Translate text instantly or in batches across more than 100 languages, powered by the latest innovations in machine translation. Support a wide range of use cases, such as translation for call centres, multilingual conversational agents or in-app communication.

Broad language coverage

Accurately translate text among more than 100 languages.

Customisable translations

Build custom models to handle domain-specific terminology.


Access the same technology that powers billions of translations every day across Microsoft products.

Built-in security

Your data remains yours – your text input isn’t logged during translation.

Extend your application’s reach

Take advantage of our translation as a service with a single REST API call to remove the complexity of building instant translation into your apps and solutions. Accurately detect the language of your source text, look up alternative translations with the bilingual dictionary or convert text from one script to another. Use your preferred programming language, including Python, C#, Java, JavaScript and Go.

Customise your translations

Customise your text translations to reflect domain-specific terminology. Define how those terms are translated based on previously translated documents. Build customised translation models without machine learning expertise.

Benefit from a tested, scalable translation engine

Build your solutions using a production-ready translation engine that has been tested at scale, powering translations across Microsoft products such as Word, PowerPoint, Teams, Edge, Visual Studio and Bing. Seamlessly scale up or down based on your translation needs.

Comprehensive privacy and security

  • Translator, part of Azure Cognitive Services, is certified by SOC, FedRAMP, HIPAA, HITRUST and ISO.
  • Customer data isn’t written to persistent storage. View and delete your custom data and models at any time.
  • Microsoft doesn’t share the custom training performed on your training material or use it to improve Translator quality.

Get the power, control and customisation you need with flexible pricing

  • Only pay for what you use, with no upfront costs.
