Watermark PDF

Overview

Adding a watermark helps identify ownership, prevent unauthorized distribution, and brand your documents. Our Watermark PDF tool lets you stamp text or image watermarks onto any PDF with full control over position, size, opacity, and rotation.

How It Works

1. Upload the PDF you want to watermark.
2. Enter your watermark text or upload a watermark image.
3. Adjust position, opacity, font size, and rotation.
4. Apply the watermark and download the result.

Common Use Cases

• Mark draft documents to prevent unauthorized use.
• Brand reports, proposals, or presentations with a company logo.
• Add 'Confidential' or 'Sample' stamps to sensitive files.
• Deter copying of copyrighted content.

Tips for Best Results

• Use 30–50% opacity to keep content readable.
• Center diagonal watermarks work best for full-page coverage.
• Test on a single page before applying to a large document.

Frequently Asked Questions

Can I use an image as a watermark?

Yes, you can upload a logo or image file to use as a watermark instead of text.

Will the watermark be removable?

Watermarks added this way are embedded in the PDF and are difficult to remove without the original file.
