Number every page of a PDF in the position and style you choose. On Firefox it runs in the browser, so there is nothing to install.

2.Pick where the numbers go.
3.Download the numbered PDF.

Tips for Firefox

• Works with strict tracking protection on.

What happens to the rest of the page

• Numbers are added on top of each page; the original content is not rewritten.
• Every page is numbered in one step.

Questions people ask

+Does numbering change my pages?
