Most electronic documents are saved in PDF format these days, especially the files with lengthy documents. While PDF is a great tool, there are instances when you have to deal with the issues of not being able to highlight important information in PDF eBooks and other materials when reading for future reference. Many readers, including Adobe, will only allow users to highlight files if they have rights to the document. Here we would like to share the easy solution on how to highlight PDF easily.

Part 1: How to Highlight PDF Files on Mac Using PDF Highlighting Tool

If you are having problem with highlighting a PDF on Mac, you could opt for a program called iSkysoft PDF Editor for Mac. This is an all-one tool for Mac and it has the capabilities to convert, annotate, edit or highlight PDF text easily.

You can easily highlight PDF texts on Mac with a selected color. Just click the "Highlight" (T) button and select any text you want in your PDF document. The selected texts will be highlighted with the default light-yellow color.

All these functions help you  mark the content easily. To do so, just click the T button again for a drop-down menu to select the tool  you want.
