PDF Password Protector
Add password protection to PDFs. Free, no signup, no upload.
How It Works
Select a PDF file and enter a password. Click Protect and the PDF is encrypted so that anyone opening it must enter the password first. No file is ever uploaded to a server.
Why Password Protect a PDF?
Password protection prevents unauthorized access to sensitive documents like contracts, financial statements, medical records, and confidential reports. The recipient must know the password to open and view the file.
