Professional PDF Watermark

Protecting Your Digital Assets with Professional PDF Watermarking

In 2026, MyPDFTools.pro remains at the forefront of document security. Our online PDF watermark tool allows you to add text or logos to your documents directly in your browser. This client-side processing guarantees that your private information never reaches our servers, providing unparalleled data privacy.

The Importance of Local Processing

Most online tools require you to upload files, which can be risky for confidential documents. Our tool uses the PDF-Lib high-performance library. By processing the watermark on your device, we ensure compliance with global data protection standards like GDPR. It’s faster, safer, and completely free.

Text vs. Logo Watermarks

Text watermarks like "CONFIDENTIAL" or "DRAFT" are perfect for workflow management. Logo watermarks, however, are essential for corporate branding. We recommend using high-quality PNG images with transparency for the best visual results. Our tool automatically applies the correct opacity to ensure your branding is clear without obscuring the PDF text.

How to use this tool:

• Select your PDF file using the secure upload zone.
• Choose between 'Text Mode' or 'Logo Mode'.
• Enter your custom text or upload your brand logo.
• Click 'Apply Watermark' and download your secured file instantly.

Our tool is fully compatible with all modern browsers and mobile devices, making it the most versatile PDF protection tool available online today.
