An Epub is an ebook file format with the .epub extention, just like a Pdf file comes with .pdf extension. Be not confused, An Epub file is different from a Pdf file. A file with the EPUB file extension, short for electronic publication, is a popular and freely available eBook standard, supporting more hardware eBook readers than any other similar file format.
.epub is the file extension of an XML format for reflowable digital books and publications. Contents in Epub are reflowable, which means that when a sentence reaches the end of the allotted space on the page, it wraps around to the next line. And when there is no more space for lines on the page, the text flows over onto the next page. A reflowable document is a type of electronic document that can adapt its presentation to the output device. HTML is a reflowable format as is the case with any resizable electronic page format. ePUB is a simple reflowable format that allows a single column with inline images, in many ways similar to a stripped-down HTML
