Three pictures for the three things people want to know before handing over a book: what happens to the file, what the bilingual output looks like, and which languages a book can go into.
EPUB Translator is an online book translator: hand it an e-book and it gives you the same book in another language. Not a page, not a selection — the whole file: every chapter, in reading order, still openable in Apple Books, Kobo, Calibre, or any other reader that handles EPUB.
The input format is EPUB, which is what most e-books already are and what every reader app opens. Everything below describes what a book translator has to get right that a general-purpose translator does not.
Most ways of translating a book fall down at the file. Browser extensions translate what is on screen and leave you with nothing to keep. Copying chapters into a chat model works until you hit the context limit, and then you are stitching thirty pieces back together by hand. Generic document converters flatten an EPUB into something that is no longer an e-book. This tool exists because the format is the hard part, not the sentences.
Pick an EPUB from your device. Nothing is uploaded until you say so, and you do not need an account to get this far — the file is read in your own browser just far enough to recognise the book, so its title and cover come straight back at you. If what you have is a Kindle file instead, the free Kindle to EPUB converter turns a DRM-free AZW3 or MOBI into an EPUB first — also in your own browser, with nothing uploaded anywhere.
Pick one of the sixteen target languages. The source language is detected automatically; you never have to declare that the book is in German.
Sign in and the exact price for this file is on screen before you pay anything. It is one payment for this book — no subscription, nothing to cancel — and the EPUB you download keeps the chapters, layout and images of the original.
Sixteen target languages: English, Simplified Chinese, Traditional Chinese, Japanese, French, Spanish, Arabic, Korean, Vietnamese, Indonesian, Polish, Czech, Italian, German, Portuguese, and Turkish. Source language is auto-detected and is not restricted to that list — a Swedish novel into English works fine. The full breakdown is on Supported Languages.
You pay per book, once, with no subscription and nothing to cancel. The exact figure depends on how long the book is, and you see it before you commit, ahead of any payment step. Current rates are on the book translation pricing page.
PDF is not supported. A PDF has no chapter structure to preserve, so producing a readable translated e-book from one is a different problem, and shipping a bad version of it would waste your money. If you need it, say so on the upload screen and it feeds directly into what gets built next. DRM-protected files cannot be opened at all — that is a property of the file, not a limitation we chose.
A book translator takes a complete e-book and hands it back in another language with the book still assembled: chapters in order, table of contents, footnotes, and images where the author put them. That is what separates it from a page translator or a chat model — those work on fragments and leave the reassembly to you.
Yes. The translation is applied to the text inside the EPUB's existing structure, so chapters, the table of contents, footnotes, and inline styling come back intact. That is the entire reason this is a dedicated tool and not a generic document converter. See how EPUB Translator works.
Most books finish in minutes rather than hours. Length is what drives it — a short novel is quick, a 700-page technical manual takes longer. You can close the tab; the job keeps running and the file is waiting when you come back.
Yes. After signing in, the exact price for your file is shown before any payment — worked out from the book's own character count, not from a guess at its page count. You pay once for that file, with no subscription attached.
You can, and for one chapter it is fine. Across a whole book you hit context limits, lose the chapter structure, and end up reassembling an EPUB by hand with no consistency of terminology between the pieces. The trade-offs are laid out in EPUB Translator vs. a raw LLM.
It is processed to produce your translation and it stays yours. Upload only books you actually own the right to read — the tool is for reading foreign material you have legitimate access to, not for redistributing someone's catalogue.
Any reader that opens EPUB: Apple Books, Kobo, Calibre, Thorium, Google Play Books. The output is a standard EPUB file you download and own, not a document locked inside this site. What people actually do with it is collected in use cases.
