How to add page numbers to a PDF with OnyxPDF
- Drop your PDF into the tool.
- Pick the format: plain, “Page 1”, “Page 1 of 12”, “1 / 12” or “– 1 –”.
- Pick the position and the starting number.
- Click “Add Page Numbers” and download the numbered PDF.
Why do it in your browser instead of uploading?
- Free with full format and position control — Smallpdf reserves page numbering for Pro.
- Start from any number, so a chapter can begin at page 47 without fake front pages.
- No upload: number a manuscript or report locally.
- Numbers are real text stamped into the PDF, visible in every reader and in print.
Good to know (honest limits)
- Numbers are stamped onto the pages; they do not renumber automatically if you later delete pages — re-run the tool after reorganising.
- One style per pass; run the tool again on the output if you need a second numbering scheme.
Frequently asked questions
Can I start numbering from a number other than 1?
Yes. Set any start value — useful when the PDF is one chapter of a larger document.
Can I skip the cover page?
Number the whole document starting at 1, or split off the cover first with Split PDF, number the rest starting from 1, then merge them back in order.
Where can numbers be placed?
In a 3×3 grid of positions: top or bottom (or middle rows), left, centre or right.
Is my file uploaded?
No. The numbers are stamped in your browser and the file downloads directly.
