PDF Watermarker
Add watermarks to PDFs in your browser
What is PDF Watermarker?
PDF Watermarker is a free, browser-based tool that lets you add professional watermarks to your PDF documents without uploading your files to any server. Your documents remain completely private as all processing happens locally in your browser. Whether you need to mark documents as "CONFIDENTIAL," add your company logo, or insert draft stamps, this tool provides flexible options for both text and image watermarks with full customization of opacity, rotation, position, and page selection.
How to Use It

Upload a PDF file by dragging and dropping or clicking the upload area. Your file never leaves your browser.

Adjust opacity, rotation, position, and other settings to match your needs. Use the tiled option for repeating patterns.
