PDF Watermark

Add a text watermark to all pages of a PDF document.

PDF Watermark Tool – Add Text Watermarks to Documents

Protect your PDF documents and indicate ownership by adding text watermarks. The PDF Watermark tool allows you to overlay customizable text watermarks across all pages of a PDF, with control over text, size, opacity, and rotation angle.

Perfect for marking documents as "CONFIDENTIAL," "DRAFT," "SAMPLE," or adding copyright notices, all processed securely in your browser.

Why Add Watermarks to PDFs?

PDF watermarks serve several important purposes:

  • Document Protection: Mark documents as confidential or draft versions
  • Copyright Indication: Add ownership or copyright notices
  • Status Labels: Indicate document status (DRAFT, APPROVED, etc.)
  • Branding: Add company names or logos as watermarks

Customization Options

1. Watermark Text

Enter any text to use as your watermark. Common examples include "CONFIDENTIAL," "DRAFT," "SAMPLE," copyright notices, or company names. The text appears diagonally across pages.

2. Font Size

Adjust font size from 10 to 200 pixels. Larger sizes are more prominent, while smaller sizes are more subtle. Recommended range: 40-80 pixels for most documents.

3. Opacity Control

Set opacity between 0.1 (very faint) and 1.0 (fully opaque). Lower opacity (0.2-0.4) ensures the watermark doesn't interfere with document readability while still being visible.

4. Rotation Angle

Rotate watermark text from 0° to 360°. A 45° angle creates a classic diagonal watermark, while other angles offer different visual effects. The watermark appears centered on each page.
