Do I need Adobe Acrobat to add page numbers to a PDF?

No. Adding page numbers is one of the most well-supported operations across free PDF tools. The official ISO 32000-1 PDF specification defines page-level content streams and the trivial overlay operators (placing text at a specific x/y coordinate on each page) needed to draw a page number; any tool that implements those operators can add page numbers. ScoutMyTool's Add Page Numbers tool uses the open-source pdf-lib library and runs entirely in your browser — no Acrobat subscription, no upload of the file to a server.

Can I skip the cover page or title page when numbering?

Yes. Most tools, including ScoutMyTool, let you set a "start page" (the first page to receive a number) and a "start number" (the number that page should display). To skip a cover page and start the count from the second page, set start page to 2 and start number to 1. For academic papers that want roman numerals on front matter and arabic on body, run the numbering twice — once with roman on pages 1–10, once with arabic on pages 11 onward.

How do I add a custom header or footer like a document title or date?

Any text string you want repeated on every page can be added as an overlay. With ScoutMyTool, use the Add Watermark tool for a centred or diagonal header/footer string, or the Add Page Numbers tool when the text accompanies the page number itself (e.g., "Acme Contract — Page X of Y"). For multi-line headers and footers, run two passes — one for the title line, one for the page number line.

What is Bates numbering, and is it different from regular page numbers?

Bates numbering is the document-management convention used in US litigation. Every page of every document in a discovery production gets a unique alphanumeric identifier — typically a prefix (such as PROD, ABC, or SMITH001) followed by a zero-padded number (000001, 000002, etc.). Unlike regular page numbers, Bates numbers are not per-document; they continue across the entire production, so document 1 might be PROD000001–PROD000045 and document 2 starts at PROD000046. The Federal Rules of Civil Procedure (Rule 34) and most local court rules require Bates numbering on produced documents because it provides an unambiguous citation system in depositions, motions, and trial exhibits.

Will adding page numbers change the rest of the PDF?

It should not. A well-implemented tool draws the page number as an overlay in the page content stream, leaving the original content untouched. The exception is if your existing footer area already has text — your new page number might overlap it visually. The fix is to either (a) pick a different position (top instead of bottom), (b) increase the margin offset, or (c) flatten the existing footer first using a tool like Remove Annotations before re-numbering.

Can I add different page numbers to different sections (chapters / front matter)?

Yes, but you usually do it in two or more passes. For a typical book with roman-numeral front matter (pages i–x) and arabic-numeral body (pages 1–250), first run the numbering on pages 1–10 with roman numerals starting at i, then run it again on pages 11–end with arabic numerals starting at 1. The two passes do not interfere because each overlay only writes to the page range you specify.

Are page numbers required for court filings or academic submissions?

For court filings, yes — almost every US federal and state court requires page numbers on filed documents, usually bottom-centre or bottom-right, and many also require a header with the case caption. Local rules vary; check the specific court's "rules of practice" or "civil practice manual". For academic submissions, the APA Publication Manual (7th edition) requires a page number on every page in the top-right corner, the MLA Handbook (9th edition) requires the author surname plus page number in the top-right corner, and the Chicago Manual of Style allows bottom-centre or top-right depending on the document style.

Add page numbers, headers and footers to a PDF for free in 2026

By ScoutMyTool Editorial Team · Last updated: 2026-05-19

I had a 47-page client deliverable due last quarter, exported as PDF, with no page numbers anywhere. The client asked me to "add page numbers in the footer, with the project name on the left". My first instinct was to reopen the source in Word and re-export — but the source was a Figma document with embedded text frames, and the re-export would have taken half a day. The actual fix took ninety seconds in a browser: drop the PDF into ScoutMyTool's Add Page Numbers tool, pick "Page X of Y" in the bottom-right corner, paste the project name into the left footer, save. This article is the long version of what I learned that afternoon: the styles, positions, and edge cases that matter for page numbers, headers and footers in a PDF.

How "add page numbers" actually works on a PDF

A PDF is not a single editable canvas like a Word document — it is a set of fixed page content streams encoded per the ISO 32000-1 specification.¹ Adding a page number does not modify the original page content; it overlays new text at a specific x/y coordinate on top of the existing stream. That is why "add page numbers" tools never need to know anything about the rest of the document — they just paint text on top of each page at the position you pick.

The same overlay mechanism handles headers, footers, watermarks, Bates numbers, and confidentiality stamps. The differences between them are mostly which corner the text lands in, what the text says, and whether it changes from page to page (page numbers and Bates numbers do; static headers do not).

Numbering styles, and when to use each

Style	Example	When to use
Arabic numerals	1, 2, 3, 4	Default for body content of almost every document type.
Roman numerals (lowercase)	i, ii, iii, iv	Front matter — title page, preface, table of contents — in books and dissertations.
Roman numerals (uppercase)	I, II, III, IV	Less common; sometimes used for sections of legal briefs and court exhibits.
"Page X of Y"	Page 1 of 12	Multi-page contracts, statements, invoices, and any document where the recipient should know whether they have all the pages.
Bates numbering	PROD000001, PROD000002	Litigation and e-discovery — a unique sequence (often with a prefix and 6-digit padding) for every page across every document in the production.
Chapter-based	1-1, 1-2, 2-1, 2-2	Technical manuals where chapters are independently revised and re-numbered.

