Add Watermark to PDF Windows

If you have ever worried about your PDF getting copied 

Have you ever shared a PDF and worried someone might copy it or pass it off as their own? That’s where a watermark comes in. A watermark is simply text, a logo, or even an image placed on your PDF pages to show who the document belongs to, or to add important details like your brand, copyright, or identity. Think of it as a personal stamp on your file. And nowadays people don’t add watermarks just to say Draft or Final and give the status of the document. They add them for ownership, personalization, and protection, like putting their brand logo, signature, or even a copyright mark. It’s more about making the PDF theirs and ensuring others recognize its source or can’t misuse it easily.

In this guide, I’ll explain what a watermark in a PDF really is, why it’s useful for personalization and security, and show you step-by-step how to add one on Windows, both using Systweak PDF Editor and Microsoft Word. (your all-in-one PDF tool).

You must have seen them in contracts, reports, or drafts to indicate status, ownership, or to prevent misuse.
