How to add a header and footer to a PDF with OnyxPDF
- Drop your PDF into the tool.
- Type the header and/or footer text, using {page}, {total} and {date} placeholders where you want live values.
- Set size and position.
- Click “Apply Header & Footer” and download the stamped PDF.
Why do it in your browser instead of uploading?
- Live placeholders: {page} and {total} resolve per page, {date} stamps today — no manual per-page work.
- Free — header/footer tools are commonly Pro-tier elsewhere.
- Consistent branding for reports, proposals and handouts without reopening the source document.
- No upload: stamp internal documents locally.
Good to know (honest limits)
- One header/footer style per pass; the stamp is drawn onto pages, so changing your mind means re-running from the original.
- Existing content under the stamp area is covered, not moved — pick margins that are actually empty.
Frequently asked questions
What placeholders can I use?
{page} for the current page number, {total} for the page count, and {date} for today’s date. They can be mixed with your own text, like “Report — page {page} of {total}”.
Can the header differ on the first page?
Not in one pass. For a different first page, split the cover off, stamp the rest, and merge them back — all three tools are on this site.
Will it overwrite my content?
The stamp is drawn in the margin areas you choose. If your document’s margins are very small, the stamp may overlap content — check the first page of the result.
Is my file uploaded?
No. Stamping happens in your browser.
