Add page numbers to a PDF online, free
A PDF without page numbers is a navigation problem — readers cannot quickly jump to a referenced section, and printouts become impossible to reassemble if dropped. Whether you are finalizing a report, a legal brief, a thesis, or a user manual, adding page numbers is a finishing step that makes every multi-page document more professional. This free online tool stamps sequential numbers onto every page of your PDF in seconds, with full control over position and format.
You choose exactly where the numbers go. Top or bottom of the page, and left, center, or right within that zone — six position combinations covering virtually every document style. The starting number lets you offset the sequence: if you're adding page numbers to a chapter that starts at page 15 in a larger document, enter 15 and the numbering picks up from there. This is also useful for excluding front matter like title pages and tables of contents that typically use a different numbering scheme.
The numbers are stamped in the margin zone so they do not overlap existing page content when default positioning is used. Adjust the margin value if your document has very tight content that extends into the usual margin area. The output PDF is fully compatible with all PDF readers and printing systems — no fonts embedded, no special viewer required, just clean standard-compliant page numbers on every page.
PDF page numbering, explained properly
How page numbers are placed without disturbing your content
Numbers are drawn into a defined margin band — top or bottom, by your chosen alignment — that sits outside the document's existing content area by default, so the number never overlaps text or images from the original PDF. This is a straightforward stamp operation: unlike merging or splitting, no page objects are rebuilt, just a small text element added to each page's content stream at render time.
Why the "start number" setting exists
Documents rarely want their cover page labeled "1" — that's what the start-page and start-number controls solve together: begin numbering visually from page 2 while still displaying "1" on it, so the cover stays unlabeled and the first content page reads correctly. The same mechanism handles multi-part documents, like a chapter that should continue from page 47 of a larger work rather than restart at 1.
Plain numbers vs. "Page X of Y" and other formats
This tool stamps a simple running integer — the format overwhelmingly used in contracts, reports, and everyday documents. If you need the fuller "Page 3 of 24" convention (common in legal and academic documents so a reader can confirm no pages are missing) or Roman numerals for front matter, the Headers & Footers tool supports {page} and {total} tokens for that composed format, and the Full PDF Editor offers per-section control for documents with mixed numbering schemes.
Why add page numbers to a PDF
Top or bottom position
Stamp numbers in the page header area (top) or footer area (bottom) — your choice.
Left, center, right alignment
Position numbers at the left margin, centered, or at the right margin to match your document style.
Custom starting number
Set any starting number — useful for chapters in a larger book or documents that skip a title page.
Applied to every page
Numbers are added to the entire document regardless of page count — no page selection needed.
Non-overlapping placement
Numbers are placed in the margin area so they do not overlap existing page content at default settings.

Your files stay private
Your privacy comes first. Browser-only tools run entirely on your device — your file never leaves your browser. Advanced tools that need heavier processing use secure server-side processing: the file is sent over an encrypted connection, handled in memory, and automatically deleted right after your download. Either way, we never store, share, or analyze your documents — and it stays free, needs no account, and adds no watermark.
