About the PDF Watermark

Mark a PDF as a draft, a sample or confidential before sending it. Choose the words, size, angle and opacity, place the mark once in the middle or tile it across the page, and apply it to every page or only some. The watermark is added as real text, so it stays sharp at any zoom.

How to use it

  1. 1Drop in the PDF.
  2. 2Type the watermark and adjust size, angle, layout, opacity and colour.
  3. 3Choose the pages, add the watermark, and download.

Questions

Can someone remove the watermark?

A determined person with a PDF editor can. A watermark discourages casual copying and makes the status of a document obvious; it is not a security measure.

Can I use Bangla or other scripts?

Not yet. The watermark uses the standard fonts built into every PDF reader, which cover Latin letters, numbers and common symbols. The tool tells you if your text cannot be drawn.

Is my PDF uploaded?

No. The PDF is opened and changed in this browser tab using pdf.js and pdf-lib, open-source libraries that run on your device. It never reaches KuponGuru's servers, and closing the tab discards it.
