If you: 1. Use Chrome; 2. Need to read a lot of English literature/PDFs/slides; 3. Are short on time or just want to skim; 4. Wish to have machine translation as a reference while conveniently browsing the original text, then anyone meeting at least two of these criteria should undoubtedly try this extension!

Frequently Asked Questions About ePub Translation
When translating ePub books, preserving the original layout, chapter structure, and formatting is crucial for readability. Immersive Translate's document translation feature is specifically designed to handle ePub files while maintaining their structure. Simply upload your ePub file to the platform, select your target language from over 100 supported options, and choose from 18+ translation engines including ChatGPT, DeepL, or Gemini. The tool processes your ePub book and generates a translated version that retains chapter divisions, paragraph breaks, and text styling. For the best results, I recommend using the bilingual output option, which displays the original text alongside the translation. This side-by-side format is particularly valuable when reading foreign literature or studying language, as you can instantly compare phrases and understand context. The translation typically completes within minutes, depending on the book's length, and you can download the translated ePub file to read on any e-reader device or app.
