Convert DOCX to EPUB — Free Online Converter

DOCX structures content as pages with fixed margins, headers, footers, and precise typographic control. EPUB (Electronic Publication) is the open standard for reflowable e-books, used by Apple Books, Kobo, Google Play Books, and virtually every e-reader except Amazon's Kindle (which uses its own format but accepts EPUB for conversion). Converting DOCX to EPUB transforms a page-oriented document into a reflowable reading experience optimized for screens of all sizes.

The conversion remaps DOCX's page model to EPUB's chapter-based structure. Heading styles become chapter breaks and navigation points. Body text becomes reflowable paragraphs that adapt to any screen width. Images are resized for e-reader displays. The output is an EPUB 3 file — a ZIP archive containing XHTML content, a navigation document (NCX/TOC), CSS styles, and embedded media — ready for distribution through any e-book platform.

Self-publishing authors typically write in Word and need EPUB for distribution on Apple Books, Kobo, Barnes & Noble, Google Play Books, and Smashwords. These platforms require EPUB submissions — not DOCX. Converting your manuscript from DOCX to EPUB is the standard path from writing to publishing for the majority of the e-book market.

EPUB is also the preferred format for organizational document distribution on mobile devices. Corporate training manuals, employee handbooks, and policy documents are more pleasant to read as reflowable e-books than as fixed-layout DOCX files. EPUB supports adjustable font sizes, night mode, and offline reading — features that improve reading accessibility on phones and tablets.
