Introduction

Highlighting text in PDF documents is a common practice in both educational and professional settings. Students highlight key information in academic articles, e-books, and class notes to facilitate study and review.

Similarly, professionals use highlight to add marks to crucial data in reports, contracts, and other official documents. The ability to highlight text in PDFs is essential because it allows users to interact with content in a meaningful way without altering the original document.

It may seem that highlighting a PDF is simple, but not all PDF editing software offers tools that give good results when underlining text in a PDF. This is where PDFBeast comes in.

In this article, I will explain in detail how to highlight a PDF with PDFBeast and give you a few tips to ensure that the final result is as good as you expected.

Highlighting text is very common in digital documents, and while you could print the PDF, highlight it by hand using a highlight marker, and scan it back in, this is a tedious task and the results are not great.

Tips and Best Practices for Highlighting PDFs

In conclusion, now that you know how to highlight in PDFs, I'd like to share some tips and best practices for highlighting PDFs.

While highlighting a PDF might seem easy, highlighting it practically and efficiently isn't. Here are some tips I think you should apply:

Consistency in highlighting

Use consistent colors and highlighting styles throughout your document.

For example, you can use one color for definitions, another for quotes, and a third for key concepts. This makes it easy to quickly identify different types of information.

Keep in mind that you can even change the text color in your PDF.

Don't over-highlight

Often, everything in a text seems important.

Adding highlight with too much text can be counterproductive and cause important information to get lost among the highlighted lines. Be selective and highlight only what you really need to emphasize.

Add notes to the text

Highlighting may not always be enough to highlight parts of the text.

Thanks to PDFBeast, you can add annotations and comments that provide additional context and clarify why certain parts of the document have been highlighted.

Here's how to add notes to your PDF.

Review the final document

Before downloading the highlighted PDF, review the document.

This way, you can make sure everything is consistent and that you haven't skipped any parts of the text. If needed, remember that you can easily delete text from the document.
