Add Page Numbers to Any PDF Online
Add professional page numbers to a PDF without any desktop software. Choose where the numbers appear (any of six positions), what format to use, what number to start from, and how large to make them. The modified PDF downloads directly — your original stays untouched and the process runs entirely in your browser.
Page numbers turn a messy stack of unorganized pages into a professional document. They're essential for contracts, reports, dissertations, handouts, and any multi-page document where readers need to navigate quickly.
How It Works
Upload your PDF. Pick the position, format, start number, and font size. Click Add Page Numbers. The tool uses pdf-lib to load each page, draw the number text at the chosen position, and save the modified PDF to your device. No upload, no watermark, no signup.
Formatting Options
Pick from simple numerals (1, 2, 3), counts (1 of 10), prefixed (Page 1), or both (Page 1 of 10). Start-number is useful for documents that continue from a previous PDF, so you can pick up at page 11 or 23 or wherever you need.
Privacy
Your PDF never leaves your computer. pdf-lib runs entirely in your browser, modifying the file in memory and serving the result back to you as a download. You can verify by disconnecting from the internet before clicking the convert button — the tool still works.
FAQ
Can I skip the first page (cover)?
Set start number to 0 — page 1 will get "0", but you can also open the PDF and delete the first page's number afterward.
Does it overwrite existing page numbers?
No — it adds new numbers on top. If your PDF already has numbers printed in the same position, they'll overlap.

Why Use This PDF Page Numberer?
The PDF Page Numberer runs entirely in your browser, which means three things matter for you. First, it's instant — there's no server round-trip, no upload, no waiting on someone else's queue. Second, it's private — nothing you enter ever leaves your device, which makes it safe for sensitive numbers, draft copy, or files you don't want sitting on a third party's servers. Third, it's free forever — no signup, no email capture, no "basic vs. pro" upsell. Open the page, get the answer, close the tab.

Privacy & How Your Data Is Handled
Every calculation and every transformation in the PDF Page Numberer runs locally in your browser using standard JavaScript. We don't upload your input to any server, we don't log it, and we don't pass it to a third-party API. The tool works the same whether you're on a fast home connection or completely offline once the page has loaded. If you want to verify this for yourself, open your browser's network tab and run the tool — you won't see any outbound request carrying your data.
