About the Add Page Numbers to PDF

Add Page Numbers stamps every page with a configurable label. The format can combine the current number and final number through {n} and {total} tokens, with a chosen starting value and font size.

Six positions cover left, centre, and right at the top or bottom of the page. A first-page preview reflects the label, position, and scale before the PDF is created.

Numbers are added as PDF text without rasterizing source pages. They use a standard Helvetica font and fixed grey colour, and existing page labels or printed numbering are not removed.

Frequently asked questions

Can numbering start at zero or another value?
Yes. The Start number field accepts zero or a positive starting value.
What does {total} display?
It displays the final number in the sequence, calculated from the start value and page count.
Can only selected pages be numbered?
No. This tool numbers every page; Header and Footer PDF supports page ranges.
Can I change the font or colour?
The current tool uses embedded Helvetica in a fixed dark grey; size and position are adjustable.
Does numbering alter existing text?
It adds a new text label and does not remove existing content, so inspect possible overlaps.
