Drafts, proofs, ownership and controlled sharing
Watermarked PDF
A watermark identifies a document; it does not replace encryption.
Controlled sharing
Use a watermark to communicate status or ownership
A good watermark is visible enough to communicate context without making the document difficult to read. Use it for drafts, proofs, internal copies or ownership—not as a substitute for actual access control.
- Draft and review copies
- Client proofs
- Ownership or internal-use marking
- Opacity and contrast
- Readable text and important page content
- Whether sensitive information also needs encryption or redaction
Keep the watermark short. “DRAFT”, “CONFIDENTIAL” or a light brand mark usually communicates more effectively than a paragraph across every page.

A human tip
A watermark should communicate, not hide the document
A useful watermark is noticeable enough to communicate status or ownership but restrained enough that the document remains readable. For proofs and internal copies, subtle placement and opacity usually work better than a giant diagonal stamp.
