Translate - Document task

The Translate - Document task lets you translate a single document file in real-time (synchronously) using Cloud Translation. You can directly translate formatted documents such as PDF and DOCX while preserving their original formatting and layout. For information about the supported file formats for document translation, see Supported file formats.

Cloud Translation is a Google Cloud service that allows you to translate text for more than 100 language pairs with the capability of auto language detection. For a list of all supported languages, see Supported languages.
