What a watermark can and cannot do
A watermark is text drawn over the page content to label or discourage casual copying. It is a visible marker, not a security feature: anyone with PDF editing software can remove it. If you need to prevent opening or editing, use Protect PDF, and combine it with a watermark when you want both.
Choosing the settings
A visibility of 20 to 35 percent at a 45 degree angle is a classic look that stays legible. Use the repeated layout for pages with lots of white space or images, and a single centred mark for clean text pages. The text must use Western letters, numbers and common symbols, because the built-in fonts cannot draw other scripts or emoji.
Example use cases
Drafts
Mark documents that are not final so nobody mistakes them for finished copies.
Confidential files
Label sensitive documents before you share them.
Review copies
Stamp the recipient's name or For review only on a shared copy.
