How to add page numbers to a PDF on iPhone, iPad, and Mac

A PDF can show “12 of 47” in a viewer while the printed page itself carries no number. That viewer counter is navigation chrome, not content: it may disappear when the file is printed, presented, split, or opened somewhere else.

If a report, evidence bundle, reading packet, or submission needs a visible reference on every page, add the number to the PDF itself. Preserve the original first, decide where the sequence should begin, and inspect the final stamp against the actual page content before delivery.

Number the editable source when you still have it

The cleanest time to add page numbers is before exporting to PDF. Apple documents headers, footers, and page numbers in Pages on iPhone, iPad, and Mac. If the original Pages document still exists, add the numbering there so it remains part of the editable layout, then export a fresh PDF.

That route is less useful when the source is unavailable, when several PDFs have already been combined, or when the required sequence differs from the document’s original pagination. In those cases, work on a duplicate of the existing PDF and use a dedicated numbering tool.

Do not type separate text boxes onto dozens of pages. Manual placement makes skipped, repeated, and misaligned numbers much more likely.

Plan the sequence before applying it

Write down four decisions before opening the tool:

1. Range: every page, or only a selected run?
2. Starting number: should the first stamped page be 1, 7, 101, or another value?
3. Display: ordinary numbers, Roman numerals, letters, “N of M,” or an identifier such as CASE-000001?
4. Position: which corner or centered edge stays clear of text, crop marks, signatures, and existing footers?

Front matter often uses lowercase Roman numerals while the main text begins at 1. A cover may need no visible number at all. A legal production may require a fixed-width prefix and a continuous sequence. The correct settings come from the document’s delivery rules, not from whichever preset opens first.

Add page numbers in PDF Max

Open PDF Max, choose Tools → Page Numbers, and select the PDF. The document opens behind an Add Page Numbers dialog so you can inspect the page being changed.

Then configure the run:

1. Choose All pages or enter a From and To range.
2. Set Start At to the first visible value.
3. Choose Arabic numbers, uppercase or lowercase Roman numerals, uppercase or lowercase letters, Bates Numbering, or Custom.
4. Turn on Show Page Count when the output should read as “N of M.” For a selected range, M describes that stamped range rather than the entire PDF.
5. Choose one of six positions: top or bottom, aligned left, center, or right.
6. Adjust the applicable margins, font, style, size, and color while reviewing the live preview.
7. Move through representative pages in the preview, then choose Apply only when the number clears the existing content.

PDF Max writes the labels as real PDF text in the page content rather than rendering each whole page as an image. Applying them still rewrites the document and cannot be undone in the editor, so keep the untouched source. The confirmation is intentionally separate from the preview.

Page Numbers is a Premium capability. It is not part of the Free or Pro floor, including the one-time PDF Max Pro app. PDF Max 27.1 supports iPhone with iOS 18 or later, iPad with iPadOS 18 or later, and Apple-silicon Mac with macOS 15 or later. It does not require Apple Intelligence or any downloaded language, speech, or OCR model. Check the current plan comparison before beginning a production run.

If the pages themselves are out of sequence, repair that first with the PDF page-rearrangement workflow. Numbering a scrambled document only gives every mistake a cleaner label.

Use Bates numbering for page-level identifiers

Bates numbering is a sequential identifier commonly used to reference pages in legal and records workflows. Adobe’s current Acrobat documentation describes the usual parts: a starting number, a fixed digit count, and optional prefix and suffix.

In PDF Max, select Bates Numbering, then set:

• the prefix, such as CASE-;
• the number of digits, commonly six for an output such as CASE-000001;
• the starting number, especially when continuing an earlier run; and
• an optional suffix.

PDF Max applies one configured sequence to the current PDF. It does not claim a multi-file Bates production manager. If several files must carry one continuous legal sequence while remaining separate, use a workflow that explicitly manages the complete production set. If a single combined bundle is acceptable, arrange and merge the PDFs first, then number that verified combined copy.

Record the final prefix, suffix, digit count, starting number, ending number, filename, and date outside the PDF. That run log is what lets another person continue the sequence without guessing.

Avoid covering existing content

The preview is not decorative. Check at least one page from every layout in the file:

• portrait and landscape pages;
• pages with different crop or media sizes;
• title pages and section dividers;
• pages with footnotes, signatures, stamps, or existing headers;
• dark pages that need a contrasting number color; and
• scanned pages whose image reaches the paper edge.

Move the number or change its margin rather than placing it over evidence or body text. Adding white space by resizing pages is a separate Premium operation and can affect links, outlines, or annotations, so do not introduce it merely to hide a poor numbering position.

Verify the numbered PDF

Close and reopen the saved result before relying on it:

1. Check the first and final stamped page against the planned starting and ending values.
2. Confirm every page in the chosen range has exactly one number and every excluded page has none.
3. Inspect transitions such as 9 → 10, 99 → 100, Z → AA, or the first value wider than the chosen Bates padding.
4. Print or export a harmless sample page to confirm the number is page content, not viewer chrome.
5. Search for a distinctive stamped value and copy it as text.
6. Open the PDF in a second viewer and test links, bookmarks, forms, annotations, signatures, and page rotation.
7. Compare the final file with the untouched original before delivery.

For a presentation, visible numbering helps an audience return to a cited page after the session. The guide to presenting a PDF without rebuilding slides covers the separate full-screen and presenter-control workflow.

Start with a five-page sample copy. Stamp pages 2–5 beginning at 7, preview two different page layouts, apply the run, and verify that the output reads 7 through 10 only where intended. Once that test passes, repeat the same documented settings on the real PDF.
