What Is PDF Page Numbering?
Adding page numbers means stamping a running count — like "1", "Page 1", or "1 of 12" — onto every page of a PDF, in a consistent spot such as the bottom center or top right. It's the small detail that makes a long document easy to navigate, cite, and reassemble if it's ever printed and shuffled.
This tool reads the PDF you add directly in your browser, lets you choose the position, format, and starting number while previewing it on the actual first page, then stamps every selected page and hands you the finished file — all without uploading anything to a server.
Why Use Our Page Numbering Tool?
Most online numbering tools ask you to upload your document to a remote server, wait in a queue, and trust that it's deleted afterward. This tool takes a different approach: reading the PDF and stamping the page numbers both happen inside your own browser tab using JavaScript libraries. Your document never leaves your device.
- No account or sign-up: open the page and start numbering immediately.
- No file uploads: nothing is transmitted to a server for processing.
- No paid API: numbering runs on free, open client-side libraries.
- No hidden limits: number as many pages as you like, however you like.
Key Features of Our Page Numbering Tool
Live preview
See exactly how the number will look on page 1 before you commit, updating instantly as you change settings.
Six placement options
Bottom or top, left, center, or right — pick the spot that fits your document's layout.
Multiple number formats
Plain numbers, "Page 1", "Page 1 of N", "1 / N", or "- 1 -" — choose the style you need.
Custom starting number
Start counting from any number, useful when a document continues from an earlier volume.
Selective page ranges
Number every page, or only a specific range like "2-10", leaving the rest untouched.
Skip the cover page
One click excludes page 1 from numbering, so a title page stays clean.
Benefits of Using Page Numbering
- Easier navigation: readers can reference and find specific pages at a glance.
- Cleaner citations: page numbers make it simple to reference exact passages in reports and papers.
- Print-safe ordering: if a printed copy gets shuffled, numbers make it easy to put back in order.
- Stay private: in-browser processing means your document never touches a third-party server.
- No software to install: everything runs in the browser you already have open.

Why Choose Our Online PDF Tool?
There's no shortage of PDF numbering tools online, but many route your file through a server, require a paid plan, or limit how many pages you can stamp per day. This tool is built around a simpler premise: number entirely on your device using free, open libraries — no paid conversion API involved — and stay free to use without a login.
Privacy and Security
Because numbering happens client-side, the PDF is read directly into your browser's memory, the page numbers drawn there, and the result written back out as a new file — at no point is the document content sent to a server operated by this site or anyone else.
Common Use Cases
- Long reports and theses where readers need to reference specific pages.
- Legal documents and contracts that benefit from a clear, printable page count.
- Books and manuscripts being prepared for printing or self-publishing.
- Multi-volume sets that need numbering to continue from a custom starting number.
Frequently Asked Questions
Is this Page Numbering tool really free?
Yes. There's no sign-up, no per-file fee, and no watermark added beyond the page numbers you choose.
Is my file uploaded to a server?
No. Reading the PDF and stamping the page numbers both run inside your browser using JavaScript. Your document is never transmitted anywhere for processing.
Can I start numbering from something other than 1?
Yes. Enter any starting number in the "Starting number" field, and counting will begin from there.
Can I leave my cover page without a number?
Yes. Check "Don't number the first page" and the numbering will begin from the second page instead.
Can I number only part of the document?
Yes. Enter a range like "2-10" in the "Pages to number" field, and only those pages will be stamped.
Can it number a password-protected PDF?
No. Files that require a password to open are not supported — remove the password with a PDF unlock tool first, then add page numbers to the result.
Conclusion
Adding page numbers shouldn't require uploading a sensitive document to an unknown server or installing desktop software. This tool aims to make numbering fast, private, and free — previewing, placing, and stamping your pages entirely on your own device, from a short memo to a full-length manuscript.
