BookTranslator

BookTranslator is an AI-powered tool designed to translate entire books, documents, and files into over 180 languages while preserving original formatting, layout, and terminology consistency. It supports a wide range of file formats including EPUB, PDF, DOCX, TXT, SRT, and MOBI, with a maximum file size of 300MB. The tool uses context-aware AI translation to maintain the tone, nuance, and cultural meaning of the original text, going beyond word-by-word translation to produce natural, readable results. Users can download target-language or bilingual versions of their translated content, making it suitable for both personal reading and professional publishing preparation.

The platform is used by over 25,000 readers from universities, publishers, and research communities, including institutions like Tsinghua University, Peking University, and Fudan University. It offers a free tier to start, with exact limits that should be verified on the website. BookTranslator aims to save time and money compared to traditional translation services or manual copying and formatting, and provides a showcase of before-and-after translation examples across various file types to demonstrate its accuracy and layout preservation capabilities.

BookTranslator is positioned as a faster, cheaper, and more accurate alternative to manual translation workflows, handling the entire document at once rather than in small chunks. It is particularly beneficial for authors preparing manuscripts for foreign markets, researchers translating academic papers, and readers accessing foreign language books. The service is entirely online, requiring an internet connection and a web browser to upload files and download results.
