What is Epub?
VoidSoul
EPUB is the abbreviation for electronic publication. It is a file format for publishing books and other types of content in a reflowable fashion. This means that the content can adapt itself to fit the available screen space. An EPUB file can be viewed on a 3.5″ cell phone as well as a 10″ tablet or the 22″ monitor of a desktop computer. If the line width is adjusted, the text reflows to make optimum use of the available screen estate. Images can get scaled to achieve the same effect.
An EPUB publication consists of a single file that has the file extension .epub. Above shown is the official logo for EPUB files, published in June 2010 by IDPF.
