Watermark PDF

Stamp text over every page.

Add a watermark to a PDF to mark it confidential or draft

Sending out a draft contract, an internal report, or a proposal before it is final often calls for a visible label on every page, something a reader cannot miss or crop out. Watermark PDF stamps your own text diagonally over each page so status is clear at a glance.

The text defaults to the word confidential, but you can type anything: a company name, a draft date, or a do not distribute notice. You pick the font from a short list, set the size, choose a color, and decide whether it should be bold or italic. Opacity starts around thirty percent so the mark sits behind readable text instead of blocking it, and rotation defaults to a forty five degree diagonal, though any angle works.

Smaller files are watermarked in your browser, while larger or complex PDFs go over a secure connection to the servers and are removed within the hour.

How to use the Watermark PDF tool

  1. Add your PDF file: drag & drop or click to browse.
  2. Set your options: Watermark text, Opacity (0-1), Font, Font size.
  3. Click “Process Watermark PDF” and download your result.
