Convert XHTML to EPUB

Understanding xhtml and epub file formats

XHTML (Extensible Hypertext Markup Language) is a web markup language that combines the flexibility of HTML with the strict syntax rules of XML. It is commonly used for structuring and presenting content on the web, and is also a core component in many eBook formats.

EPUB (Electronic Publication) is a widely adopted eBook file format that supports reflowable content, making it adaptable to various screen sizes and devices. EPUB files are essentially ZIP archives containing XHTML content, images, stylesheets, and metadata, organized according to the EPUB standard.
