  1. Open the free Protect PDF tool and upload your PDF.
  2. Choose Protect. Enter the password needed to open the file, and optionally a different owner password for permissions such as printing and copying.
  3. Download the protected PDF, then open it once with the password to confirm it works before you send it.
  4. To remove the password later, use the Unlock mode on the same page and enter the current password.

Frequently asked questions

What encryption is used?

AES-256, the standard used for sensitive documents.

What is the difference between the user and owner passwords?

The user password opens the file. The owner password controls permissions such as printing and copying. If you leave the owner password blank, it uses the same password as the open password.

What if I forget the password?

It cannot be recovered. There is no backdoor and no reset link, so keep an unprotected copy somewhere safe.

Can I remove a password from a PDF?

Yes. Use the Unlock mode on the Protect page and enter the current password.
