How to Protect a PDF File
Add password protection in three simple steps
Upload Your PDF
Select a PDF file and preview the first pages before protecting it.
Set Password and Permissions
Choose the password, confirm it locally, and decide whether printing, copying, and editing are allowed.
Download the Secure PDF
Your file is encrypted on the backend, stored temporarily, and deleted automatically after 15 minutes.
Why Use Our Protect PDF Tool
Server-side encryption with practical controls for sensitive documents
Backend Encryption
The final protected PDF is created on the backend so the encryption step does not rely on browser-side production processing.
Passwords Stay Ephemeral
Passwords are used only for the live request path and are never included in audit metadata, stored job payloads, or persistent records.
Granular Viewer Permissions
Choose whether compliant PDF readers should allow printing, copying, or editing after the document is opened.
Automatic Expiry
Protected output files are scheduled for deletion after 15 minutes, and you can manually delete the secure copy sooner.
