UPDF PDF viewer and editor is the best choice for unchecking a box in PDF documents, whether that check box is interactive or not. UPDF supports directly unchecking interactive check boxes, but if the check box is not interactive, it can be unchecked by covering it with a rectangle for non-fillable PDF forms.

Each method of unchecking a box in PDF with UPDF requires different steps, so click the below button and follow our comprehensive guide on all these methods:

Way 1. How Do I Uncheck a Box in a Fillable PDF?

The first way UPDF can be used is for the PDF forms that are made fillable. These forms do not require any special tools or methods to uncheck a box, and simply clicking a box will uncheck it. So, you may follow these steps with UPDF to uncheck boxes in fillable PDF documents:

1. Open PDF in Reader Mode UPDF

Download UPDF on your computer. Double-click the fillable PDF file to open it in Reader view in UPDF, and since your PDF form is fillable by default, you can check and uncheck boxes in the reader mode without using any additional tools.

2. Click to directly uncheck a box in PDF.

Click the check box, and it will be unchecked instantly. This way, you can uncheck checkboxes and unselect radio buttons. The only requirement you must meet is to have a fillable PDF document.

So, download UPDF and work on fillable PDF forms easily using the steps above.

Way 2. How to Uncheck a Box in a Fillable PDF Form Via Adding New Check Box?

If you are working with a fillable PDF form but, due to certain reasons, the check box cannot be unchecked, you can use UPDF to add another check box on top of the previous one. The new check box will be interactive, and it can be used like a normal check box in PDF forms. Since it covers the old check box, you don't need to worry about it being interactive or not. Follow the steps below to add a new check box for unchecking the previous one:

1. Open PDF in UPDF Prepare Form mode

Start by downloading UPDF on your PC and set it as your default PDF tool. Double-click a PDF file to open it in UPDF and click the "Prepare Form" button from the left pane menu. Since you are adding a new check box, it needs to be in Prepare Form mode, as the PDF will open in Reader mode by default.

2. Click the Check Box button from the top to add a check box

In the Prepare Form mode, there are multiple fillable form options. You need to look for the "check box" option. Now move the cursor to the PDF page and click to add a check box. The check box may not be of the same size.

3. Carefully resize and position the check box over the previous one

Now, you need to click and drag the check box to move it over the previous check box. Using the edge markets, you need to resize the check box so that it is of the same size as the check box under it, or it can be slightly larger so it covers the previous one. Once you have positioned it, you can save the PDF document and make it a fillable form once again.

Way 3. How to Uncheck a Box in Non-Fillable PDF Form Via Adding Rectangle Shape

Sometimes, you have a PDF form where the check box does not function like normal. It is because the form is not fillable, so if you have a check box that is checked, there may seem no solution to uncheck it. Such PDF forms are usually designed for printing and filling using a pen. So, adding a rectangle over the check box using the annotation function will be the best solution to uncheck that check box. You can do that by following these steps with UPDF:

1. Open PDF and go to Comment in UPDF

Download UPDF and open it by double-clicking its icon. Use the "Open File" button to open the PDF document and select the "Comment" option from the left side menu.

2. Click the shape tool.

Click shape option from top, and here, we will choose rectangle. We may also choose the right color for boundary and to fill in it.

3. Click anywhere to create the rectangle.

Click anywhere on the page to create a rectangle. Click slightly away from the check box for easier resizing.

4. Carefully resize and position the rectangle to cover the box

Hold the click and drag the rectangle over the check box to position it correctly. Secondly, you need to ensure it is of perfect size by using the edge markets on the rectangle and resizing it. The new rectangle must be big enough to cover the previous non-fillable check box.
