What is a .fb2 file?

FictionBook (FB2) is an XML-based e-book format primarily designed for representing books in a structured and standardized way. Its main goal is to preserve the book's structure, including chapters, sections, verses, and notes, rather than focusing on visual presentation. This allows for greater flexibility in how the book is displayed on different devices and software. FB2 files contain metadata about the book, such as the author, title, ISBN, and publisher, making it easier to organize and manage digital libraries. The format supports embedded images and basic formatting like bold, italics, and headings. Because it's XML-based, FB2 files are easily parsed and processed by software, making them a popular choice for e-book archives and digital libraries. The format is open and well-documented, which has contributed to its widespread adoption in the e-book community. While not as visually rich as some other e-book formats, FB2 excels at preserving the structural integrity of the text, ensuring a consistent reading experience across various platforms.
