What is Epub Translator
Epub Translator is a web-based service that translates entire EPUB books while preserving their structure, images, and formatting. It allows users to upload a DRM-free EPUB, preview a translated chapter for free, and then obtain a fixed quote for translating the whole book. The service supports 41 target languages and offers both translated and bilingual EPUB downloads.
How to use Epub Translator
- Start with a readable EPUB: Choose a readable, DRM-free EPUB within the displayed size limit (≤ 40.0 MB). The free sample translates the opening of the main text in the background, so you can sign up now or come back later in this browser.
- Read the original beside the translation: Translate the opening of your book for free, no sign-up needed, and read it side by side with the original. Translation runs in the background; you can come back in this browser to see it.
- Confirm a whole-book price, then download: Confirm the fixed price and payment timing before starting. Eligible books can be paid for after translation; others require payment first. Once both EPUBs are ready and paid for, you have 24 hours to download. No subscription or Credit purchase is required.
Features of Epub Translator
- Keep the structure: Translation takes place within the EPUB, preserving its images, styles and table of contents. Check the finished book in your reading app or e-reader.
- Keep the context: A glossary and chapter summaries help keep names and terminology consistent throughout the book.
- One translation, two EPUBs: When the job finishes, download a translation-only EPUB and a paragraph-by-paragraph bilingual EPUB. Both come from the same translation and price, ready to open in any EPUB reader.
- 41 target languages: Choose from 41 target languages, including Simplified Chinese or Traditional Chinese with Taiwan or Hong Kong usage.
- Free excerpt preview: Try the opening for free, up to 3,000 source characters and no more than 10% of the book, without signing up or adding a card.
- Privacy and security: Your EPUB and sample stay private. Unused uploads and free samples are deleted after 24 hours, unpaid translations after 7 days, and downloadable translations after 24 hours. Only the selected text and bounded translation context are sent to the model provider.
Use Cases of Epub Translator
- For a book you want to keep reading: An EPUB workflow is useful when the desired result is another readable book file. It handles the book's reading order, background progress, and downloadable editions together. Full translation also uses terminology and context preparation to support continuity between passages.
- For a sentence or a short passage: A general text translator is convenient when you only need to understand a few lines. Our free excerpt preview serves a similar quick-check purpose, using text extracted directly from your EPUB.
- For language learning: A bilingual EPUB places the original and translation together, making it easier to check a phrase, compare terminology, or study a language.
- For publishing or relying on the text: If you intend to publish or rely on the text for consequential decisions, arrange appropriate human review. The bilingual edition can make comparison easier.

FAQ
How do I translate an EPUB file?
Upload a DRM-free EPUB, choose a target language and try the opening for free. Your whole-book quote tells you whether payment is required before translation. Follow the quoted steps to translate, pay and download both EPUB editions.
Is there a free EPUB book translator available?
Yes. Try the opening for free, up to 3,000 source characters and no more than 10% of the book, without signing up or adding a card. After upload, the whole-book quote shows the fixed price and when payment is due. Only eligible books can be translated before payment.
Can I translate a DRM-protected ebook?
No. The uploader rejects protected EPUB archives, and the service does not remove DRM. Use an unprotected EPUB that you created, obtained from an authorized source, or otherwise have permission to translate. A file ending in .epub is not necessarily readable: encrypted content, damaged archives, and books containing only images cannot be treated as ordinary text chapters.
Will an AI book translation be perfect?
No automated translation can promise perfect meaning, style, or terminology. Dialogue, idioms, poetry, and specialized material deserve particular attention. Use the excerpt to check the reading experience, then review important passages against the original. A bilingual edition can make that comparison easier. If you intend to publish or rely on the text for consequential decisions, arrange appropriate human review.
What happens to the file I preview?
Your EPUB and sample stay private. Unused uploads and free samples are deleted after 24 hours, unpaid translations after 7 days, and downloadable translations after 24 hours. Only the selected text and bounded translation context are sent to the model provider.
Can I read the result on my usual ebook reader?
The downloaded result is an EPUB file, so use an app or device workflow that supports importing EPUB. Reader support and rendering vary, particularly for complex styling and bilingual layouts. Try the downloadable sample with your normal setup first. If your device requires a transfer or conversion service, follow that service's current instructions and check the converted result before deleting your original.
