Convert DOCX files to EPUB free in your browser — no signup, no install, and the file is never uploaded to a server. EPUB opens almost anywhere, so the result works where DOCX did not.
Add your DOCX file
Drag the DOCX file onto the drop area above, or click it to pick a file from your device. You can add several files at once.
Confirm EPUB as the output
EPUB is already selected as the output format on this page. Only the options this format actually supports show up, such as a page range or sheet selection.
Run the conversion
Press the convert button. Processing happens on your own device, so the time depends on your computer rather than a server queue.
Download the EPUB file
When it finishes, download the EPUB file. Converting multiple files gives you the option to download them together as a ZIP.
Microsoft Word's standard document format, internally a zip archive of XML files. It carries formatting, tables, images, and comments.
The international standard for e-books, with text that reflows automatically to fit any screen size. Nearly every e-reader except Kindle supports it.
Yes. DOCX to EPUB conversion is completely free with no signup, no watermark, and no daily limit on the free plan for ordinary use.
No. The conversion runs entirely inside your browser using WebAssembly, so the DOCX file never leaves your device. That is also why it works without an internet connection once the page has loaded.
It can go either way. Both formats are lossless, so nothing is thrown away — the size difference comes from how each one packs the same data.
The free plan handles files up to 200MB. Because processing happens on your own device, very large files depend on your computer's memory rather than a server quota.
