PDF Page Number Adder — Add Page Numbers to PDF

How to Add Page Numbers to PDF Documents

Then click "Add Page Numbers" and download your numbered PDF instantly — no email, no sign-up.

Why Use UtilityX PDF Page Number Adder?

Unlike cloud-based tools, UtilityX processes everything directly in your browser using pdf-lib. Your documents are never transmitted to any server, making it the safest way to add page numbers to sensitive PDFs — contracts, tax documents, medical records, legal papers, or anything private.

What Happens to the Original Files?

Nothing — your original PDF file is not modified. The tool creates a new PDF with page numbers added and offers it as a download. Your source file remains untouched on your device.
