What Protect PDF will do
Set a password to open the PDF, and optionally restrict printing and copying. Encryption happens on your device, so your password never reaches us.
Your files never leave your device
PDFSleek runs the editor inside your browser. Your PDF is opened, edited and saved on your computer — it isn't uploaded to us, so there's nothing for us to read, keep or lose.
- Processed in your browserNo uploads while you edit.
- Encrypted connectionHTTPS everywhere.
