Adobe Reader is the essential PDF viewer.
Adobe Reader is a software that is designed to view documents in PDF format safely. PDF (Portable Document Format) has one significant advantage of allowing cross-platform compatibility. An individual can view a PDF file on a Windows computer, or Linux, or even on a mobile device. Adobe Systems created PDF format in 1993, however, since it was difficult to make it accepted at the start Adobe resolved to begin releasing the software free of charge to stay ahead of the pack from formats like Envoy, Common Ground Digital Paper. Today, PDF is the most common format for printable documents, and it is extensively used for e-books publishing. PDF has gone through a lot of updates and changes which correspond to the number of Adobe Reader versions.
