Watermark PDF Online
Loading tool...
Whether you are distributing confidential memos, draft manuscripts, or proprietary reports, adding a watermark ensures your documents are properly attributed. This tool is built to stamp text across every page of your PDF.
Client-Side PDF Modification
The tool leverages pdf-lib to parse your document's binary structure. It loops through every page, generating a new text or image layer at the specified opacity and angle, and re-saves the file.
Confidentiality Guaranteed
Because PDF documents often contain sensitive business data, they should never be uploaded to third-party servers. This utility processes the watermark natively in your browser, keeping your documents completely private.
