Download an original and translated example
A short gardening ebook: English to Spanish
Open a three-chapter example with a linked contents list, an illustration and styled chapter text. Polytranslator created this synthetic source and translated it with Fast, Keep formatting on September 16, 2026. The downloaded output is unedited.
This example retains its three chapters, working contents links, illustration and styles; the illustration's alternative text remains in English. It demonstrates one short reflowable ebook, with line breaks and page counts that depend on your reader and font settings.
How to translate your file
1
Upload your EPUB book
Use an unprotected EPUB that you have permission to translate. Keep the original ebook package so its chapters, navigation and images remain available to the translator.
2
Choose the target language
Select English, Spanish, Arabic or another target language, then start the translation. The uploader checks the file first.
3
Open the translated book in your reader
Download the EPUB and open it in your ebook app. Use the contents list to jump between chapters, adjust the reading font, and compare passages with the original.
Keep chapters and navigation in a translated ebook
The EPUB workflow writes translated text back into the book's content files. Chapters stay in reading order, headings and paragraphs remain text, and the ebook keeps its links, styles and packaged images. You can continue reading it as an EPUB instead of copying a long translation into a separate document.
The translator also handles supported table-of-contents and navigation labels and updates the book's language metadata. Chapter titles in the reader's contents panel deserve a check alongside the visible chapter headings, especially in older or unusually structured ebooks.
Footnote links and inline emphasis remain part of the source structure. Text inside a picture follows the image workflow and remains image content; it does not become an editable paragraph.
EPUB formatting adapts to the reader
Most EPUB books are reflowable: their line breaks and page count depend on the screen, font size and reader settings. A translated sentence can be longer or shorter than its source, so keeping the book's structure does not mean keeping the same pagination.
Review the beginning, middle and end of a long book. Try its chapter links, footnote links and illustrated pages in the app you plan to use. For Arabic or another right-to-left target, check text direction and passages that mix names, numbers or other scripts.
A book can repeat a name or specialized term across many chapters. Compare those recurring terms before sharing the translation; an AI-generated book is a draft for reading and review, rather than a guarantee of consistent editorial choices throughout.
Translate an EPUB to English, Spanish or another language
Choose English to read an ebook from another language, or choose a different target to prepare a reading copy for your audience. The same uploader handles either direction. The selected target language determines the language of the downloaded EPUB.
Use EPUB when you have the original ebook and want adjustable text and chapter navigation. For a book available only as a PDF or scanned pages, use the PDF translator instead: changing a filename to .epub does not turn fixed pages into a structured ebook.
EPUB Translator: common questions
Can I download the translated book as an EPUB?
Yes. Upload an EPUB to receive a translated EPUB with its ebook structure retained.
Can I translate a whole ebook?
You can submit an EPUB as one file. File size and extracted-text limits determine whether the book can be processed, and the uploader checks the file before translation; not every full-length book will fit the limits.
Does EPUB translation preserve the table of contents?
The EPUB keeps its chapter structure and navigation links, and supported navigation labels are translated. Check the contents panel and chapter links in your reader after downloading, particularly for older or unusually structured books.
Can I translate a protected Kindle book or remove DRM?
This page is for unprotected EPUB files. It does not remove DRM or unlock protected ebooks. Use an EPUB you are authorized to translate; a Kindle purchase does not necessarily include an unprotected EPUB file.
Is the EPUB translator free?
You can try it free, with no account needed, and signing in gives you a larger daily allowance. Pro and Scholar are there for longer documents and regular use.

A 1747 parish baptism register in Latin. Ruled columns, godparents and marginal notes stay aligned, so the genealogy still reads as a register.
