Add password protection to PDF files.
Supported formats: PDF
Our PDF Protect tool allows you to add password protection to your PDF documents. You can set a user password that's required to open the document, an owner password that restricts permissions, or both. This is useful for securing sensitive documents, protecting intellectual property, or controlling who can edit or print your PDFs. All processing happens directly in your browser - your files never leave your computer, ensuring maximum privacy and security.
All password protection is performed directly in your browser. Your passwords and documents are never sent to our servers, ensuring maximum privacy and security. However, please note that PDF password protection has limitations and can be broken by specialized software. For highly sensitive documents, consider using additional security measures.
