About DeepL

Neural translation for text and files, with a web app, desktop apps and an API that accepts glossaries and formality settings.

DeepL is a neural machine translation service with a web translator, desktop apps for Windows and Mac, browser extensions and a developer API. You can paste text, upload Word, PowerPoint or PDF files and get a translated file back with its formatting kept, or call the API from your own software.

Localization teams use it as a machine translation engine inside a TMS, since most translation management systems have a DeepL connector. Marketers and support teams often use the web app directly for emails, help articles and internal documents.

Two settings matter for business use. Glossaries let you fix how specific terms are translated, and a formality option, available for some languages, switches between formal and informal address. Before you roll it out, check which language pairs you need are covered, whether glossaries work for those pairs, and how the paid plans handle the confidentiality of the text you send.
