PDF Page Numbering

How to use PDF Page Numbering

1. Choose your PDF.
2. Pick the position and the starting number.
3. Check the preview, particularly the first and last pages, then download.
4. Numbers are drawn onto the page content and cannot be removed afterwards — keep the original.
5. For double-sided printing, the outer corner alternates sides; avoid the inner margin.
6. Processing runs in your browser and the file is never uploaded.

Position, and why the outer corner

Bottom centre is the safe default and works for anything. For a document that will be printed double-sided and bound, the convention is the outer corner — which alternates between left and right as the reader turns pages, so the number is always visible at the edge without opening the book flat. Avoid the inner margin entirely: on a bound document that is where the numbers disappear into the gutter.

Starting numbers and front matter

Formal documents conventionally number front matter — title page, contents, foreword — in lowercase Roman numerals and start Arabic numbering at the first page of the body. If your PDF already contains front matter, set the starting number so the body’s page 1 lands where a reader would expect, which usually means starting the count several pages in. Court filings, theses and formal reports often have rules about this that are worth checking before you commit.

Numbering is drawn on, not structural

The number is added as page content at fixed coordinates. It does not change the PDF’s internal page labels, so a reader’s page navigation box may still show a different number from the one printed on the page — which is exactly the mismatch that makes a numbered PDF confusing to navigate. Where it matters, some tools can set the document’s page labels as well; visually adding numbers is the common case and usually sufficient.
