Stamp custom text — company name, date, page numbers, notices — on every page. All on your device.
PDFZero stamps custom headers and footers — company names, dates, page numbers, "CONFIDENTIAL" notices, filenames — across every page of a PDF, with left/center/right placement just like a word processor. It runs entirely in your browser with pdf-lib, so contracts and reports stay on your device.
This complements Page Numbers (which focuses on numbering styles) by handling free-form text in all six positions. For a repeated diagonal mark across the page body, use Watermark PDF.
Choose the PDF, type your text in the header row (left, center or right), and click Add. The text is stamped identically on every page and the result downloads immediately.
Yes — type {page} and {total} for numbering (e.g. "Page {page} of {total}") and {date} for today’s date. They’re replaced per page automatically.
No. The stamping runs locally with pdf-lib in your browser — the file never crosses the network.
Headers sit in the top 36pt margin and footers in the bottom 36pt. On unusually tight layouts the text may overlap content — check the first download and adjust font size if needed.
