How to add page numbers to a PDF, skip the cover and get “Page 1 of N” right
Page numbers are the small thing that makes a long document usable: a reader can say “page 14, second paragraph” and be understood, a printed stack can be put back in order, and a reviewer can refer to a table without describing it. Word processors add them automatically; PDFs assembled from scans, exports and merged files often have none, or have several competing sequences. This guide shows how to add clean, consistent numbers with Add Page Numbers without uploading anything, how to skip a cover without producing “Page 1 of 10” on the second sheet, and how to number a document made from several files.
Formats: Page 1 of 10, 1 / 10, or your own
Four presets cover most documents. Page 1 of 10 is the default and the most useful: it tells the reader where they are and how far there is to go, which matters on screen where the stack of paper is invisible. 1 / 10 says the same in less space. Page 1 and a plain 1 suit documents where the total is obvious or changes often. Custom takes any pattern with {n} for the current number and {total} for the last one — Sheet {n} of {total}, - {n} -, {n} of {total} pages — in Latin letters, digits and common symbols, which is what the standard PDF fonts contain.
Numbers are written as real text in Helvetica, black, at Small, Medium or Large (9, 11 or 14 points). They can be selected and searched, they print sharply, and they add a few hundred bytes to the file rather than a picture per page.
Adding the numbers
- Open Add Page Numbers and add the file, or up to 20 files that should be numbered the same way. Each row shows the page count and a preview.
- Choose a Format, or Custom and type a pattern. The panel shows what the first numbered page will read.
- Choose a Position: bottom centre is the convention for reports and books, bottom right or top right for documents read on screen, and top centre for anything whose footer already carries text.
- Set Start on page and First number if the document has a cover or continues an earlier sequence (see below); otherwise leave both at 1.
- Pick Size and Margin — Normal, about 13 mm from the edge, keeps numbers clear of most printers' unprintable border — then click Number and download.
The file never leaves your browser and the original on disk is not modified; the result is a new file named after the original with -numbered added. Bookmarks, links, annotations, editable form fields and metadata are kept, because pages are numbered in place rather than copied.
Skipping the cover: what “of N” should count
A cover page rarely carries a number, and a table of contents often does not either. Set Start on page to 2 (or 3, or wherever the body begins) and those pages are left untouched. The question is then what the total should say. There are two honest answers, and Add Page Numbers lets you pick either with First number.
- First number 1: the first numbered page reads Page 1 of 9 on a 10-page file. The total counts the pages that carry numbers, so the last page reads Page 9 of 9. This is what most reports and theses do: the cover is outside the numbered sequence.
- First number 2: the first numbered page reads Page 2 of 10 and the last reads Page 10 of 10. The number matches the physical position in the file, which is what you want when readers will quote page positions from a viewer's page counter.
The rule behind both: the total is the first number plus the count of numbered pages, minus one. To continue a sequence from an earlier volume that ended on page 48, set First number to 49 and Start on page to 1; the total then runs to the correct final number.
Numbering merged files and scans
Numbers should be added last. If a document is assembled from several PDFs, combine them first with Merge PDF, then number the merged file once so the sequence runs through the whole document without restarting; numbering the parts first gives three documents that each begin at page 1. The same order applies to Split & Organize PDF: reorder and delete pages first, number afterwards.
Scans need one more thing. A page scanned sideways is usually stored sideways with a rotation flag that tells viewers to turn it; a number placed naively would land on the visual side of the page. Add Page Numbers places numbers in the reader's view — after the rotation, inside the crop box if there is one — so the bottom centre is the bottom centre of what you see. If a scan is upright in the file but visually wrong, fix it first with Rotate PDF.
A footer that already contains text — a running title, a confidentiality line, an old page number — will collide with a new number at the bottom. Choose the top, the opposite corner or a wider margin. Existing numbers are not detected or removed; the tool adds, it does not edit.
What Add Page Numbers will not do
It refuses encrypted PDFs — remove the password with Unlock PDF first and, if the file should stay protected, put it back with Protect PDF after numbering — as well as digitally signed documents, since re-saving would invalidate the signature, and XFA forms. It does not offer free positioning, Roman numerals or per-section restarts; a document that needs front matter in i, ii, iii and a body in 1, 2, 3 can be split, numbered as two files with different patterns, and merged. And it does not remove or renumber pages: that is what Split & Organize PDF is for.
