Why this comes up after merging

A document assembled from several files almost never has usable numbering. Each source started at 1, so the combined file counts 1, 2, 3, 1, 2, 1, 2, 3, 4, and anyone asked to "see page 7" has no way to find it.

That is the common path here: merge the parts, then number the result once so the sequence runs continuously. Court bundles, tender responses and academic submissions usually require exactly this, and are commonly returned without it.

The conventions worth knowing

  • Covers are not numbered. Set skip-first to 1 so the title page stays clean and numbering begins on the first content page.
  • "Page 1 of 24" helps recipients. The total tells someone whether they are holding the whole document, worth using for anything that will be printed and passed around.
  • Bottom centre is the safe default. It survives double-sided printing without landing in the binding, unlike bottom-left or bottom-right on alternating pages.
  • Continue a sequence across files by setting the starting number, if part one ended at page 30, start part two at 31 and the whole submission reads as one document.

Numbers as text, not as pictures

The numbers are drawn as text objects on the existing page, so nothing underneath changes. The document stays selectable and searchable, the numbers stay sharp at any zoom, and the file barely grows.

This matters more than it sounds. A tool that flattens pages to images to stamp a number turns a crisp, searchable document into a stack of pictures, usually larger than the original and noticeably softer in print. If you also need the file under a size limit, number first and compress afterwards, so the limit applies to the finished document.

Getting the order right

  1. Assemble everything, merge the parts.
  2. Fix the pages, rotate, delete and reorder until the sequence is final.
  3. Number it, once, so the numbers match the final order.
  4. Compress last, if there is a size limit to meet.

Numbering before reordering is the mistake to avoid: the numbers stay where they were drawn, so a reordered document ends up numbered out of sequence, which looks worse than not numbering it at all.

Frequently asked questions

Can I leave the cover page unnumbered?

Yes, set "skip first" to 1 and numbering begins on page 2. That page then becomes number 1 unless you also change the starting number, which is the convention most reports and dissertations follow.

Can I start numbering at something other than 1?

Yes. Set the starting number to continue a sequence from another document, useful when a submission is assembled from several files and the numbering has to run continuously across all of them.

Will the numbers overlap my existing content?

They are placed in the page margin, which is empty on most documents. If your pages already have footers, choose a top position instead, or add a margin before numbering.

Are the numbers real text?

Yes. They are drawn as text objects, so they stay sharp at any zoom, print cleanly, and can be selected and copied like the rest of the document. Nothing is rasterised.

Why does my court or university submission need numbered pages?

Because anything referenced needs a stable address. Court bundles, tender responses and academic submissions commonly require continuous numbering so a specific page can be cited unambiguously, and rejections for missing numbers are routine.
