Adobe Acrobat is a paid program that comes in two versions Acrobat Standard and Acrobat Pro. If you need to create PDFs or if you want to edit or enhance them by adding things like multimedia elements, form fields, or interactivity, you need Adobe Acrobat. What you can't do with Reader however is create PDFs at least not without signing up for Adobe's online PDF creation services.
In addition to viewing PDFs, Reader also boasts a number of features that let you do things to PDFs including searching them, adding comments, completing form fields, and digitally signing them. This course you're watching covers Acrobat Reader which is the free program available from the software company, Adobe, that anyone can download and use to view PDF or portable document format files. Before we jump into things, I wanted to take a moment to clarify the difference between Acrobat Reader and Adobe Acrobat.
