How the Add Page Numbers to PDF works
Upload your PDF.
Choose the position: bottom centre, bottom right, bottom left, top centre, top right, or top left.
Set the starting number, font size (6–24pt), and number format: "1, 2, 3…", "Page 1, Page 2…", or "1 of 10, 2 of 10…".
Optionally enable "Skip first page" to leave a cover page unnumbered, then click Add Page Numbers and download.
Tips & tricks
- All 6 position options are on one dropdown (3 bottom + 3 top corners/center) — there's no live preview, so double-check the position after downloading if you're unsure.
- The "n of total" format calculates the total automatically from your starting number and whether you skipped the first page — you don't set the total manually.
- Font size is adjustable from 6pt to 24pt but the font itself is fixed to Helvetica — there's no font family selector.
- Processing runs entirely in your browser via pdf-lib — no upload.
Frequently Asked Questions
Can I start page numbering from a number other than 1?
Yes. Set the starting number field to any value — useful when combining documents where different sections have separate numbering.
Can I skip the first page (cover page)?
Yes. Enable the "Skip first page" option — numbering starts from the second physical page, which displays as your chosen starting number.
What number formats are available?
Three: plain numbers ("1, 2, 3…"), labeled ("Page 1, Page 2…"), or numbered-of-total ("1 of 10, 2 of 10…"). The total in the last format accounts for the starting number and any skipped first page.
What font is used for the page numbers?
Helvetica (built into the PDF specification) is used for clean, universally compatible rendering — there's no font choice.
