What is a .fb2 file?

FictionBook (FB2) is an XML-based e-book format. It's designed to represent all elements of a book, including the title page, chapters, poems, and illustrations, in a structured way. The primary goal of the FB2 format is to preserve the book's structure and metadata, making it suitable for long-term storage and conversion to other formats. Unlike formats that focus on visual layout (like PDF), FB2 emphasizes content and semantic markup. This allows for better reflowing of text on different devices and screen sizes. The format supports metadata such as author, title, ISBN, and publisher, which are stored within the XML structure. FB2 files are typically compressed using ZIP to reduce file size, resulting in the .fb2.zip extension. The format is popular among e-book enthusiasts and is widely supported by e-readers and e-book management software. Its open nature and focus on content preservation make it a valuable format for digital libraries and archiving.
