Highlight a PDF and Remove Highlights: Full Guide
PDF is a very common format to keep documents in. When sharing such files with others, you may need to leave comments or highlight text in your PDF.
This article will walk you through the process of how to highlight a PDF, pointing out specific text or an area of content. We will also discuss how to remove highlighted text in the PDF that was created by someone else.
Additionally, the article will answer a few common questions associated with these two tasks.
How we picked products
For this article, we picked programs for two operating systems - free PDF editor for Windows and for macOS.
The chosen PDF editing software is free, easy to use, and offer all the needed tools to add and remove highlight from a PDF. Additionally, each of the software has other features to enhance your experience when working with documents in this format.
How to highlight a PDF on Windows?
To mark certain parts of the content in color, you will need a special PDF highlighter. One such program for Windows computers is the Icecream PDF Editor. This software allows you to highlight PDFs along with the ability to add the description for each annotation and pick a color.
See the detailed instructions on how to highlight on a PDF with the application below:
1. Download the software
Go to the website and download the PDF editor. Double-click the installation file to launch the setup process. Open the PDF highlighter to proceed.
2. Upload your file
Drag and drop the PDF document into the program's window to open it.
Alternatively, use the "File" menu's "Open..." option or the "Open..." button in the center of the working window. Browse the file on your computer.
3. Choose the tool
Click the "Annotate" button on the PDF highlighter's upper-left-hand side to switch the mode.
There are two highlight PDF tools offered. The first one is the "Highlight area" to call attention to any selected part of a PDF page.
The second one is "Highlight text" to accentuate the written content of the PDF only. Pick the one that suits your needs best.
4. Highlight your PDF
Select the color of the PDF highlight. You can select one of the default colors or add a custom shade of your own. Hover the mouse cursor over the area or text you wish to highlight on the PDF.
To highlight an area in a PDF, left-click the mouse, hold it, and move around the page to select the desired part. Release the mouse button once the selection is done. You can proceed to another part of the document right after the previous highlight – you don't need to select the tool again.
To spotlight written content only, complete the same procedure but after selecting the "Highlight text" instrument.
Once the PDF is highlighted, you have the option to add an annotation to PDF, describing each highlight. You can find the corresponding tool on the left vertical panel.
How to undo highlighting in a PDF?
Removing existing PDF highlights that were done by someone else is also possible with the same free PDF editor.
If you need to remove a highlight from a PDF you received, open the file with the program. Select the highlighted areas and then hit the "Delete" button on your keyboard.
Another way to remove a highlight in a PDF is to open the "Annotations" panel using the button on the right-hand side of the program's interface. You will see the list of all the annotations.
Select the page number of which highlight you wish to remove. Right-click it and hit the "Delete annotation" option from the newly opened context menu.
How to highlight a PDF on a Mac?
For macOS users, there is no need to search for a specialized PDF highlighter. Apple devices are equipped with a built-in application Preview that is capable of highlighting text in a PDF.
See the description below for how to highlight text on a PDF with this software.
1. Open the PDF
Open the PDF to highlight the program. If Preview is not selected as your default application for PDF files, right-click the document and choose the "Open with" option. From the dropdown menu, pick the needed program.
2. Choose the tool
At the top of the app's window, locate the "Highlights and Note" icon (the pencil-looking one). Click on it to choose the instrument. Hit the arrow-down icon to the left of the tool to pick the PDF highlighting color.
3. Make annotations
Begin to highlight your PDF. Select the text you need to be spotlighted with the left button of your mouse. Move until all the needed PDF content is highlighted. Release the mouse.
Undo PDF highlights
To remove the highlight from the PDF that you did mistakenly, go to the "Edit" menu and choose "Undo add highlights". Alternatively, hit the Command + Z hotkey combination on your keyboard.
To delete the highlight on a PDF that was done by another user, select the area of the text and pick a different color. Select the same area again to get rid of the selection.
Why can't I highlight text in a PDF?
When working with PDFs you need to annotate certain elements and cannot do that, it is very frustrating. Instead of why you are not able to select text or other content and highlight it in a PDF, think about what causes the issue.
Most commonly, the reason you are unable to use a PDF highlighter to annotate or otherwise edit a PDF is that you are working with a scanned document. Your document is not a textual file. It is a collection of images, and the PDF reader or editor cannot recognize its context as text.
To be able to make annotations to such a file, you will have to convert it to an editable document first. Most likely, you will need to use an optical character recognition (OCR) tool to extract the text.
Why would I need to highlight a PDF?
Utilizing a PDF highlighter is an effective method of emphasizing vital components of a document. It can also help you keep track of the information you are reading.
Reasons to highlight a PDF:
- Organize Information. PDF highlighting helps organize content by making it easier to read and comprehend. You can quickly identify key points in the document without needing to peruse the entire text. This can save you time when reviewing or studying material.
- Make Notes. When you highlight text in a PDF, you can make notes next to it for quick reference. These notes can be used as reminders or additional information about the highlighted item.
- Review Material. Highlighting makes it easy to scan through the material rapidly and efficiently. You can easily scan through the document and note the main points without having to read the entire text again.
- Search for Information. Many viewers have the capacity to search for a word in a PDF. This allows users to quickly find specific words or phrases within a document. If you highlight important terms or concepts, it will be even easier to find them using these search tools.
- Share Information. When you highlight content on a PDF, it allows you to quickly and easily disseminate important data to others. You can highlight passages and then email or post them online for others to view and reference.
- Make Connections. PDF highlights help you link disparate points in a document. For example, if you are reading an article about climate change, you might highlight specific facts that link back to each other or draw parallels between different sections of the text.
Knowing how to highlight on a PDF is a useful skill to organize your thoughts, review material quickly, share information with others, and make connections between different points in a document. By using the highlight PDF tool, you can save time and become more efficient when studying or researching any type of material!
