Convert pdf files into e-books

All the e-books are notepad files. If you want to create an e-book then type whatever you want to on a notepad pageand copy paste in your mobile phone. Your phone will easily open that file. Similarly copy paste the pdf file on a notepad, it will become an e-book. There are two types of notepads - an old version which displays only black letters. - a new version notepad++ which displays colourfull letters. One of thedrawback is that an e-book don't display images. Also only notepad i.e a file saved as .txt works as an e-book whereas wordpad , word , excell ,etc don't.
