Add page numbers

A client-side tool that adds page numbers to your PDF. Choose position, margins and starting number — everything runs in your browser (no server).

Choose File
Click or press Enter to choose a PDF. The original file input is hidden; this is a custom UI.
Choose where page numbers appear on each page.
Narrow places numbers near the edge; wide gives them more breathing room.
Set the first page number (useful if your PDF is part of a larger document).
Processing…
This tool edits PDFs in the browser using a client-side library. For large PDFs, processing time depends on your device.
