When you share a document, you want to make sure it's used appropriately. Whether you're protecting your intellectual property, branding a corporate document, or marking a file's status, a watermark is a simple yet powerful tool. It overlays text or an image onto your document, clearly communicating its origin or purpose without obscuring the content. This guide will show you how to easily add a custom watermark to any PDF for free.

Why Add a Watermark to Your PDF?

Watermarks serve several important functions in document management:

  • Assert Ownership and Copyright: For photographers, designers, and writers, a watermark with your name or logo clearly indicates that you are the creator, discouraging unauthorized use of your work.
  • Branding and Professionalism: Adding your company logo as a watermark to proposals, reports, and presentations reinforces your brand identity and adds a layer of professionalism.
  • Indicate Document Status: Use text watermarks like "DRAFT," "CONFIDENTIAL," "SAMPLE," or "COPY" to prevent misunderstandings and ensure the document is handled correctly by recipients.
  • Discourage Piracy: While not a foolproof security measure, a visible watermark makes it more difficult for your content to be passed off as someone else's.
A watermark is a digital signature that protects, brands, and clarifies the purpose of your documents with a single glance.
