Frequently asked questions
Can the watermark be removed again?
The watermark is added to the page content. It is not a security feature: someone with a PDF editor can remove it. For real protection use a password.
Can I watermark only some pages?
Yes. Enter pages such as 1-3 or 2,5 in the pages field; "all" marks every page.
Is the text still readable under the watermark?
Yes, with the default opacity of 25 % the watermark stays in the background. Increase it for a stronger mark.
