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.
