A book translator is a tool that takes a complete e-book and returns the same book in another language, with the book still assembled — chapters in order, table of contents, footnotes and images where the author put them. EPUB Translator is an AI book translator: you give it an EPUB, it gives you back an EPUB. Whether you are a learner reading foreign-language originals or a professional working through foreign-language material, that is the difference between getting a book you can read and getting a pile of translated fragments.

Using advanced AI translation models to provide high-quality translation results. AI models are trained on large amounts of bilingual data and can understand context to provide more accurate and natural translations. Whether it's the beautiful expressions in literary works or the professional terminology in technical documents, EPUB Translator handles them all properly.
This is one of the most important technical advantages of EPUB Translator. Our unique translation engine can completely preserve the structure, styles, diagrams, and layout of the original e-book during the translation process. You don't need to worry about format disruption or content loss after translation. The downloaded e-book can be used directly in various readers while maintaining the same reading experience as the original.
EPUB Translator supports translating e-books into multiple target languages, including Chinese, English, Japanese, Arabic, and more. No matter what your native language is, you can easily translate foreign e-books into a language you understand.
During the translation process, you can view the translation progress in real-time. The system displays the current translation status and estimated remaining time, giving you a clear understanding of the entire translation process.
You can complete translation in just a few simple steps: upload the EPUB file, select the target language, confirm the translation, wait for completion, and download. The entire process requires no complex setup, making it easy for even technologically inexperienced users.
EPUB Translator uses a range of advanced technologies to ensure the best translation service:
The system can automatically identify various text content in EPUB files, including body text, titles, notes, tables, etc. The system adopts appropriate translation strategies for different content types to ensure overall translation quality.
AI models have the ability to understand context, selecting the most appropriate translation based on the context of sentences and paragraphs. This makes translation results more accurate and natural, better conforming to the expression habits of the target language.
EPUB Translator has a built-in powerful EPUB parsing engine that can accurately parse the original book's structure information. After translation, the system places translated content back in the precise positions to ensure complete format integrity.
The system handles large EPUB files, including works of well over a million characters.
EPUB Translator is suitable for various use scenarios, meeting the needs of different users:
For language learners, reading original books in the target language is an excellent way to improve language skills. However, many people are daunted by original books filled with new vocabulary. EPUB Translator can translate foreign original works into your native language, allowing you to appreciate original expressions while understanding difficult passages through translation. This bilingual reading method can effectively improve your foreign language reading ability and vocabulary.
Researchers and scholars often need to read large amounts of foreign academic literature. EPUB Translator can help you quickly translate foreign academic papers, academic works, and research materials, allowing you to conduct literature reviews and material collection more efficiently. You can spend more time on research itself rather than on language barriers.
For professionals who need to stay updated with international cutting-edge technology, EPUB Translator is your powerful assistant. Whether it's technical documents, industry reports, or professional books, you can quickly obtain the information you need while staying internationally competitive.
If you enjoy reading foreign novels, biographies, or history books, EPUB Translator makes it easier for you to enjoy reading. The translated e-books maintain the original book's layout design, making your reading experience more comfortable.
Before using EPUB Translator, please understand the following important information:
EPUB Translator accepts EPUB files and text-based PDFs. A PDF is rebuilt into an e-book before translation — paragraphs, chapter headings and running headers are reconstructed from the page layout — and what you download is an EPUB. Scanned PDFs have no text to translate and are rejected at upload. For Word, TXT or other formats, convert them to EPUB first; EPUB is a widely used standard supported by most readers and conversion tools.
The copyright of translated content completely belongs to the uploader. The platform does not own, claim, or participate in any copyright of translation results. The platform only provides AI translation technology tools and has no relationship with translation results. Please ensure you have the right to use and translate the original book.
Translation is charged per character, once per book — there is no subscription. After you upload a file, the exact price for that book is calculated from its own character count and shown before any payment step. See Pricing.
Translation time depends on file size and content complexity. A medium-sized e-book (approximately 100,000 characters) typically takes 1-5 minutes. You can view the progress at any time during translation.
EPUB Translator focuses on the e-book translation field, and its biggest feature is its ability to completely preserve the original book's format and structure. Other general-purpose translation tools cannot achieve this, often requiring significant layout work after translation. EPUB Translator provides one-stop service—you just upload files and get ready-to-read translated e-books.
We use advanced AI translation models trained on large amounts of high-quality bilingual data to provide accurate and natural translation results. At the same time, our format preservation technology ensures translated e-books maintain the same reading experience as the original.
You can translate as many books as you like, one upload at a time. Each book is priced from its own character count and paid for separately.
The copyright of translated content completely belongs to you, and you can use the translation results for any legal purposes, including personal reading, research, sharing, etc. However, please note that translation results may still be subject to the original book's copyright. Please comply with relevant laws and regulations when using.
Pay online at checkout once you have seen the price for your book — one payment per book, no subscription. If you have a coupon code, you can also redeem it for translation credit.
If translation fails during the process, the system will display error messages and provide retry options. Common failure reasons include: incorrect file format, corrupted file, insufficient account balance, etc. Please troubleshoot the issue according to the prompts and retry.
No — but a text-based PDF works fine. The difference is whether the file contains real text or only pictures of pages: if you can select and copy a sentence in your PDF reader, we can translate it. A scan has no text layer, so we detect that at upload and tell you, rather than charging you for an empty book. For a scan, run it through an OCR tool first.