The "Page X of Y" style is worth a specific call-out because it solves a real problem: when a multi-page document arrives as an email attachment, the recipient cannot easily tell whether all pages came through. A footer reading "Page 7 of 12" answers that question on every page. Many contracts and statements use it by default.

Position conventions

Position	Typical use
Top right	Default for letterhead-style business documents and most office word-processor output.
Top center	Academic papers (APA, MLA — APA 7 places running head + page number top right; MLA places page number top right after surname).
Bottom center	Books, dissertations, and any document where the body text dominates and the page number should sit unobtrusively below.
Bottom right	Legal documents, contracts, and multi-page agreements; pairs well with "Page X of Y" framing.
Bottom left	Documents with a different footer convention on left (e.g., file-path stamp) and the page number on right.
Outside (mirrored)	Print-bound books — the page number sits on the outer edge of each spread (right edge on right pages, left edge on left pages).

The Chicago Manual of Style (17th edition, §1.6 and §1.7) summarises the print tradition: the page number sits at the bottom for most book content, moves to the top-right for documents whose footer carries other information (date, file-path, chapter title), and is omitted from the title page itself regardless of convention.²

Adding page numbers in five steps

Open the tool. Go to scoutmytool.com/pdf/add-page-numbers. The page loads as static HTML; no signup, no Adobe ID. The tool runs entirely in your browser tab — your PDF is never uploaded.
Drop in the PDF. Either drag the file onto the drop zone or click "Choose file" and pick it from your machine. The tool reads the PDF using the open-source pdf-lib library, which implements the ISO 32000-1 PDF specification.
Pick the style and position. Arabic, roman, or "Page X of Y" for style; bottom-centre or bottom-right are the safest defaults for position. Set the start page (the first page to be numbered — usually 2 if you have a cover page) and the start number (usually 1 or i).
(Optional) Add a left or right footer string. A project name, a date, a case caption, or a confidentiality note can sit on the opposite side from the page number. For multi-line footers, run the tool twice — once for the static line, once for the page-number line.
Download the result. The numbered PDF lands in your Downloads folder. The original content is unchanged; the overlay adds the page numbers on top of each page.

Adding a header or footer (not just a page number)

A "header" or "footer" in PDF is any text overlay that repeats on every page. The mechanism is identical to the page-number overlay — the only difference is that the text does not change from page to page. Three common cases:

Document title repeated in the header. Use ScoutMyTool's Add Watermark tool in "horizontal text" mode, position top-centre, low opacity for a subtle look or full opacity for a stronger statement.
Confidentiality stamp at the top. Same tool, "Confidential" centred at the top in a light grey or red. Some industries require this on every page of contracts and proposals.
"Draft — do not distribute" diagonal. Watermark tool, 45° diagonal rotation, low opacity, light colour. Easy to remove when the document is finalised (run the tool again with a blank string to overwrite, or re-export from source).

Bates numbering for legal e-discovery

Bates numbering — invented by the Bates Manufacturing Company in 1891 as a stamp machine for sequentially numbering documents — is the standard system for marking documents produced in US discovery. Every page in a discovery production gets a unique alphanumeric identifier, typically a prefix (PROD, ABC, SMITH) followed by a zero-padded number (six digits is common, e.g., PROD000001 through PROD123456). Unlike regular page numbers, Bates numbers persist across the entire production: document 1 might run PROD000001–PROD000045, document 2 starts at PROD000046, and so on through hundreds of thousands of pages.

The Federal Rules of Civil Procedure (Rule 34) and most state court local rules require Bates numbering on produced documents because it provides an unambiguous citation system in depositions, motions, and trial exhibits. Counsel for both sides can refer to "PROD012345" and both know exactly which page in the production they mean. To add Bates numbers in ScoutMyTool, use the Add Page Numbers tool with a custom prefix and a starting number; for productions across many documents, the cleanest workflow is to Merge PDF the entire production into a single PDF, run Bates numbering once across the merge, then Split PDF back into the original documents.

Academic submission styles — APA, MLA, Chicago

The three major academic style manuals each have specific page-number requirements:

APA 7th edition — page number in the top-right corner of every page, starting from the title page. No author name in the header for student papers (changed from APA 6). Use the "top right, arabic numerals, start from page 1" preset.
MLA 9th edition — surname plus page number in the top-right corner ("Smith 1", "Smith 2"). Run the Add Page Numbers tool with a custom prefix "Smith " (note the trailing space) and the arabic style.
Chicago Manual of Style 17th edition — bottom-centre or top-right depending on the document style. Front matter (preface, table of contents) uses lowercase roman numerals; body text uses arabic numerals starting at 1. Run the tool twice — once with roman on the front matter, once with arabic on the body.

Add Page Numbers — the primary tool this article walks through.
Add Watermark — for repeated header/footer text and diagonal "Draft" stamps.
Merge PDF — combine documents before applying a continuous Bates sequence.
Split PDF — break a Bates-numbered production back into individual documents.
Rotate PDF — fix orientation before numbering so the overlay lands in the right corner.
