PDF XChange Editor is a popular tool for viewing and editing PDFs. One of its key features is the highlight tool. It makes it easy to point out important details or review documents.
But if you tried using the highlight feature in full-screen mode, you likely ran into a problem. It simply isn’t there! This means switching back to windowed mode whenever you need to highlight text. This can get frustrating really fast.
So, can PDF XChange Editor full-screen mode highlight text? This guide explains it in detail. Plus. You'll also learn how to add, remove, and troubleshoot highlights in the windowed mode.
Let’s get started.
Part 1. Can PDF XChange Editor Full-Screen Mode Highlight Text?
Yes, you can highlight text in PDF XChange Editor while in full-screen mode. However, this feature is turned off by default. The full-screen mode in PDF XChange Editor is designed as a presentation mode by default. This means you can only view and navigate through the pages. In this default state, you cannot use PDF XChange Highlight or other editing tools.
To enable highlighting in full-screen mode, you need to disable the presentation mode in the preferences. After that, the highlights and annotation features will still be accessible when you switch to full screen.
Here’s how to highlight in PDF XChange Editor full-screen mode.
Step 1. Open PDF XChange Editor and import your document. Then, press the “CTRL + K” keys on your keyboard to open the Preferences panel.
Step 2. Select “Full Screen” from the left. Then, under the Page Navigation section, uncheck “Presentation Mode.” Then click “OK.”

Step 3. To enter full-screen mode, press “F11” on your keyboard. Otherwise, click the Full Screen mode option in the top right.

Step 4. Once you’re in full screen, right-click the page. Then, choose “Select Text.”

Step 5. Select the text you want to highlight. Then, right-click and choose “Highlight Text” from the context menu.

Part 2. How to Highlight Text in PDF XChange Editor?
The full-screen mode in PDF XChange Editor offers only the basic highlight tool. Apart from this, it offers three useful ways to highlight text in the regular windowed mode. In this mode, you can highlight individual text, use the freehand, or the PDF XChange Editor highlight area tool. However, these tools aren’t visible on the Home screen. If you’re wondering how to access and use them, follow the steps below.
Step 1. Open your PDF in PDF XChange Editor. Then, select “Comment” from the top menu.

Step 2. In the Text Markup section, you will see three highlight tools:
- Select the “Highlight Text” option. Then select your desired text. Once you release the cursor, the highlight applies automatically.

- Choose the “Highlight Area” mode. Then click and drag to select the area you want to highlight.

- Go with the “Free Highlight” tool. Then click and drag your cursor over your desired text to manually draw the highlight.

Part 3. How to Remove Highlight in PDF XChange Editor?
Sometimes, you may not be satisfied with a highlight or you might need to clean up your document before sharing it. In that case, PDF XChange Editor makes it easy to remove highlights. You can delete them one by one or clear multiple highlights at the same time.
Here’s how to use PDF XChange Editor to remove highlights.
Step 1. Navigate to the place where you've added the highlight. Click on it to select it. Now you can delete it in two ways:
- Press “Delete” on your keyboard to remove the highlight.
- Right-click the highlighted area. Then, select “Delete” from the context menu.

Step 2. You can also remove multiple highlights at once. To do this, press the “CTRL” key and click on all the highlights to select them. Then, press the “Delete” key. Alternatively, right-click the selected highlights and choose “Delete” from the menu.

Part 4. PDF XChange Editor Highlight Text Not Working
If the highlight tool still isn’t working even after following the steps above, the issue may be with the document or the program itself. Here are the most common reasons behind it.
- Scanned PDF: You might be working with a scanned or image-based PDF. The highlight tool does not work on images because you cannot select the text. In this case, use the built-in OCR feature to convert it into editable text.
- Print to PDF: When you print a web page to PDF, your browser converts text into shapes instead of fonts. This prevents you from selecting and highlighting text. To solve this issue, you can run OCR on the file to recognize the text.
- Software Bugs: The highlighting issue may be due to bugs with the software itself. If so, update your program to the latest version to fix any underlying errors. This can help you use all annotation tools normally.
