About PDF Watermark Add Tool

​Protecting your digital documents is more important than ever. Our Professional PDF Watermark Tool is a high-speed, browser-based utility that allows you to overlay custom text watermarks onto your PDF files instantly. Whether you are a student protecting your assignments or a job seeker on portals like Assam Career Path wanting to mark your documents as "FOR OFFICE USE ONLY," this tool provides a 100% secure and offline solution.

​Unlike other online tools, our watermark generator processes everything locally on your device. Your sensitive documents are never uploaded to any server, ensuring your data remains completely private and secure.

​Key Features of Our PDF Watermarker:

​Full Page Coverage: The tool automatically applies your custom watermark to every single page of the uploaded PDF document.

​Complete Customization: You have full control over the Font Size, Color, Rotation, and Opacity (transparency). Make it as subtle or as bold as you need.

​100% Privacy & Offline: Since the processing happens in your browser, the tool works even without a strong internet connection once the page is loaded.

​Universal Compatibility: Works perfectly with PDFs generated from Word, Scanners, or Mobile cameras.

​Mobile Friendly: Designed with a responsive interface that works smoothly on Android, iOS, and Desktop.
