Document Converter

I need to create a program that allows users to convert any document from one file type to another, for example, convert a word document into an excel spreadsheet, or convert a PDF document into a word document. I want this program to be able to convert Microsoft Word documents into a PDF document and vice versa, " " Microsoft Excel documents into a PDF document and vice versa, " " Microsoft Powerpoint into a PDF document and vice versa, " " Microsoft OneNote into a PDF document and vice versa " " A PDF document into a TIFF and vice versa " " A PDF document into a JPEG and vice versa " " A web page into a PDF document " " A web page into a JPEG " " A web page into a TIFF " " Text file (i.e. Notepad or Wordpad document) into a PDF " " Text file (i.e. Notepad or Wordpad document) into a JPEG " " Text file (i.e. Notepad or Wordpad document) into a TIFF " " Text file (i.e. Notepad or Wordpad document) into a Microsoft Word document " " Text file (i.e. Notepad or Wordpad document) into a Microsoft Excel document " " Text file (i.e. Notepad or Wordpad document) into a Microsoft OneNote document " " Text file (i.e. Notepad or Wordpad document) into a Microsoft Powerpoint document This program needs to have the ability to be downloaded online as well as installed via a CD. I also would like advice on if it is possible to create this type of program for mobile devices such as smart phones and tablets.
