Protect Your Intellectual Property
Sharing documents online can be risky. Without protection, your work can be copied, altered, or claimed by others. The Utilix Watermark tool is the easiest way to claim ownership of your PDF files. By adding a stamp like "Confidential," "Draft," "Sample," or your own Company Logo, you ensure that anyone viewing the file knows its source and status.
Our tool offers professional-grade customization. Unlike basic tools that just slap text in the center, Utilix lets you control the transparency and rotation. This is crucial for creating subtle background watermarks that discourage copying without ruining the reading experience. Best of all, the process is 100% free and private—your watermarked files are yours alone.
