Will the watermark be on top of or behind page content?

On top with the chosen opacity. For visual deterrence, 25% opacity in the center is the standard.

Can recipients remove the watermark?

Anyone with PDF editing tools can remove drawn elements. For tamper-resistant marking, combine with Protect PDF and signatures.

How does the Image Watermark work?

Stamp a logo or any image as a watermark on every page of a PDF — useful for branding draft documents, deterring unauthorised redistribution, or marking confidential exports. Opacity-controlled (15-30% is the standard "background watermark" look) and position-tunable (center for the classic full-page watermark; corners for subtle branding). For text watermarks like "DRAFT" or "CONFIDENTIAL", use Add Watermark instead.
