Allowing you to draw attention to the important information, highlighting a PDF makes reviewing and digesting materials much easier. However, it is not always clear how to highlight a pdf. Fortunately, the instructions in this detailed guide will show you how to add highlights to all types of PDF files.
1. Why can’t I highlight my PDF?
It is not uncommon for PDF users to deal with the “PDF won’t let me highlight” issue. If you can’t select text in PDF, the reason could be one of the following:
- You are dealing with a scanned document.
- The PDF file is secured.
First, go ahead and open your PDF file and scroll down to where the image you want to capture is located. Next, click the Edit menu and select Take a Snapshot. At this point, you could simply click and drag your mouse over the area of the image to capture a screenshot, but a better way is to click on the Edit menu again and choose Select All.

All you have to do is open the scanned document or image that you'd like to OCR, then click the blue Tools button in the top right of the toolbar. In that sidebar, select the Recognize Text tab, then click the In This File button. Here's how to highlight in a PDF in Adobe Acrobat: Open the PDF (you may need to right-click and select Open With. To select Adobe Acrobat). Click on Comment in the right-hand tool bar. Click on the Highlight Icon that appears at the top of the window. Highlight your text. Save the document. Click the Home tab. Click the Rectangle Tool. Click and drag the pointer to determine the dimensions of the highlight: Click the Format tab, then click the Fill Color dropdown menu to select a color for the highlight.

If the PDF file originates from a scanned piece of paper, then the reason you can’t select text in PDF is that there is no “text” to highlight or select. A scan is an image of the original piece of paper. If you are wondering how to enable highlighting in PDF originating from a scanned paper, you may need to work with a PDF tool that has the OCR (Optical Character Recognition) feature. The OCR feature will help you convert the image of the text in your scanned PDF into a highlightable/selectable text.
If your PDF file is not scanned but you still can’t select text in PDF, chances are, the file has security that prevents editing. You can’t highlight a secured PDF. If you are using Adobe Reader, you can check whether the document is secured by clicking on File > Properties and then select the Security tab.

With the right tools, however, you can eliminate this problem. Below, we will show you how to enable highlighting in PDF formed through scanning.
Use OCR tool
To use this option, you will need to have a tool with the Optical Character Recognition (OCR) feature installed on your computer. One such tool is Adobe Acrobat X. The instructions below will show you how to enable highlighting in PDF using this tool:

Without OCR tool
It is still possible to mark up text in a scanned PDF without having to use the OCR tool.

Step 1: Open the scanned PDF file in Preview.
Step 2: At the top of the page, click the Pen icon. This should give you the annotations toolbar.

Step 4: Go to the Line Thickness sub-menu and select the first thickness option – this should be the thinnest option in the list.
Step 5: Go to the Color sub-menu and select your preferred color.
Step 6: To highlight a section of the scanned PDF file, simply place the cursor at the beginning, hold down the left mouse button and then drag the cursor over the preferred section. This should draw a rectangle around the section.
Note: If you would like to say something about the highlighted text, simply go to the Text box submenu and then choose a Thought Bubble, Speech Bubble, or the regular Text Box. Next, draw this next to the highlighted text and then type in your text.
Step 7: To save the highlighted document, go to File > select Save.
6. Highlight texts in locked PDF

As noted earlier, you can’t highlight a secured PDF. Most locked PDF files will deny you the ability to edit them. This means that the only thing that you can do is just view them.
The only way to enable highlighting on a secured PDF document is by using a password to unlock the file. If you know the person who locked the file, contact them, and request a password. If you get the password, follow the steps outlined below to unlock the file:
Step 1: Open the file in Acrobat.
Step 2: Go to File > Properties > Security.
Step 3: Choose No Security.
Step 4: You will be prompted to enter the password. After entering the password, save the PDF file and then close it.
Once you open the PDF document again, it won’t be locked. This means that you will have the ability to highlight it. Depending on the software you intend to use on your computer, you will simply need to follow the steps we have outlined above.
