EPUB is an open eBook format developed by the International Digital Publishing Forum (IDPF), widely supported by many eBook readers and software. It is based on XML and ZIP technologies, offering dynamic formatting, cross-platform compatibility, and rich multimedia support, making it suitable for creating high-quality eBook content. Compared to traditional formats like PDF, EPUB provides better readability, especially on devices with different screen sizes, as it can automatically adjust text layout to fit the screen size. Additionally, EPUB files often include metadata (such as author, title, chapter information, etc.), facilitating management and search. It is widely used in the publishing industry and personal creation, suitable for novels, textbooks, magazines, and various types of eBooks.

FB2 is an eBook format originally developed by Russian developers, widely used in Russia and other Eastern European countries for eBook readers.

Additionally, FB2 files typically do not include digital rights management (DRM) protection, facilitating free distribution and conversion. It is widely used in the publishing industry and personal creation, suitable for novels, textbooks, magazines, and various types of eBooks.
