Frequently asked questions
Adjust the opacity down and the size to taste — a common setup is a large, light-gray diagonal watermark that's visible but doesn't obscure the text underneath.
The tool applies the watermark across the whole document by default, keeping it consistent and simple; use Extract PDF Pages first if you need to isolate a subset.
It's stamped into the page content itself like any other text, so removing it would require editing the PDF directly — it isn't a separate, easily-stripped layer.
Because the stamping happens locally, you can watermark a confidential draft without it ever passing through a third-party server first.
