How the PDF Watermark Tool Works
The watermark tool processes PDF files locally inside your browser using client-side technology. When you upload a document, the file is read on your device and a watermark layer is applied to each page without sending data to any external server.
You can add a custom text watermark or upload an image such as a logo or signature. The watermark position, rotation, opacity, and size can be adjusted so it remains visible while not blocking the document content.
The final PDF keeps its original layout and quality. Only the watermark is added. Because the processing happens locally, your documents remain private and the finished file can be safely shared, printed, or archived.
Custom Text
Add labels such as Confidential or Approved.
Image Logo
Upload a logo or signature as a watermark.
Private Processing
Files remain on your device and are never uploaded.
