How to Add Confidential and Draft Watermarks to PDF Pages Online
Sending pitch decks to investors, draft contracts to clients, or mock exam papers to students requires copyright protection to prevent unauthorized redistribution. iEditPDF's Watermark PDF tool lets you stamp diagonal semi-transparent text watermarks (like 'CONFIDENTIAL', 'DRAFT', or 'DO NOT COPY') or company logos across your PDF pages with exact opacity and angle controls.

Perguntas frequentes
Can someone easily delete the watermark from my PDF?
When combined with our 'Flatten PDF' feature, the watermark is merged directly into the base vector content of each page, preventing standard PDF editors from simply selecting and deleting it.
What opacity should I use so my text is still readable?
An opacity setting between 15% and 25% provides the perfect balance: the watermark is unmistakable, yet dark body text remains 100% legible.
Can I add an image logo watermark instead of text?
Yes! You can upload transparent PNG logos or stamps and scale them to appear in the center or in the corner of every page.
