AI PDF Translation: Translate Documents to Any Language
Key Points
- AI translates entire PDF documents while preserving the structure and meaning
- Supports translation between major world languages with context-aware accuracy
- Text extraction happens client-side; only text is sent to the AI for translation
Reading documents in a foreign language can be challenging and time-consuming. AI-powered PDF translation converts your document's content into your preferred language while maintaining context and meaning. Unlike word-by-word translation, AI understands context, idioms, and technical terminology for more natural results.

Common Use Cases
International Business Documents
Translate contracts, proposals, and correspondence from foreign partners to understand terms and conditions before engaging legal review.
Academic Research in Other Languages
Access research papers published in other languages—translate Japanese, German, or Chinese studies to expand your literature review.
Government & Legal Forms
Understand foreign government documents, visa applications, or legal notices by translating them into your native language.
Product Manuals & Technical Docs
Translate product manuals, datasheets, or technical specifications from manufacturers in other countries.
Translation Tips
AI translation works best with well-formatted text—scanned PDFs with selectable text produce better results than image-based PDFs.
For legal or medical documents, use AI translation as a first pass and have a professional translator verify critical sections.
Technical terminology may vary by region—review translated technical terms for your specific industry context.
Shorter documents (under 50 pages) tend to produce more consistent translations than very long documents.
PDF text is extracted in your browser and sent to the AI API for translation. The original file is not uploaded. AI translations are for informational purposes—professional human translation is recommended for legal, medical, or official documents.
