Format Information
HTMLZ
HTMLZ (HTML ZIP) is a compressed ebook format that packages HTML content, stylesheets, and images into a single ZIP archive. It serves as a useful intermediate format for ebook conversion workflows, preserving the full HTML structure and styling of the content. HTMLZ is supported by Calibre and is particularly useful for custom ebook processing pipelines and format migration.
EPUB
EPUB (Electronic Publication) is the most widely supported open ebook format. It uses reflowable content that automatically adapts to different screen sizes, making it ideal for reading on phones, tablets, and e-readers. EPUB supports rich formatting, images, embedded fonts, and interactive content. It is the standard format for most e-readers except Amazon Kindle.
