About Add Page Numbers to PDF

Stamp page numbers onto every page of a PDF right in your browser — no software to install and nothing sent to a server. Choose from six positions: top or bottom, and left, center, or right. Pick a format that suits your document: plain numbers (1, 2, 3), labelled numbers (Page 1, Page 2), fractions (1 / 10, 2 / 10), or full labels (Page 1 of 10). Set a custom starting number if your document is part of a series — for example, start at 5 if the first four pages belong to a different section. Three font sizes let you match the numbering to the proportions of your document. The page numbers are added as text in a neutral grey, positioned 20 points from the edge for a clean look. All processing happens locally in your browser. The original file is never modified — the tool produces a new PDF ready to download immediately.
