EPUB to HTML Converter
Processing entirely on your device — large files may take a moment.
HTML keeps headings, links and tables intact and ready to publish on the web or convert onwards to other document formats. If your files are still in EPUB format, this page is the shortcut: EPUB is the universal e-book format: a ZIP package of HTML chapters that reflows to any screen size, used by Apple Books, Kobo and Google Play Books.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

Frequently asked questions
Is this EPUB to HTML converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for EPUB to HTML?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
