A watermark is text or an image overlaid on each page of a document. It's one of the simplest ways to protect intellectual property, mark documents as confidential, or indicate draft status.
Why Use Watermarks?
- Copyright protection: Prevent unauthorised use of your work
- Document classification: Mark as "Confidential," "Draft," or "Internal Only"
- Ownership assertion: Prove a document's origin
- Deterring theft: Make it impractical to claim your work
- Version tracking: Mark drafts or superseded documents
Types of Watermarks
- Text watermarks: A word like "CONFIDENTIAL" placed diagonally across pages — most common and easiest to apply
- Image watermarks: A logo or seal placed on the document — common for branding
How to Add a Watermark on FileZone
- Open the Add Watermark tool

- Click Process
- Download your watermarked PDF
Best Practices
- Opacity: Use 20–40% for a professional look — 100% will obscure content
- Diagonal placement: Harder to crop out than corner watermarks
- Keep it brief: One or two words work best
- Consistency: Use the same style for all client deliverables
💡 Pro tip: Combine a watermark with PDF password protection for maximum security. The watermark deters casual copying while encryption prevents unauthorised access.
