How to Add a Watermark to a PDF (Text or Image)
Brand, mark as DRAFT or claim ownership of a PDF with a watermark — text or image, position, opacity and rotation explained.
Watermarks are tiny but powerful. They tell your reader at a glance whether a document is a draft, who owns it, or whether it's authorised for distribution.
Use cases
- DRAFT stamps on documents under review.
- CONFIDENTIAL markings on internal reports.
- Brand logos on portfolios and proposals.
- Copyright notices on photos and design files.
How to add a watermark
- Open Add Watermark.
- Upload your PDF.
- Choose text or upload an image.
- Adjust position, rotation and opacity.
- Download the watermarked file.
Design tips
- Opacity 20–35% is readable without overpowering the content.
- 45° rotation for diagonal stamps; 0° for footer-style notices.
- Place under content for branding; over content for DRAFT/CONFIDENTIAL.
