Why Add Watermarks?
Watermarks serve multiple purposes: marking drafts, indicating confidentiality, establishing ownership, warning recipients not to share, or showing document status. A watermark makes document purpose immediately clear while remaining visible without obstructing content.
Common Use Cases
Typical uses include marking drafts, stamping confidential documents, adding "COPY" marks, indicating version status, showing approval status, protecting intellectual property, or marking time-sensitive documents.
