Some people like the Portable Document Format (PDF)
and some are not great fans. The certainty is that at some point you
will come across one to read. Not a problem because there are some good
PDF readers around. Foxit Reader, Nitro PDF, SumatraPDF to name a few, and that’s assuming you don’t want to use Adobe Reader.
If you want to edit or alter a PDF file, a popular way of doing it is
to convert the document into Microsoft Word format and then do your
editing from there.
