What Do You Need To Know About Highlight A PDF

Now that we're well aware of how to highlight a PDF file, it's time to look at some of the critical aspects of highlighting a document. Here are a few things that you need to consider while highlighting a PDF file:

  • It's always good to use multiple colors while highlighting your PDF file to differentiate things. For instance, suppose you want two different individuals to type in their names in a contract; you can highlight one person's responsibilities using color and the other person's duties using another color. That way, they'll know which one is for whom.
  • Of course, you need to be super careful while highlighting your PDF file. Make sure to highlight 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 PDF file, save it to ensure that your revisions are permanent.
  • The resulting PDF file will contain the colors you've used to highlight your document. For example, if you've used the color "Red" and "Yellow" for highlighting your file, the final PDF will be the same.
