How to Convert Word to EPUB

You have finished writing something long in Word and you want to read it on a Kindle, a Kobo, an iPad or a phone. The instinct is to export a PDF. On an e-reader, a PDF is almost always the wrong answer.

Why not just send a PDF?

A PDF is a fixed page. Every line break, every margin, every font size was decided when the file was made, and the reader has to accept them. On a six-inch screen that means pinching, panning, and text too small to read comfortably.

EPUB is reflowable. The text has no fixed page; it flows to fit whatever screen it lands on. Which gives the reader — you — control:

• change the font size and the typeface without breaking the layout
• read in portrait or landscape, on any screen size, with no zooming
• night mode, adjustable margins and line spacing
• working search, bookmarks, highlights and a tappable table of contents
• your position syncs across devices, because “where you are” is a position in the text rather than a page number
• screen readers handle it properly, because it is structured text underneath

Under the surface an EPUB is a zip archive of HTML and CSS — an ebook is essentially a small offline website, which is exactly why it adapts so well.

Convert Word to EPUB, step by step

1. Tidy the document first (see the next section — this is what decides whether your ebook is good or merely functional).
2. Open the converter. Go to Word to EPUB. It accepts .docx, legacy .doc and OpenDocument .odt.
3. Convert. LibreOffice on our server exports the document as EPUB.
4. Download and test it on an actual reader before you share it with anyone.

Prepare the document — this is the whole game

A converter can only work with the structure you gave it. Ten minutes in Word beforehand is worth more than any amount of fiddling afterwards.

• Use real heading styles.Chapter titles must be Heading 1, not 16pt bold text you centred by hand. This is how the table of contents gets built and how navigation works. If you do one thing on this list, do this one.
• Use Word’s page break for chapter breaks, not a stack of empty paragraphs. Blank lines become blank lines in a reflowing book, in random places.
• Never indent with spaces or tabs. Set first-line indent in the paragraph style instead. Manual spacing looks chaotic once text reflows.
• Forget page numbers, headers and footers. There are no pages in an EPUB, so these are dropped — as they should be.
• Keep images inline and reasonably sized. Floating images with text wrapping have nowhere to float to on a narrow screen.
• Fill in the document properties.Title and author in Word’s File → Info become the ebook’s metadata, which is what your reader’s library displays. An ebook called final-draft-v7-REALis nobody’s friend.
• Simplify the fancy bits. Text boxes, multi-column layouts, SmartArt and elaborate tables do not survive reflow well. Convert them to plain paragraphs or images first.

What to check in the converted file

Open it on a real device or in a reader app and look for four things:

1. The table of contents. Every chapter listed, in order, and each entry jumps to the right place. If it is empty, your headings were not real styles — go back and fix that.
2. Chapter starts. Each should begin on a fresh screen, not halfway down the previous one.
3. Images. Present, right way up, and not so large that they overflow a small screen.
4. Reflow behaviour. Change the font size to the largest setting. Text should stay tidy; anything that falls apart was holding itself together with manual spacing.

What about a cover, and about Kindle?

LibreOffice’s EPUB export does not build a designed cover for you. If you want one, put a full-page image as the very first thing in the document and it will lead the book — or add a proper cover afterwards in a dedicated ebook editor such as Sigil or Calibre, both free.

For Kindle: Amazon accepts EPUB directly, both for personal Send-to-Kindle and for publishing through KDP, and converts to its own format at their end. You do not need to produce a MOBI, and you should not try — that format is retired.

And if you are self-publishing commercially, treat this conversion as a solid first draft of the ebook rather than the finished product. A store-ready book usually gets a pass through a dedicated ebook editor for cover, metadata, and validation. This gets you 90% of the way in ten seconds.

When a different format is the right call

• The layout is the content — a form, an invoice, a design-heavy brochure, sheet music, anything with a fixed grid? Use Word to PDF. Reflowing would destroy it.
• Publishing on the web? Word to HTML gives you the same structure as markup you can drop into a site.
• Only need the raw words? Word to Text.

Is it private and free?

Building an EPUB from a word processor document needs a real office engine, so this converter runs on our secure server rather than in your browser. Your manuscript is uploaded over an encrypted HTTPS connection, converted in an isolated workspace, and deleted automatically the moment the EPUB is sent back— nothing stored, logged or shared. Free: no watermark, no sign-up, no daily limit, files up to 100 MB.

For an unpublished manuscript you are anxious about, a desktop tool that never leaves your machine is the more cautious choice — sensible advice for any online service, ours included.

Frequently asked questions

My table of contents is empty.The chapter titles were manually formatted rather than styled. Apply Heading 1 to each in Word and convert again — this fixes it every time.

Can I read the EPUB on an iPhone or Android? Yes. Apple Books opens EPUB natively; on Android, Google Play Books, Moon+ Reader and others do. On a computer, Calibre or a browser extension will do.

Will my fonts be preserved? Not usually, and that is fine — e-readers deliberately let the reader choose the typeface. Do not design around a specific font.

Do footnotes work? They convert as linked notes. Check a couple, as their placement varies by reader app.

Can I sell the result on Amazon or Apple Books? Technically yes, both accept EPUB. Run it through an EPUB validator and add a proper cover first — stores reject books on metadata and cover problems far more often than on content.

Does it work on a .doc or .odt? Yes, both are accepted alongside .docx.
