Professional Watermarking Made Simple

Protect your intellectual property and confidential documents with ease. Our free online tool allows you to add custom text watermarks to your PDF files instantly. Whether you need to stamp "Confidential", mark a "Draft", or add your company name, we provide the tools to do it professionally and securely. Security is our top priority. Unlike server-side tools, our watermarking process runs entirely in your browser using WebAssembly. This means your private files are never uploaded, stored, or shared with anyone else.

Full Customization

Precise control over your watermark. Adjust rotation, opacity, font size, and color to perfectly match your branding.

Private Processing

Your sensitive contracts and documents never leave your computer. Watermarking happens entirely in your browser.
