How to Add Page Numbers to a PDF: Position, Start Number and Cover Pages

Where page numbers should go

Our tool offers three positions: bottom center, bottom right and top right. Each fits a different kind of document, and we pick based on what readers and recipients expect rather than personal taste.

If a court, university or tender authority publishes formatting rules, those rules win. Check them before you number, because changing your mind afterwards means renumbering from the unnumbered original.

• Bottom center: the classic choice for reports, theses, manuals and anything that will be printed and bound.
• Bottom right: suits business documents, board papers and bundles that people flip through, because the number sits where the thumb lands.
• Top right: common for legal filings, manuscripts and some academic formats, and it stays visible when pages are stapled at the bottom.

Using the start number

The start number lets the first page of your PDF carry any number, not just 1. That is more useful than it sounds. If your file is the second volume of a bundle and the first volume ends on page 48, start at 49 and the numbering of the whole package runs on without a gap. If a thesis chapter is submitted separately but must match the page numbers in the full thesis, set the start number to the chapter's real first page.

One thing to keep in mind: the start number changes what is printed, not the page positions inside the PDF. Your PDF viewer will still call the first page page 1. When someone asks you to remove page 12, check whether they mean the twelfth page in the file or the page with 12 printed on it.

What about the cover page?

Many style guides want a cover page without a number, with the next page as page 2, or sometimes as page 1. Our tool numbers every page in the file; it has no switch to skip the first page. We prefer to say that plainly rather than leave you hunting for an option that is not there.

The workaround is reliable and takes a minute. Remove the cover from the PDF, number the remaining pages with the start number you want (2 if the cover counts, 1 if it does not), and then use Merge PDF to put the cover back in front. The same method works for a table of contents or front matter that should stay unnumbered, as long as the unnumbered pages sit at the start.

How to add page numbers with pdfdots, step by step

Add Page Numbers runs in your browser, so nothing is uploaded. You need a free account; the free plan covers 3 tasks a day for files up to 10 MB, and the Bronze, Silver and Gold plans raise those limits for bigger bundles.

• 1. If your document is made of several files, merge them first with Merge PDF so the numbering runs straight through.
• 2. Open Add Page Numbers and drop the PDF into the box.
• 3. Choose the position: bottom center, bottom right or top right.
• 4. Set the start number, for example 1, or 49 if this file continues an earlier volume.
• 5. Click Add page numbers, download the result and check the first, a middle and the last page.

Legal bundles, theses and board papers

For legal bundles, the biggest mistake we see is numbering each exhibit separately and merging afterwards. Every exhibit then starts at 1 and references like "see page 7" become ambiguous. Merge first, put the pages in the right order with Organize PDF, and number once at the end. If the court wants exhibit separators, insert them before numbering so they get a number too, unless the rules say otherwise.

For theses, check whether your faculty wants roman numerals for front matter. Our tool prints ordinary numerals only, so if roman numerals are required, add those in your word processor and use our tool for the main body or for appendices that arrive as separate PDFs. For board papers, bottom right with a clean merge of agenda, minutes and reports gives directors something they can actually navigate during a meeting.

Common numbering mistakes and how we avoid them

Numbering twice is the classic one. If a source file already had numbers in its footer and you add ours in the same corner, the two overlap and look sloppy. Before numbering, we scroll through the PDF and check whether any pages already carry a number. If they do, we pick a different position, or we number only the part that lacks numbers and merge the rest afterwards.

The second mistake is numbering too early. Every later change, such as inserting a missing annex, deleting a duplicate page or moving a chapter, shifts the order, and the printed numbers no longer match. We treat page numbers as one of the final steps: assemble, reorder, remove what does not belong, then number. If the file also needs a DRAFT or CONFIDENTIAL mark, Add Watermark can run before or after numbering, since the watermark sits in the center and the numbers sit at the edge.

Finally, keep the unnumbered version. If a reviewer asks for one more document to be inserted in the middle, you rebuild from the clean file instead of trying to work around numbers that are already printed on the pages.
