Amazon Kindle reader uses a proprietary format (AZW) and cannot read ePub files directly though there are free tools to convert ePub into MOBI (or even PDF) which is a format that your Kindle can read.
Other than hardware devices, you can also read .epub books on your desktop or mobile phone using free e-reader software like Mobipocket, FBReader (for Linux), Aldiko (for Android) or Adobe Digital Editions.
If you are looking to download classic titles in ePub format to read offline, the best place is Google Books (select the “public domain only” option).
Google Books has more than a million public domain (out of copyright) books in the EPUB format that are completely free and they aren’t protected by DRM so you can read these ebook titles on any device / computer without restrictions.

Alternatively, you may use the free Calibre program to convert virtually any document format into ePUB in a batch. Calibre is available for Linux, Windows and Mac OS X. And for editing ePUB files, you should try Sigil - a WYSIWYG editor that also runs on Windows, Linux and Mac and support the.
While you can download ePUB books directly from the Google Books website, Sony offers an excellent desktop application (for Mac and PC) that is nice integrated with Google Books and you don’t have to own the Sony Reader for using that application.
