PDF files are known for how versatile they can be, as they can pretty much take the place of images, texts, graphics and more, all in one format. The problem with them is that most often than naught, you'll need to use third-party applications to do any form of viewing or editing on this format, and usually, these programs are lacking in features, or are too heavy on system resources.
