Add Page Numbers

About the Add Page Numbers

Page numbers turn a stack of loose-looking pages into a proper document — easy to reference in a meeting, easy to reassemble if printed, and simply more professional. Adding them by hand is tedious; adding them automatically takes seconds.

This Add Page Numbers tool stamps clean, consistent numbers onto your PDF in your browser, with control over where they sit. Nothing is uploaded, so you can number confidential reports and contracts privately.

How to use the Add Page Numbers

1. Add your PDF by dragging it in or clicking to browse.
2. Choose where the page numbers should appear and how they look.
3. Click to add the numbers to every page on your device.
4. Download your numbered PDF, ready to share or print.

How the Add Page Numbers works

This tool works directly with the internal structure of your PDF using established open-source engines (pdf-lib and PDF.js) that implement the ISO 32000 PDF specification. Everything runs locally in your web browser through JavaScript, which means the document is read, modified and re-saved on your own device — it is never transmitted to a server. That is what makes the process both instant and genuinely private.

Because the pages are handled at the object level rather than being re-printed, text stays selectable and sharp and images keep their original quality unless you deliberately choose to compress them.

Tips & best practices

• Place numbers in a bottom corner where they will not clash with existing headers or footers.
• Add page numbers after you have finalised the page order, so the numbering matches the final sequence.
• For legal or reference documents, numbers make it much easier to cite specific pages precisely.

Standards & accuracy

Built on the PDF (ISO 32000) standard and processed entirely in your browser, so files are never uploaded.

Because processing happens locally, results are consistent and repeatable. For scanned PDFs (images of text with no selectable text layer), text-based operations require OCR first — the tool works with the document's existing text layer.

Privacy & security

The Add Page Numbers runs entirely inside your web browser. Your data — whether that is a file, figures or text — is processed on your own device and is never uploaded to a server, stored or shared. There is no signup and no account, so you can use it as often as you like while keeping full control of your information. This makes it a safe choice even for confidential and sensitive work.
