DOCX to EPUB Converter – Convert Word to EPUB Free Online
Most writers work in Microsoft Word. Most eReaders speak EPUB. The problem is that Word documents do not open natively on Kindle, Apple Books, Kobo, or any major eReader platform — and manually reformatting a DOCX into a publish-ready eBook used to mean hours of tedious work. Transfonic's free DOCX to EPUB converter closes that gap instantly. Upload your Word document, convert it to EPUB, and have a clean, reflowable eBook file ready to read or publish in seconds — no software, no Calibre, no account required.
How to Convert Word to EPUB Online Free
Converting a Word document to EPUB with Transfonic takes less than a minute. Drag and drop your DOCX file into the tool or click to browse to where it’s saved on your device. Choose EPUB for the output format and click convert. Download Your EPUB File Instantly and Upload to Any eReader or Publishing Platform. Nothing to install — the whole process is in your browser!
For all your other document format needs, Transfonic's document conversion tool handles PDF, TXT, HTML, Markdown, RTF, and more in one place.
What Happens to Your Formatting
Headings, paragraphs, bold, italic, and basic list formatting all carry over cleanly from DOCX to EPUB. Chapter structure is preserved when your Word document uses proper heading styles — H1 for chapter titles, H2 for subheadings. Transfonic produces EPUB 3.0-compliant files compatible with Kindle, Apple Books, Kobo, and Google Play Books. In testing, a 20-page 1.8MB DOCX converted to a 380KB EPUB in under 4 seconds, with chapter navigation working correctly on mobile and eReader. Complex layouts, custom fonts, or heavily styled elements may need minor cleanup — this is standard across all Word to EPUB converters. For PDF-based workflows, Transfonic's free PDF to EPUB converter is a useful companion tool.
