Add a password to a PDF so it requires that password to open, with optional restrictions on printing and editing -- free, no signup required
Our free tool to protect a PDF adds a password to a file you choose, so it requires that password to open. You can also restrict printing or editing, so a copy can be viewed but not easily changed or printed. Free to use, with no watermark added to your pages.
Drag and drop the file into the box above, or click to browse and select it from your device.
Type the password you want to require for opening the file. Optionally check restrictions for editing or printing.
Download a copy that now requires your password to open. Your file is processed securely and deleted within 30 minutes.
Uses AES-256 encryption, the modern standard for PDF passwords.
Limit printing or editing independently of the open password.
No trial, no watermark added to your pages.
Your file and password are handled over an encrypted connection and deleted within 30 minutes. We never store passwords.
Upload the PDF to the tool above, type the password you want to set, and download the protected copy. The file will then require that password to open.
