Word to EPUB Converter

EPUB (Electronic Publication) is the universal ebook format supported by Apple Books, Google Play Books, Kobo, and virtually every e-reader except Amazon Kindle (which uses its own format but can import EPUB). Converting Word to EPUB transforms your manuscript or document into a reflowable ebook that adapts to any screen size — from phones to tablets to dedicated e-readers. SublimePDF maps Word headings to EPUB chapters, embeds images, generates a navigable table of contents, and applies clean semantic HTML that e-readers render beautifully.

How to Convert Word to EPUB Online

Upload your Word document

Set the ebook title, author name, language, publisher, and optional cover image. These metadata fields appear in e-reader libraries and bookstores. Add a description and keywords for discoverability.

Word to EPUB Conversion FAQ

Which e-readers support EPUB?

EPUB is supported by Apple Books, Google Play Books, Kobo, Nook, and most third-party reading apps. Amazon Kindle does not natively support EPUB but can import it through Kindle's Send to Kindle service or via Calibre conversion.

How should I structure my Word document for the best EPUB output?

Use Heading 1 for chapter titles, Heading 2 for sections, and Heading 3 for subsections. This heading hierarchy is directly mapped to the EPUB's chapter structure and table of contents. Avoid manual formatting — use Word styles consistently.

Will images in my Word document appear in the EPUB?

Yes. Embedded images are included and can be automatically resized for optimal ebook display (typically max 1000px wide to balance quality and file size). Image captions are preserved.

Can I add a cover image to the EPUB?

Yes. Upload a cover image during the metadata configuration step. For best results, use a high-resolution image (at least 1600×2400 pixels) in JPG or PNG format.

Will the EPUB pass validation for bookstore submission?

Yes. The output is validated against EPUB 3 specifications as required by Apple Books, Google Play Books, Kobo, and other distribution platforms. The converter produces clean, standards-compliant markup.
