A watermark signals status (“DRAFT”, “CONFIDENTIAL”), ownership (a logo), or discourages casual reuse. Done right it’s readable but doesn’t fight the content.
Text vs image watermark
- Text — quick for DRAFT/CONFIDENTIAL/COPY; control font, size, rotation, opacity.
- Image — a logo or signature stamp; control size and opacity.
How to add a watermark step by step
- Open Watermark PDF and select your file.
- Pick Text or Image mode and enter the text or upload the logo.
- Set opacity (~20–35% is the sweet spot), rotation (−45° is classic for “DRAFT”), and position.
- Apply to all pages or a range, preview, and download.
Tips
- Keep opacity low so the document stays readable — a watermark is a hint, not a redaction.
- Diagonal, centered text resists simple cropping better than a corner stamp.
- A watermark is not security. To actually restrict a file, also password-protect it; to remove content, redact it.
