bottom-right.
Start numbering at page 1, page 5, or any custom starting value to accommodate preface pages.
Numbers are rendered using crisp standard Helvetica vector fonts that match executive standards.
Pagination executes locally in browser memory. Documents are never uploaded to remote cloud servers.
Paginate hundreds of pages in under 2 seconds without waiting in server queues.
In PDF specifications, coordinates are measured in points (1/72 of an inch) calculated from the bottom-left origin (0,0) of the MediaBox. Placing page numbers accurately across documents with mixed orientations requires dynamically calculating the active page width and height, subtracting margin offsets, and measuring text bounding widths so numbers remain centered or right-aligned without clipping outside the printable boundary. PDFPK dynamically calculates these metrics for every single page in your document.
In litigation and discovery proceedings, attorneys and paralegals must identify every page uniquely. Adding consistent page numbers (e.g. "Page 14 of 120") establishes evidentiary chain-of-custody and prevents disputes over whether pages were altered or omitted during depositions and trial.
