Watermark a PDF

Put DRAFT, CONFIDENTIAL or your own words across a document, or a picture of your logo, and see exactly where it lands before you download it. One stamp in the middle or a tiled pattern, at any angle, over the page or printed behind its own content. Add several files at once and they all come back marked the same way.

File history

What it does

Watermark a PDF, at a glance.

  • Stamp words or a picture, tiled or one in the middle
  • Set the colour, angle, size and how faint it prints
  • Mark several files at once, or only the first page

This tool runs entirely inside your browser tab. The file never leaves your machine, and using it needs no sign-up; downloading needs a free account. The only mark on what you download is the one you put there.

Step by step

How to watermark a PDF

  1. Drop one or more PDFs onto the page, or choose them from your machine.
  2. Type the words, or add a picture, and set the angle, colour and size. The preview shows the file itself, not a mock-up.
  3. Download the watermarked PDFs — one file, or all of them together in a zip.

Questions

Watermark a PDF: questions and answers

Yes. Add as many as you like and the same mark goes on all of them; past one file the download is a zip. Every file is stamped here in the browser, so a batch of thirty costs nothing but your own machine.
