Add Page Numbers to PDF — Position, Format, Size

How to add page numbers to a PDF in your browser

1. Choose the PDF.
2. Pick where the numbers sit (bottom center is the classic; bottom right is the print-shop default), how they read (a bare number, "Page 3", or "3 of 12"), and how large.
3. Hit Add Numbers & Download. Every page in the document gets its number in the same place, in a neutral gray that reads on white pages without shouting.

Why "N of M" and not just numbers?

"3 of 12" tells the reader something a bare number cannot: how much is left, and whether the file is complete. For reports, manuals and anything that gets read out of order (shared single pages, forwarded screenshots of a PDF), the total is the difference between "I lost my place" and "I know exactly where I am". The tool writes the real total, counted from the actual document — no typing it in by hand.

Will the numbers collide with my content?

The margin control exists for exactly that: documents with full-bleed footers or dense bottom margins want "Far" or a top position. Because the numbering is a local render of your own file, you can try a position, check the downloaded result, and re-run with a different setting — each attempt costs nothing and touches nothing on any server.

Does it work on scans and image PDFs?

Yes. Page numbers are drawn on top of whatever the page contains, so a 40-page scanned contract gets the same clean treatment as a typeset report. The numbers are real, selectable text (not an image), so search and copy work on them.

Can it number only some pages?

This tool numbers every page, which is the job it does well. If your document needs a cover without a number or Roman numerals up front, the honest workflow is: number the body, then remove the first page's number by editing — or compose the document in two parts and merge. We'd rather tell you the limit than pretend the one-click covers every typesetting case.

FAQ

• Is my file uploaded to a server? No. The tool runs entirely in your browser — your file never leaves your device. You can verify it yourself: open the network panel and there is no upload request while you work.
• Do I need an account, and is it free? No account and no cost. It is free to use — no signup, no paywall, no daily limit.
• Which browsers does it work in? Any modern browser — Chrome, Edge, Firefox and Safari — on desktop or mobile.
• Is there a size limit? There is no server-side limit because nothing is uploaded. Practical limits come from your device's memory, which comfortably covers normal documents and photos.
• Does it work with encrypted PDFs? Standard PDFs work in every tool. If a file is password-protected, Unlock PDF opens it for you when you have the password, and Protect PDF applies a new 256-bit AES password. No tool bypasses encryption without the key.
