About Protect PDF

Secure your critical documents with our PDF Password Protector. Whether you want to prevent unauthorized opening of a file or simply wish to stop people from printing or editing your work, this tool provides a comprehensive security solution. We support two levels of protection: "User Password" (required to open the file) and "Owner Password" (required to change permissions). You can granularly control actions like printing, copying text, modifying content, and filling forms. All encryption is performed on our secure servers using industry-standard protocols, ensuring your sensitive data remains protected from unauthorized access.
