Files360 PDF Password Protect provides a secure, browser-based way to add or remove password protection from PDF documents. In an era of increasing data privacy concerns, protecting sensitive PDF files before sharing them via email, cloud storage, or messaging is essential.
The tool supports two protection modes: adding password protection to secure your documents, and removing existing protection from PDFs you have authorized access to. When adding protection, you can set separate user and owner passwords, and configure granular permissions for printing, copying, and modification.
Privacy is fundamental to our approach. Unlike cloud-based PDF protection services that upload your files to remote servers, Files360 processes everything locally in your browser. Your PDF content and passwords never leave your device, making it ideal for protecting confidential business documents, legal agreements, financial records, and personal files.
The password strength meter provides real-time feedback as you type, helping you create strong passwords that resist brute-force attacks. We recommend using 16+ characters with a mix of uppercase, lowercase, numbers, and symbols for maximum security. The tool is completely free with no usage limits or watermarks.
