Frequently asked questions
Can I use an image watermark?
Not yet. Text watermarks are supported today.
Can the watermark be removed?
It is drawn into the page content, so it is not a simple toggle — but a watermark is not a security control.
Does it change the text layer?
No, existing text remains selectable underneath.
Good to know
Watermarks communicate intent — that a document is a draft, a sample or an internal copy. They deter casual misuse but should never replace real access controls on sensitive files.
