EPUB Translator

EPUB Translator is an online AI tool that translates entire, DRM-free EPUB books into 41 target languages. Upload an .epub file to preview a translated opening chapter in your chosen language, then generate a complete translated EPUB you can read in your usual EPUB reader.

The translation is applied within the EPUB structure—so images, styles, chapter order, and the table of contents are preserved. Instead of flattening your book into a single text response, it aims to retain reading navigation and supported inline formatting while replacing the readable text. To help keep wording consistent across the book, it supports a book-wide glossary and chapter summaries.

After translation finishes, you can download two versions: a translation-only EPUB for continuous reading and a bilingual EPUB that places the original alongside a paragraph-by-paragraph translation for comparison and language study. Both downloads come from the same completed translation, and you can open the sample/bilingual views in your EPUB reader to judge how complex layout and highly styled pages appear on your device.

Who it’s for: readers who want an actually readable EPUB in another language, language learners who prefer side-by-side context, and anyone translating book-length chapter sequences without losing navigation or formatting. You can try the first chapter free without sign-up. Files are stored privately for 24 hours, and whole-book translations are pay-per-book with a fixed whole-book price confirmed before payment and download.

What file type can I translate with EPUB Translator?

You translate EPUB files (.epub) up to the displayed size limit (≤ 40.0 MB). The tool does not translate PDFs or perform OCR.

Does EPUB Translator preserve the book’s layout and table of contents?

Yes. Translation runs within the EPUB so it preserves images, styles, chapter structure, and the table of contents, with translated headings and navigation intended to remain usable.

Can I preview a translation before translating the whole book?

Yes. You can try the opening chapter for free without sign-up and read the preview side by side with the original in your browser.

What downloads do I get after a whole-book translation?

You can download (1) a translated EPUB for continuous reading and (2) a bilingual EPUB that shows original and paragraph-by-paragraph translation together.

How does pay-per-book pricing and downloading work?

Whole-book translation is pay-per-book with no subscription. A fixed whole-book price is confirmed before payment, and once both EPUBs are ready after payment, you have 24 hours to download.

Will I be able to read the result in my usual EPUB reader?

Yes. The output is an EPUB designed to open in standard EPUB reader apps. Line breaks and page appearance may differ by reader, so check the translated opening sample in your app before committing to a large book.
