Starting number matters more than position

The overwhelmingly common failure in numbered PDFs is an off-by-N error introduced by a cover page. If you number a 40-page report starting at 1, the cover becomes page 1 and the introduction — which the table of contents calls page 1 — becomes page 2. Every cross-reference in the document is then wrong by one.

The fix is to set the starting number to a value that makes the content pages match the contents listing, accepting that the cover carries a number too, or to number the file after removing front matter and merge it back. The starting-number field here exists for exactly this. Set it to 0 and the cover is page zero, the introduction is page one, and your table of contents is suddenly correct.

The "n of total" format compounds the same problem: the total counts physical pages, not logical ones. A 40-sheet PDF starting at 0 will read "39 of 39" on the last page. That is arithmetically consistent and almost always what you want.

Frequently asked questions

How do I stop the cover page from being numbered as page 1?
Set the starting number to 0. The cover becomes page 0 and the first content page becomes page 1, matching how your table of contents almost certainly counts.
Can I skip numbering the first few pages entirely?
Not directly. Extract the pages you want numbered, number them, and merge the front matter back on. Two tools, one minute, and no compromise on the numbering scheme.
Where on the page is the number placed?
At the bottom, in the left, centre or right position you choose, 28 points up from the page edge — inside the standard printable margin for both A4 and US Letter.
Will the number overlap my existing footer?
It might, if your footer sits in the same corner. Choose a different horizontal position, or check the last page before distributing.
What does the "n of total" format count?
Physical pages in the file, offset by your starting number. If you start at 0 on a 40-page file, the last page reads 39 of 39.
