How to Use PDF Password Protection
Upload a PDF file, enter a password and confirm it, then click "Protect PDF" to download a password-protected version of your document.
Current Status
PDF password encryption is a planned feature. It requires low-level encryption algorithms (AES-256 / RC4) that are not yet available in browser-based PDF libraries. We are working on adding WebAssembly-based encryption support in a future update.
Privacy
When available, all encryption will happen entirely in your browser. Your files and passwords will never be sent to any server.
