About DeepL API
DeepL API gives developers programmatic access to DeepL's neural machine translation engine for building multilingual products, localising content, and automating cross-language workflows, with text and document translation endpoints and custom glossaries for brand and technical terminology. Teams integrate high-quality translation into SaaS apps, internal tooling, and customer support pipelines with a single REST call.
Official client libraries ship for Python, Node.js, .NET, Java, PHP, and Ruby, backed by an OpenAPI specification for any other language. The API handles HTML and XML markup, translates Word, PowerPoint, PDF, and text files, detects source language automatically, and honours formal or informal tone settings across dozens of languages.
Key benefits:
- Best-in-class translation quality from DeepL's transformer-based models
- Custom glossaries locking brand terms and technical jargon across languages
- Document translation preserving formatting in Word, PowerPoint, and PDF
- Markup-aware endpoints safely translating HTML and XML content
- Formality control switching between formal and informal tone per language
- Open-source SDKs across Python, Node.js, .NET, Java, PHP, and Ruby
DeepL is headquartered in Cologne, Germany, founded in 2017, with all translation servers operated inside the European Union. The API is GDPR-compliant and ISO 27001 certified, with input text deleted immediately after translation and no data used to train public models, which is critical for regulated and enterprise use.
Why choose DeepL API over Google Translate API?
The decisive argument is data jurisdiction. Google Translate API is headquartered in US, which means personal data processed through it can be subject to non-EU legal regimes: the US CLOUD Act, FISA 702, or similar laws depending on the provider. After the 2020 Schrems II ruling, EU organisations must carry out a transfer impact assessment for every such data flow.
DeepL API removes that overhead. As a Germany-based provider, it operates natively under GDPR, and data stays inside the EU/EEA by default. For regulated sectors such as health, public administration, and finance, that's not a nice-to-have but a requirement. For everyone else, it's concentration-risk insurance: you avoid depending on a single non-EU jurisdiction that can change the rules without warning.
