What this tool does
This tool stamps page numbers onto every page of a PDF. You choose the position (bottom centre, bottom right, top centre and so on), the style (plain numbers, “Page 3” or “3 / 20”), the starting number and the font size.
The numbers are drawn in a standard font on top of the existing pages; the page content itself is never modified.
How to use it
- Choose a PDF — the tool shows the page count.
- Pick a position and a number style.
- Set the starting number (usually 1) and the font size (12 suits most A4 documents).
- Press “Add page numbers” and download the result.
Supported formats
- Input: PDF files (up to 15 MB)
- Output: the same PDF with page numbers stamped
Limitations
- Numbers are drawn with Latin digits in an embedded Noto font; other scripts are not stamped.
- The tool cannot detect existing page numbers — if the document already has them, the stamps may overlap; choose a different position in that case.
- Password-protected PDFs cannot be modified.
Frequently asked questions
The number overlaps my content — what do I do?
Choose a different position (for example top centre instead of bottom right) or a smaller font size. The stamp sits near the page edge, so most margins are safe.
Can numbering start from a specific number?
Yes — set “Start numbering at” to any number, useful when appending a section to an existing report.
Will the numbers look the same in print?
Yes, they are real vector text drawn into the PDF, not an image, so they print sharply at any size.
