Why Add a Watermark to Your PDF Documents?
Watermarks are essential for protecting your intellectual property, establishing brand identity, and preventing unauthorized distribution. Whether you're a photographer sharing proofs, a business sending confidential proposals, a teacher distributing worksheets, or a designer showcasing portfolios, adding a visible watermark ensures your work remains attributed to you.
Text Watermarks vs. Image Watermarks
Text watermarks are ideal for adding words like "Confidential", "Draft", "Sample", "Review Copy", or your company name and website. You can customize font family, size, color (with hex picker), bold/italic/underline styling, and rotation angle. Image watermarks work best for company logos, signatures, stamps, or visual branding elements. Both types support opacity control (from subtle 10% to strong 100%) and precise positioning via drag-and-drop.
Complete Customization Options
- Position & Alignment: Choose from 5 preset positions (center, top-left, top-right, bottom-left, bottom-right) or manually drag the watermark anywhere on the page.
- Opacity Control: Fine-tune transparency from 0.1 (barely visible) to 1.0 (fully opaque).
- Rotation: Rotate watermarks from -180° to 180° in 15° increments for diagonal or angled placement.
- Page Range Selection: Apply watermarks to specific pages (e.g., pages 2-10 only) or all pages by default.
- Batch Processing: Upload multiple PDF files at once and add watermarks to all of them simultaneously.
