How to add a watermark to a PDF

PDFDistrict stamps your text across every page of the PDF, directly in your browser. Adjust the font size, opacity and rotation angle before applying it — the default settings produce a light, diagonal mark that stays out of the way of your content. Everything else on the page stays exactly as it was.

Private by design: PDFDistrict runs entirely in your web browser. No files are uploaded to any server. No account is required. Your documents stay on your device.

Watermark — frequently asked questions

Does the watermark appear on every page? +
Yes, the same watermark is applied to every page of the document.
Can I make the watermark subtle instead of bold? +
Yes. Lower the opacity to make it light and unobtrusive, or raise it for a bolder, more visible mark.
Will the watermark cover important content? +
The watermark is centered and semi-transparent by default so the original content stays readable underneath.
