What You Need To Know About Highlighting A PDF

Now that you're well aware of how to highlight text, it's time to look at some things to keep in mind when you do so. Here are a few things to consider:

  • Use multiple colors to differentiate things. For instance, suppose you want two different individuals to type in their names on a contract. You could draw attention to one person's responsibilities using one color and the other person's duties using another color. That way, they'll know which color is for whom.
  • Of course, you need to be super careful while highlighting text. Make sure to accentuate only those elements you want to draw attention to. That's because over-highlighting can make your document less attractive.
  • Whenever you highlight a part of your text, save it to ensure that your revisions are safeguarded.
  • The resulting file will contain the colors you've used. For example, if you've used the colors "red" and "yellow" to draw attention to parts of your file, the final document will have those colors.


Using an online tool to highlight a PDF file is always the best option. However, there are times when you might want alternatives for various operating systems like Windows, Mac, Linux, Android, and iOS. So, we'll now talk about these in detail.
