How to add page numbers to a PDF (free)
Stamp page numbers onto every page — choose the corner, the format, the starting number, and the size. All in your browser, with nothing uploaded.
1. Open the PDF
Open your file in the editor, or start from the Add page numbers page, which opens the dialog as soon as you pick a file.
2. Open the Page numbers dialog
Choose Pages → Page numbers… (or the Page numbers button in the sidebar).
3. Pick a format
Use a one-click preset or write your own format string:
{n} / {total}— "3 / 12" (the default),Page {n}— "Page 3",ABC-{n:6}— zero-padded Bates numbering ("ABC-000003"), as used for legal document production.
{n} is the page number, {total} the page count, and
{n:6} pads the number to six digits — any surrounding text is stamped
literally, so prefixes like a case or invoice code just work.
4. Position, start number, size
Choose one of six positions — bottom left / centre / right or top left / centre / right — set the number to start at (useful when a cover page shouldn't count from 1), and pick a font size (11 pt by default).
5. Apply and save
Click Apply — the numbers are stamped on every page. Not right? Undo, tweak, re-apply. Then click Save to download the numbered PDF.
