Where watermarks matter

Document Status

Differentiate draft from final automatically in your document pipeline. Apply "DRAFT" on generation, remove on approval.

Confidentiality

Every document shared externally carries a clear "CONFIDENTIAL" marker. Applied programmatically, never forgotten manually.

Brand Consistency

Apply your company logo to every output document. Watermark at generation time, not after the fact.
