Translation Quality Tips

• Scanned PDFs — run OCR first, then translate. Scanned images can't be translated directly.
• Technical documents — AI translation handles everyday language well but may struggle with highly specialized jargon in legal, medical, or engineering documents.
• After translating — always have a native speaker review critical documents like contracts or legal notices.

Can I Translate a Password-Protected PDF?

No — you need to unlock the PDF first, then translate it.
