How to Add or Remove Watermarks in PDF Files Securely
Protecting intellectual property with custom "CONFIDENTIAL", "DRAFT", or corporate logo watermarks is essential for business documents. Similarly, cleaning or removing unwanted draft stamps is frequently required before publishing final reports. Traditional online tools require uploading private contracts and reports to remote cloud servers, creating security risks.
Our advanced **Client-Side PDF Watermark Utility** processes your files locally right inside your web browser. Using high-performance JavaScript engines (`pdf-lib` and `PDF.js`), text or image stamps are embedded or filtered out directly on your machine without any external data transmission.
