Best File Formats for Book Translation: EPUB vs DOCX vs PDF

Which Format Should You Use?

When uploading your book for translation, the file format matters more than you might think.

EPUB — Best for E-books

EPUB preserves chapter structure, formatting, and metadata. Our system extracts text while maintaining chapter boundaries.

DOCX — Best for Manuscripts

Microsoft Word documents are the most common format for book manuscripts. They preserve paragraph structure and basic formatting.

PDF — Use with Caution

PDFs are great for preserving layout, but text extraction can be imperfect—especially for scanned documents. If you have the original manuscript in DOCX or EPUB, use that instead.

TXT — Simplest Option

Plain text files are the most reliable format. No formatting to worry about, and our AI handles paragraph detection automatically.

Pro tip: Always keep your original file. Our translation preserves your source material untouched.
