概要

Protect PDF

Protect PDF is a feature designed to help you secure PDF files by adding password protection.

It enables you to lock a PDF so only people with the correct password can open the document.

This is useful when sharing confidential or sensitive information, such as contracts, reports, invoices, or personal records.

To use it, select the PDF you want to protect, set a password, and generate the locked version of the file.

The resulting PDF can be stored or shared with greater confidence because access is restricted.

Password protection helps reduce the risk of accidental exposure when sending documents via email, messaging apps, or shared drives.

It can also support compliance and internal policies by ensuring documents are not readable by unintended recipients.

Protect PDF is ideal for teams and individuals who regularly exchange documents that require controlled access.

Use it whenever you need a straightforward way to add an extra layer of security to a PDF before distribution.
