How to Use & Tips - Add Watermark

1How to Use Add Watermark

  1. Upload the PDF document you want to stamp with a watermark.
  2. Look at the live preview to instantly see how the watermark will appear.
  3. Use the settings panel to change the text, color, size, rotation, and opacity.
  4. Click 'Save & Download PDF' to finalize your watermarked document.

2Professional & Security Tips

  • Use a semi-transparent color (lower opacity) to ensure the original content remains readable.
  • A diagonal rotation (like 45°) is usually the hardest to remove and covers the page evenly.
  • For confidential documents, a bright red color is standard to immediately catch attention.

What is Add Watermark?

The Add Watermark tool allows you to stamp text or image overlays onto your PDF pages to protect your intellectual property or indicate document status. Whether you want to add a 'CONFIDENTIAL' text stamp across the center of a contract or place your company logo subtly in the background, this tool gives you complete control over transparency, position, and rotation.

100% Private & Secure

Safeguarding your documents is our top priority. The watermarking process is executed entirely in your local web browser. Your sensitive files and custom logo images are never uploaded to any remote server, ensuring your proprietary documents remain safe from unauthorized access.
