About the Watermark PDF Tool
Stamp an image or text over your PDF in seconds. Choose the typography, transparency and position. The Watermark PDF is part of UnCloud's powerful suite of PDF & Documents utilities. We designed this tool to give you full control over your data without ever compromising on your privacy.
100% Client-Side Processing
Unlike conventional online tools that force you to upload your sensitive files to a remote server, UnCloud processes everything directly in your browser. This means zero data uploads, zero waiting times, and absolute privacy. Your files never leave your device.
