Page numbers are sequential labels added to each page of a PDF document, typically in the header or footer area. They help readers navigate long documents, reference specific content, and maintain order when pages are printed and collated.
Professional documents — reports, proposals, theses, manuals — require page numbers for navigation and citation. If you've created a PDF from scanned pages, images, or merged documents, it likely lacks page numbers. Adding them improves readability and gives your document a polished, professional appearance.
Upload your PDF and choose where to place page numbers: top or bottom of the page, aligned left, center, or right. Convertful uses pdf-lib to draw the page number text onto each page. The original content is preserved — numbers are added as a new layer. Everything runs in your browser.
