The FB2 (FictionBook 2.0 File) format is an open XML-based ebook format specifically designed for fictional literature, although it can also accommodate non-fiction. Unlike other ebook formats, FB2 focuses on the structure and content of the book, rather than its appearance. This means that the layout, font, and styling are determined by the e-reader device or software, offering a more uniform reading experience across different platforms.
An EPUB file is a digital ebook saved in the EPUB format, an open XML-based format for digital books and publications. It provides a standard digital publication format for publishers and consumers. EPUB files can be viewed with supporting software programs and hardware devices, such as the Sony Reader and Barnes & Noble Nook.
