PDF file format has always been in demand since its creation in 90’s by Adobe. According to a search accomplished by Google, it is proven that today, there are more than 700 million PDF documents being used over the internet. There are many reasons why the PDF file format is in demand. The first and foremost reason is of course the security of the document.

This is because the PDF files are read only files and therefore they cannot be edited unless and until the user of the file is permitted to do so. PDF files are mostly used to drawings, presentations, legal documents, invoices etc. Also PDF files are compact and less heavy as compared to other files. PDF files are very much compatible with all the devices be it a computer or a mobile phone. All you need is the Acrobat Reader to view them.
