Book Translator

Book Translator is an AI-powered translation tool designed specifically for long-form content such as books, scripts, and documents. It enables users to translate entire files quickly and accurately into a wide range of target languages, while preserving structure and formatting. The platform supports both individual authors and professional teams who need reliable, large-scale translation without manual copy-paste work or fragmented workflows.

Book Translator supports multiple file formats, including EPUB, PDF, TXT, DOCX, SRT, VTT, ASS, SSA, and MD, making it suitable for both written books and subtitle-based content. The tool is optimized for full-document translation, handling entire books in a single operation rather than chapter by chapter. It aims to maintain paragraph structure, chapters, subtitles, and styling where possible, reducing the need for post-editing. The service is fully online via booktranslator.app, so users can upload files, select the target language, and receive translated output in minutes.
