Password-Protect or Redact a PDF on Windows

Using encryption, password protection, or redaction on your PDF files has the utmost importance due to privacy concerns. UPDF now allows Windows users to protect their PDFs with password or redaction using the UPDF program. Read on to learn how to protect PDFs using UPDF. Or, you can also watch the video guide below.

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:

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.

5. Redact Content

UPDF provides three options for effortless PDF redaction:

1. Mark for Redaction

UPDF redaction requires two steps:

  • Mark for redaction
  • Apply redactions

To redact the text you want on the PDF file, simply choose 'Mark for Redaction' from the top menubar. After that, you can select the text which you want to redact and draw a rectangle on it. A mini quick toolbar will pop up if you click on the redaction; you can choose to Apply redaction, delete it, or view properties. Alternatively, you can just hit the Apply button on the top right corner of the interface.

2. Properties

Users can also adjust the redaction properties by pressing the 'Properties' button on the top toolbar. This particular settings feature will help you choose a color for the fill and border, which will help hide the sensitive content that you want to redact. You can also customize the overlay text on the redaction through it.

3. Redact Pages

You can also redact multiple pages at once. Select this option, and choose whether you want to redact the Current Page, All Pages, or Custom. In the case of selecting the Custom option, you will have to enter the page range in the box below. Do so, and hit the Mark button.

4. Find Text and Redact

There can be times when you may have to redact specific words or phrases on a document only. So, besides reading through the text and then redacting every time that particular word comes across, try the Search and Redact feature. Simply hit the button to operate. A small side window will pop up; you can enter the keyword to mark it for redaction, and later, you can apply redaction.
