Page numbers
Add page numbers to any PDF, even one that was assembled from several source files. Pick a corner or edge position, set a starting number, and customize the format — plain "1, 2, 3" or something like "1 / 24" — with a live preview of page one. Numbering is applied with pdf-lib entirely in your browser.

Frequently asked questions
How does the format template work?
Use {n} for the current page number and {total} for the total page count — for example "{n} / {total}" produces "1 / 24", "2 / 24", and so on.
Can I start numbering from something other than 1?
Yes. Set the starting number field to whatever page number the first page should show.
Is my file uploaded to a server?
No. Numbering and the live preview both run entirely in your browser.
