Automatically number every page of your PDF with customizable position, font size, and starting number. Fully browser-based — zero uploads, zero cost.
Page numbers are essential for any professional document — reports, academic papers, legal filings, books, proposals, and manuals all rely on page numbers for navigation and reference. When you share a multi-page PDF without page numbers, readers struggle to refer to specific sections, and editors can't give precise feedback.
Compressfy's free page number tool adds numerals to every page of your PDF directly in your browser. You choose the position (bottom center, bottom right, top right, etc.), the format (simple numbers, "Page X", or "X of Y"), and the starting number. Everything runs client-side using PDF-Lib — your document never touches any server.
