Stamp visual restriction notices and watermarks onto PDF pages.
Runs locally in your browser
Visual restrictions only: This tool stamps restriction notices and watermarks directly onto PDF pages. It does not apply cryptographic password encryption — a determined recipient can still open and copy the file. For real encryption, use dedicated desktop software such as Adobe Acrobat or LibreOffice.
