A page number is a promise.

Page numbers let people point to the same place in a document. They work best when added after you know exactly which pages belong and in what order.

Finish the structure first

Merge the relevant files, remove unwanted pages, and correct the reading order before numbering. Otherwise a later deletion can make visible page numbers disagree with the document’s actual positions.

Inspect the margins for existing footers, signatures, or printed numbers. A new number placed on top of an old one creates confusion rather than clarity.

Apply and inspect

Open Page Numbers, upload the final PDF, and review the available position and appearance settings. Run the tool and download the result.

Check the first page, a middle page, and the last page. Confirm that the number does not overlap content or fall outside the printable area. Review both portrait and landscape pages if the document mixes orientations.

Explain offsets when necessary

A cover sheet or unnumbered introduction can mean PDF position 6 displays printed page 3. Visible page numbers do not automatically change a viewer’s internal page labels. If readers will use the viewer’s page box, specify which numbering system your references use.

Preserve consistency

After distributing a numbered document, avoid inserting pages into that same version without updating references. Publish a clearly named revised copy when the sequence changes.

For a review packet assembled from several documents, continuous numbering can help reviewers discuss the packet as a whole. Keep any original page references that are important to understanding the source, and make clear which numbers apply to the combined copy.
