FAQ
Can I choose the watermark text?
Yes, type anything — a name, a date, "CONFIDENTIAL," a company name.
Does the watermark cover the actual content?
It's stamped diagonally and semi-transparently — visible, but not blocking the document from being read.
Can I combine this with an invisible fingerprint too?
Yes — turn on Guarded to add invisible per-copy tracing on top of the visible watermark.
