Frequently Asked Questions
How accurate is DeepL compared to Google Translate?
DeepL is widely recognized for superior translation accuracy, especially for European languages. Independent evaluations show DeepL consistently produces more natural-sounding, contextually-aware translations than Google Translate. However, for non-European and less common language pairs, the difference narrows.
Is DeepL secure for sensitive business documents?
Yes. DeepL Pro and API Pro customers have world-leading data protection: texts are deleted immediately after translation, not stored for training. DeepL maintains ISO 27001, SOC 2 Type II, HIPAA, and GDPR compliance. Enterprise customers can use Bring Your Own Key encryption for maximum control.
How many languages does DeepL support?
DeepL supports 100+ languages for translation, including all major European, Asian, and world languages. However, it supports fewer languages overall compared to Google Translate's 130+. Support is strongest for European language pairs.
What is the cost of using DeepL API for production applications?
DeepL API Pro costs $5.49/month base fee plus $25 per 1,000,000 characters translated. Document translation has a 50,000 character minimum charge per file. Free tier allows 500,000 characters monthly. For high-volume usage, enterprise custom pricing is available.
Can I customize DeepL translations for my brand terminology?
Yes, through glossary management. You can create glossaries with custom terminology pairs (up to 2,000 glossaries with 5,000 term pairs each in Ultimate plans) and apply style rules for formal/informal tone. However, DeepL doesn't support training on custom datasets like some competitors.
Does DeepL work offline?
No, DeepL requires an active internet connection. The service is cloud-based and does not offer offline functionality. However, translations can be cached locally in applications for quick access.
What platforms does DeepL support?
DeepL is available on Web (deepl.com), Windows desktop, macOS, iOS, Android, as a Chrome browser extension, and via REST API. It integrates with Microsoft Teams, Word, CAT tools like SDL Trados, and 1,000+ third-party apps through automation platforms.
