# Translate

> Translate text strings and complete documents with the DeepL API. Find quickstarts, markup handling guides, and customization options.

The Translate API converts text between any of the [supported languages](/docs/getting-started/supported-languages) through two endpoints:

* **Text translation** (`/v2/translate`): translate one or many strings per request, with automatic source language detection. Suited for UI strings, messages, and any text your application handles directly.
* **Document translation** (`/v2/document`): upload complete files, including Word, PowerPoint, PDF, and HTML, and download the translation with the original formatting intact.

## Customize translations

Beyond per-request parameters, DeepL's customization features let you tailor translations to your domain and keep terminology consistent: glossaries, style rules, custom instructions, and translation memories. They all work with both text and document translation; see the [Customize tab](/docs/customize/overview) for guides on each.
