Watermarks are a professional way to protect your documents, mark drafts, or brand your work. Whether you want to stamp "Confidential," "Draft," or your company name across every page of a PDF — here is how to do it for free in seconds.

What is a PDF Watermark?

A watermark is a semi-transparent text or image that appears over or behind the content of each page in a PDF. Common watermark uses include:

  • "CONFIDENTIAL" or "PRIVATE" — to mark sensitive documents.
  • "DRAFT" — to mark works in progress before final approval.
  • Company name or logo — to brand all outgoing documents.
  • "SAMPLE" — to send preview versions of products without enabling unauthorized use.
  • Copyright notice — to assert ownership of original work.

How to Add a Watermark to PDF — Step by Step

  1. Upload your PDF to our free Watermark tool.
  2. Enter your watermark text (e.g., "CONFIDENTIAL" or your company name).
  3. Choose position and opacity if available.
  4. Click Add Watermark.
  5. Download your watermarked PDF.

The watermark is added diagonally across the center of each page, matching the professional style used in legal and corporate documents.

Is a Watermark Permanent?

When added through a PDF tool, the watermark is embedded directly into the PDF content. It cannot be easily removed by the recipient without specialized software. While very determined users with Adobe Acrobat and editor access could potentially remove it, a watermark is an effective deterrent and legal proof of your ownership.

Can I Add an Image Watermark?

Our current tool supports text watermarks. For image watermarks (like a logo), you would need a more advanced design tool like Adobe Acrobat or Canva. For most purposes — especially marking drafts and confidential files — text watermarks are just as effective.
