Frequently asked questions
Is the watermark applied to every page?
Yes, the watermark is stamped consistently across all pages of the document.
Can recipients remove the watermark?
The watermark is drawn into the page content, so it can't be switched off in a viewer, though no watermark is impossible to remove with dedicated editing tools.
