How to Watermark PDF Online: Protect Your Intellectual Property
In the digital age, unauthorized sharing of documents is rampant. Whether you're sending a draft manuscript, a confidential business proposal, or a design portfolio, you need a way to claim ownership.
The simplest, most effective method? Watermarking.
What is a PDF Watermark?
A watermark is a semi-transparent text or image overlay applied to your document pages. It typically says things like "CONFIDENTIAL," "DRAFT," or your company name. It doesn't block the content, but it makes it impossible for someone else to claim the work as their own.
Why You Should Always Watermark
- Copyright Protection: Clearly marks the work as yours.
- Status Indication: Lets recipients know if a document is a "DRAFT" or "FINAL."
- Branding: Ensures your logo or name is visible on every page, even if printed.

Best Practices for Watermarking
- Don't Overdo It: A watermark that is too dark makes the document hard to read.
- Diagonal is Best: Placed diagonally across the center is the hardest to remove or crop out.
