Watermark PDF Online Free
In today's digital world, protecting your documents is more important than ever. Whether you are sending a confidential business proposal, sharing your creative portfolio, or submitting an academic assignment, you need a way to claim ownership. That is exactly what this PDF Watermark Tool helps you do. It allows you to add a custom text or logo watermark to your PDF files instantly, right from your browser.
The best part about this tool is its simplicity and security. Most other websites ask you to upload your files to their servers, which can be risky for sensitive documents. However, our tool processes everything locally on your device using advanced browser technology. Your files never leave your computer or phone. You can customize every aspect of your watermark—choose from over 25 stylish fonts, adjust the transparency to make it subtle, rotate it to any angle, or tile it across the entire page for maximum protection. It is completely free, works on both mobile and desktop, and creates high-quality watermarked PDFs ready for sharing.
