Part 4. White Out PDF Offline(2 Ways)

The only benefit of using online tools to whiteout PDF documents is that you can use them on the go. On the other hand, there are multiple limitations like waiting in queues, file size limitations, reliability issues, etc. One solution to all these issues is using UPDF since it works offline. You can use this tool on the go as well since it is available on computers and smartphones.

When you use UPDF to whiteout PDF documents offline, you can use 2 methods: one is Redaction, and the other one involves adding a shape on top of the content in PDF documents. This part contains details and guides about both these methods so you may use them effortlessly.

Way 1. White Out PDF using Redaction

Redaction is the most reliable way of removing contents from a PDF document, so if you need to remove data permanently, you can use it. Remember that Redaction is permanent. So, you cannot get the information from that section back once you redact a PDF document. Similarly, no one else can search for or recover that information.

Step 1: Launch UPDF on the computer by double-clicking the desktop icon, then opening the PDF with "Open File" before you click "Redact." You will see a popup window that shows 2 steps for redacting that you need to "Accept" before proceeding with its steps.

Step 2: To redact a specific part in a PDF document you will select "Mark for Redaction" from the top then use your cursor to mark a specific area in a PDF document. The area that will be redacted will become black.

As you do not need the black color, you can change the properties. Right-click on the redaction part, and select "Properties".

Step 3: In the pop-up window, select "White" color, and to save redaction changes, you need to click "Apply" from the top right, then click "Continue" and save the PDF document. Once you save PDF the content under the redacted area can never be recovered or searched.

Way 2. White Out PDF Using Shape

Say that you want to hide some information from a PDF document, but you don't want to permanently remove it. That's where you can use a shape and cover the information in PDF. It is better for the cases when you may need the information back since you can get that back by simply editing or removing the shape from its location.

To ensure that this shape blends in perfectly with the document and contents under it get completely hidden, you must match the fill and border color of that shape with the color of PDF page.

Step 1: Click the shape option from the top select the rectangle shape with your desired border, and fill color. It is recommended to keep both these colors the same as the color of your PDF page.

Step 3: Click and drag the cursor over the content to hide it and once you have covered all sensitive content, you may save the PDF. Remember that this shape can be edited and removed in PDF, which will reveal sensitive information under it.
