How it works
Your PDF is encrypted using standard PDF password encryption (RC4 128-bit). This is the same encryption used by Adobe Acrobat. Every PDF reader will require the password to open the file. All processing happens in your browser — your file and password never leave your device.
Remember your password
There is no way to recover your PDF if you forget the password. Store it safely.

PannaPDF's Protect tool adds native PDF password encryption to your files using industry-standard RC4 128-bit encryption. Your files and passwords are never sent to any server — all processing happens entirely in your browser. The protected PDF will require a password in any PDF reader including Adobe Acrobat, Chrome, Firefox, Apple Preview, and more.
