Password Protect PDFs

Using encryption or password protection on your PDF files has the utmost importance due to privacy concerns. UPDF now allows Windows users to password-protect their PDFs using the UPDF program.

1. Add an Open Password

The first encryption feature that UPDF offers is to add an open password to your PDF file. Here is how to do it:

  • Open your PDF file in UPDF.
  • Click on the Protecting Using Password icon on the right panel of UPDF.

  • Now select the Document Open option.

  • Type your password in the given fields.

  • You can also change the level of protection by clicking on the More options button (The security levels include: 128-bit RC4, 128-bit AES, and 256-bit RC4)
  • Now click on Apply.

  • In the new pop-up, click Save to save the encrypted file with an open password.

2. Add a Permissions Password

A permissions password (also known as a master password) requires a password to change permission settings. Using a permissions password, you can restrict printing, editing, and copying content in the PDF.

Here is how to add a permission password to your PDF document:

  • Select the Permissions after clicking the Protect Using Password icon.

  • Save the encrypted file.
