An average internet user comes across a situation at a regular basis where he needs to download a document from either the internet or one that arrived to his email. It is really a relief if the document that you need is a pdf as it is one of the most secure document type and is not susceptible to virus and is recognized as a the most stable document format around the world.
Stability is one of the most important factors for a document format as the last think you want is to send an important document to someone over the internet and end up hearing that they were unable to open the document because it crashed. Many convert their documents to PDF using word to pdf converter as it never crashes, and on top of which it can be protected with password that offers two levels of security. The Owner password is the master password with complete rights over the document and a user password that allows only limited access to avoid unauthorized misuse.
