How to Add a Watermark to PDF — Text and Image Watermarks

Why Add Watermarks to PDFs

Watermarks serve multiple purposes:

  • Copyright protection — Mark documents as your property
  • Confidentiality — Label documents as "CONFIDENTIAL" or "DRAFT"
  • Branding — Add your company name or logo
  • Prevent unauthorized use — Discourage copying and redistribution

Types of PDF Watermarks

Text Watermarks

Add text like "CONFIDENTIAL", "DRAFT", "SAMPLE", or your company name. Customize:

  • Font size (20-100px)
  • Color (gray, red, blue, or custom)
  • Opacity (10-90%)
  • Rotation angle (-90 to +90 degrees)
  • Position (center, corners, custom)

Image Watermarks

Overlay a logo or image on each page. Useful for branding documents with your company logo.

Best Practices

  1. Use 30-50% opacity — Visible enough to serve its purpose but does not obstruct reading
  2. Center placement with rotation — The classic diagonal watermark is hard to crop out
  3. Gray color for formal documents — Less distracting than red or blue
  4. Consistent positioning — Apply to all pages for uniform protection

Step-by-Step

  1. Upload your PDF
  2. Type your watermark text
  3. Adjust font size, color, and opacity
  4. Set the position and rotation angle
  5. Preview the result on the first page
