Page numbers turn a loose stack of pages into a navigable document. They are essential for printed reports, legal exhibits and any file someone will reference by page in a meeting.
How to add page numbers in PDFelly
- Open the Page Numbers tool and add your PDF.
- Choose a position (footer centre is most common), font size and format.
- Set the starting number if the first pages are covers.
- Apply and download.
Format options that matter
- "Page X of Y" reassures readers nothing is missing.
- Starting offset lets you skip a cover or table of contents.
- Margins — keep numbers clear of existing footers and the printable area.
Order first, then number
Numbering reflects the current page order, so finalise the document first. If you still need to rearrange, do that with reorder or merge before adding numbers — otherwise the numbering will be wrong.
Privacy
Like every PDFelly tool, page numbering happens in your browser. A contract you are paginating for signature never leaves your device.
Formats and starting numbers
The "Page X of Y" format reassures readers that nothing is missing, which is valuable for contracts and reports. A simple running number suits informal documents. If your file opens with a cover and a contents page, set a starting offset so numbering begins on the first real page rather than the cover — otherwise your printed "Page 1" lands two sheets in.
Placement and avoiding clashes
Footer-centre is the safe default, but check that your chosen position does not collide with content already on the page, such as an existing footer, a logo or a signature block. Keep numbers inside the printable margin so they are not trimmed when the document is printed. A modest font size that matches the document's body text looks more professional than oversized numbers.
Number last, not first
Page numbers reflect the current page order, so add them only once the document is final. If you still need to merge in extra pages or reorder sections, do that first; numbering a document you then rearrange guarantees the numbers will be wrong and you will have to redo them.
Frequently asked questions
Can I start numbering from a page other than the first?
Yes. Set a starting offset so covers or contents pages are skipped and numbering begins where you want.
Can I use 'Page X of Y' format?
Yes, that format is supported and is popular for contracts and reports because it shows the total page count.
Where should page numbers go?
Footer-centre is the common choice. Keep them clear of existing footers and inside the printable margin.
Should I number before or after editing?
After. Finalise the page order first, since numbering reflects the current arrangement.
Page numbers in real documents
Where page numbers matter most is in documents people discuss or cite. In a contract, numbered pages let signatories confirm nothing was inserted or removed. In a report shared with a committee, "see page 14" only works if the pages are numbered the way readers expect. In legal exhibits, consistent numbering across a bundle is often a formal requirement. The details that trip people up are predictable: counting a cover or contents page as page one so the printed numbers are off by a sheet or two; placing numbers where they collide with an existing footer; and numbering before the document is final, then adding pages and leaving the sequence wrong. Avoiding these is mostly about order and offsets — finalise the pages, set the starting number to skip front matter, choose a position clear of existing content, and only then apply. Done last, numbering is a thirty-second job that makes a document genuinely easier to navigate.
