Epub Translator

Epub Translator is a free online tool that translates complete EPUB books into 20 languages. Instead of copying and pasting text into a generic translator, you upload the whole .epub file, choose a target language, and the service processes every readable chapter as one job. You get back two files: a translated EPUB for normal reading and a bilingual EPUB that shows the original and translation side by side. The tool preserves chapter structure, images, formatting, and reading order, so the result still looks and works like a real book.

The process is straightforward. You drag or select a DRM-free EPUB (up to 25 MB), pick from languages like English, Spanish, Chinese, Japanese, French, or German, and choose between Standard or Fast translation speed. The cost depends on the book's character count and speed, and you can see the credit price before starting. Free credits are provided to get you going, and you can top up with paid credits. Once the translation finishes, you can read the book online in the built-in reader or download both EPUB versions. The original book is available to read immediately after upload, even before translation completes.

This tool is ideal for anyone who wants to read books not available in their language, language learners who benefit from side-by-side comparison, and researchers working with foreign-language source texts. It's also handy for people who simply prefer reading in their favorite ebook app — the downloaded EPUB works on phones, tablets, and desktops. Epub Translator is a practical, no-fuss solution for whole-book translation, saving you the hassle of reassembling chapters from a text translator.
