  3. Adjust percentage: Slide from 0% (invisible) to 100% (solid)
  4. Preview: See real-time effect on your PDF
  5. Recommended: 30-50% for text, 20-40% for logos
Pro tip: Lower opacity makes watermark less intrusive while still protecting content!

Watermark permanence depends on application method:

Permanent Watermarks (Recommended):
  • Burned into PDF: Becomes part of page content
  • Cannot be removed: Without advanced PDF editing software
  • Flattened layers: Merged with underlying content
  • Best protection: For copyright and confidentiality
Removable Watermarks:
  • Overlay mode: Sits on top as separate layer
  • Can be deleted: By users with PDF editors
  • Use case: Temporary markings, internal drafts

Our default setting creates permanent, non-removable watermarks for maximum protection.

Absolutely secure!

  • Client-side processing: Files never uploaded to any server
  • Browser-based: All watermarking happens locally on your device
  • No data transmission: Confidential content stays private
  • Automatic cleanup: Temporary files deleted when browser closes
  • No backups: We don't store or retain any documents
Privacy guarantee: Your sensitive legal, medical, or business documents remain completely confidential!
