Frequently Asked Questions
DOCX is the default document format for Microsoft Word since 2007, based on the Office Open XML standard. It stores text, formatting, images, tables, and macros in a compressed XML-based package.
HTMLZ (HTMLZ eBook) is an ebook format designed for reading long-form text on dedicated e-readers, tablets, and ebook apps. It is part of the ebooks family and typically supports reflowable text, embedded images, chapter navigation, cover art, and metadata (title, author, ISBN) in a portable package.
DOCX files open in Microsoft Word, Google Docs (free), LibreOffice Writer (free), and Apple Pages. You can also view them in web browsers using OneDrive or Google Drive.
Dedicated e-readers — Kindle, Kobo, Nook, Pocketbook — support the most common ebook formats. On phones, Apple Books, Google Play Books, Moon+ Reader and KOReader all handle HTMLZ. For desktop reading, Calibre is the universal ebook viewer and library manager. Convert to EPUB or PDF for maximum compatibility.
Use DOCX when the document will be edited by others or needs collaborative review. Use PDF when you want to lock the layout and ensure the document looks identical on every device and printer.
Upload your HTMLZ to KaijuConverter and pick EPUB, MOBI, PDF, AZW3, or similar targets. Our Calibre-powered pipeline preserves chapter structure, embedded images, cover art, and metadata. Conversion takes seconds for typical novels; long technical books with many images may take a little longer.
