How the pdf page number adder works

For each page, the tool measures the width of the text in Helvetica 11 point and draws it 24 points above the bottom edge, centered or aligned to a margin of 36 points. Processing uses the open source pdf lib library in your browser.

Worked example

Common uses of the pdf page number adder

• Course packs.

Tips and common mistakes

Set the first number to 2 if your cover page should be unnumbered but counted.

Check that the footer area of your pages is empty to avoid overlap.

Background: what to know before you rely on it

PDF files do not reflow like word processor documents, so page numbers must be drawn on each page. Standard fonts such as Helvetica are built into every PDF viewer, which means the numbers display the same everywhere without embedding a large font. Numbering after merging files is a common workflow because the final page count is only known at the end.

Private, free and fast

This tool runs entirely in your browser. What you type or choose is not uploaded to a server and is not saved after you close the page, which keeps it fast and private. It is free to use as often as you like. See more in all pdf and media tools, or browse the full list of tools.
