An online PDF page numbering tool adds sequential page numbers to the header or footer of every page in a PDF document. You control the position (left, centre, or right), font, size, starting number, and which page to begin numbering from — the result is a professionally paginated PDF that is easy to reference and navigate.
Page numbers are essential for any document intended for review, citation, or printing: legal briefs, academic papers, business reports, and instruction manuals all require clear page references. EditPDF AI adds page numbers as a new non-destructive text layer on top of existing content, running entirely in your browser.
