This article explains what an EPUB file is, how to open it on all your devices, and how to convert it to another format that will work with your e-reader.
How can I open or view EPUB files in Windows without using third-party software?
An EPUB file (short for electronic publication) is an eBook file format. You can download and read EPUB files on your smartphone, tablet, eReader, or computer. This freely available eBook standard supports more hardware eBook readers than any other file format.
EPUB 3.3 is the latest EPUB version that allows files to contain videos, audio, and interactive multimedia elements.
EPUB files can be opened in most e-book readers, including the B&N Nook, Kobo eReader, and Apple's Books app. You can convert books with an EPUB converter to make them usable on the Amazon Kindle, or you can use the Send to Kindle app to email the book to your reader, which will do the conversion for you.
