Frequently Asked Questions
01Can I add an image logo?
Currently we support text watermarks, but we are working on logo/image support for a future update.
02Can the watermark be removed?
Once applied and flattened into the PDF, the watermark becomes part of the page image and is difficult to remove, providing good basic protection.
