How to Add Watermarks to Your PDF Documents

Sharing documents publicly or with external clients comes with the risk that your work might be copied, distributed without permission, or passed off as someone else's. Adding a watermark to your PDFs is a simple but highly effective way to assert ownership and protect your intellectual property.

What is a Watermark?

A watermark is a faded image or text displayed in the background of a document. It's visible enough to be noticed but transparent enough that it doesn't interfere with the readability of the main content.

Why Use Watermarks?

• Security: Marking a document as 'CONFIDENTIAL' or 'DRAFT' ensures the recipient understands its status.
• Branding: Adding your company logo reinforces your brand identity on every page.
• Copyright Protection: Asserting your copyright deters unauthorized use of your creative work.

Best Practices

When applying a watermark, make sure you choose an appropriate opacity (usually around 30-50%) so it doesn't obscure the text. A diagonal text watermark across the center of the page is often the most effective for security purposes.
