How to Add Page Numbers to a PDF for Free (No Upload)

You've merged a report, combined scans, or assembled a thesis — and now it needs page numbers. You don't need Acrobat or a sketchy upload site. Here's the private, free way.

The fastest method

Open the Add Page Numbers to PDF tool, drop in your file, and click the button. It adds clean centered numbers (like "3 / 12") to the bottom of every page and gives you the result to download. The whole thing runs in your browser using JavaScript — the PDF is never uploaded anywhere, which matters for contracts and statements.

Why "in your browser" matters

Most free PDF sites upload your document to their servers to process it. For anything sensitive — IDs, bank statements, legal documents — that's a real privacy risk. Browser-based tools do the work on your own machine; you can even disconnect from the internet and it still works.

Get the document right first

Number after you've assembled the final document, not before. Combine your files with Merge PDF, drop unwanted pages with Delete Pages, and fix any sideways scans with Rotate PDF — then add the numbers so they run in sequence.

Common uses

Theses and dissertations (examiners require numbering), legal bundles, multi-invoice statements for your accountant, printed handouts, and any document where someone will say "see page 7".

Keeping the file small

Adding numbers barely changes the size, but if your PDF was already large, run the result through Compress PDF before emailing or uploading it to a portal with a size limit.
