One of the best ways to distribute information over Internet or by email is the use of compressed PDF. This file is often more popular than saving in MS Word format (.doc or .docx) for e-books, marketing reports, and other digital assets such as e-textbooks and magazines.
“When you convert documents, forms, graphics, and web pages to PDF, they look just like they would if printed,” said Adobe. “But unlike printed documents, PDF files can contain clickable links and buttons, form fields, video, and audio — as well as logic to help automate routine business processes.”
PDF files make it easier to access and share information at zero cost. However, users need to use specific apps, before they can open this file type.
There are plenty of good applications, including open-source PDF viewers that are capable of reading PDF files.
