About formats

EPUB

EPUB (Electronic Publication) is a free, open e-book standard maintained by the W3C (formerly IDPF). EPUB files are ZIP-based archives containing XHTML content, CSS styling, images, and navigation elements, providing reflowable content that adapts to different screen sizes. EPUB is the most widely supported e-book format and is read by Apple Books, Google Play Books, Kobo, Calibre, and most e-readers except older Kindle devices.

Frequently Asked Questions

Is converting EPUB to DOCX free?
Yes. This EPUB → DOCX converter runs entirely in your browser and is completely free — no account, no credits, no watermark.
Which devices and platforms can I use to convert EPUB to DOCX?
Any modern device with a current web browser: Windows, macOS, Linux, Android, iPhone and iPad. There is nothing to install — the conversion happens locally.
Are my EPUB files uploaded to a server?
No. Files never leave your device. The entire EPUB → DOCX conversion runs locally in your browser, so your data stays private.
Can I convert multiple EPUB files at once?
Yes — batch conversion is supported. Add as many EPUB files as you like and convert them to DOCX in one pass, then download the results together.
What is the maximum file size?
There is no fixed server-side limit because the conversion happens in your browser. Practical limits depend on the available memory and CPU of your device.
Will converting EPUB to DOCX lose quality?
No. DOCX is a lossless format (or used in a lossless mode here), so the original data from your EPUB file is preserved bit-for-bit in the converted result.
Will transparency be preserved when converting EPUB to DOCX?
Yes. Both EPUB and DOCX support alpha-channel transparency, so transparent areas of your file are kept unchanged in the DOCX output.
How will the file size change after converting EPUB to DOCX?
Both formats use comparable compression, so the DOCX output will be similar in size to your EPUB file — typically within 10–20% of each other.
