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.
MOBI
MOBI (Mobipocket) is an ebook format originally developed by Mobipocket and later acquired by Amazon. It was the primary format for older Kindle devices and supports features like bookmarks, annotations, and DRM protection. While largely superseded by AZW3/KF8 on newer Kindles, MOBI remains widely used for compatibility with older Kindle models and third-party reading apps.
