What happens when you convert DOCX to EPUB
- The Word document is read by pandoc, the open-source document converter, on our conversion server: headings, paragraphs, lists, tables, links, footnotes and images, and written as an EPUB e-book, with a new chapter at each top-level heading and a table of contents.
- Images inside the DOCX are kept.
- The book title is taken from the DOCX's own title if it has one, otherwise it is called Document.
- This conversion runs on our server: the file is uploaded, converted, and deleted together with the result as soon as the result has been sent back to you. Nothing is kept. Files up to 25 MB are accepted.
How to convert DOCX to EPUB online
- Press "Choose DOCX files" and select one or more files, or drag them onto the box. Files up to 25 MB each can be converted.
- There are no settings to choose: the converter keeps everything the target format can hold.
- Press "Convert to EPUB". The file is uploaded to our conversion server, converted in a few seconds, and deleted together with the result as soon as the result is sent back.
- Save each EPUB with its download button. Our server has already deleted both your DOCX and the EPUB by then.
Why convert DOCX to EPUB?
DOCX files usually come from letters, reports, CVs and most documents shared at work. People convert them to EPUB because EPUB reflows to fit any screen and opens in Apple Books, Google Play Books, Kobo and Send to Kindle.
In short, DOCX is good at what it was made for, and EPUB is the more practical choice when the file has to open, upload or print somewhere else. DOCX opens in Word, Google Docs, Pages and LibreOffice Writer, while EPUB opens in Apple Books, Google Play Books, Kobo and most e-reader apps; a Kindle needs it sent through Send to Kindle.

If something is missing, check whether it depended on a file outside the DOCX; the converter reads the file alone.

About DOCX and EPUB files
What is a DOCX file?
DOCX has been Word's default format since 2007. Like XLSX it is a ZIP archive of XML files, which is how its text can be read without Word.
What is an EPUB file?
An EPUB is a ZIP archive of web pages, one per chapter, plus a file that lists their order. That is why its text can be extracted with ordinary web tools.
DOCX to EPUB not working? Common problems
- "Files up to 25 MB can be converted." Server conversions have a size limit. Compress the images inside the file, or split it, and try again.
- "The conversion took too long and was stopped." Very long or complex files can pass the 90 second limit. Split the file and convert the parts.
- The file will not convert. It may be password protected, damaged, or saved in a newer or unusual version of the format.
Convert DOCX to EPUB from the command line
pandoc does the same on your own computer:
pandoc input.docx -o output.epubConverting on your own computer keeps the file entirely local, which is worth it for very large or very sensitive documents. For everything else, the converter on this page does it without installing anything.
DOCX to EPUB converter FAQ
Will I lose quality converting DOCX to EPUB?
The text and its structure are kept exactly. Layout and styling from the DOCX are not, because pandoc converts the document's structure rather than its look.
Why is the EPUB a different size from the DOCX?
Larger than the DOCX, because EPUB wraps the text in styles and settings inside a compressed package, even when the text is short.
Are my DOCX files uploaded?
Yes, for this conversion. A faithful DOCX to EPUB conversion needs pandoc, the open-source document converter, which cannot run in a browser. The file travels over an encrypted connection, is converted in a private temporary folder, and is deleted together with the EPUB as soon as the result has been sent back to you. We do not keep, read or share it.
Can I convert several DOCX files to EPUB at once?
Yes. Select or drop as many files as you like; they are converted one after another and each gets its own download button.
How do I open an EPUB file?
EPUB opens in Apple Books, Google Play Books, Kobo and most e-reader apps; a Kindle needs it sent through Send to Kindle. EPUB is common for e-books from stores other than Amazon and free e-book libraries.
Is this DOCX to EPUB converter free?
Yes. There is no sign-up and no watermark. Because this conversion uses our server, there is a fair-use limit of 25 MB per file and a number of files per hour, which stops the service being overloaded.
Can I convert DOCX to EPUB on my phone?
Yes. It works in Safari on iPhone and iPad and in Chrome on Android. The conversion happens on our server, so it is as fast on a phone as on a computer; the EPUB is saved to your Downloads folder.
