Document translation FAQ
- How do I translate a whole document?
- Upload your file in the translator above — PDF, DOCX, PPTX, XLSX, or EPUB. The text is extracted automatically and the AI translates all of it, not just the first page. When it finishes, read the translation online or download it as PDF or HTML.
- Can it translate an entire book?
- Yes — books are the core use case. The translator works through your manuscript chapter by chapter, keeping names, terms, and style consistent from the first page to the last. Very large books need a Pro plan, which lifts the caps to 20MB and 100,000 characters per file.
- Does the translation keep my document's formatting?
- You get clean translated text that follows your document's structure — headings, paragraphs, and sections — rather than a pixel-perfect copy of the original design. It's built for reading and understanding the content, and you can download the result as a PDF or HTML file.
- What languages can I translate documents into?
- Over 450 languages and dialects — all the major world languages plus ancient and historical ones like Latin, Ancient Greek, Old English, Coptic, and Aramaic that mainstream document translators don't support.
- Is the document translator free?
- Yes — you can translate documents every day at no cost, and no account is needed to start. Signing in raises your daily allowance, and Pro removes the daily cap entirely while unlocking the largest uploads — up to 20MB and 100,000 characters per document.
- Is my document stored or shared?
- Your document is processed solely to generate your translation. It is never published or shared with anyone, and uploaded files are purged from our servers within 90 days at most.
