# Localization support in Typescript PDF Viewer

The PDF Viewer fully supports localization, allowing all UI text, tooltips, and messages to be replaced with culture-specific strings so the interface matches users’ language and regional settings.

## Localization keys reference

The PDF Viewer supports localization using culture-specific string collections. By default, the component uses the "en-US" culture.

The following table lists the default text values used by the PDF Viewer in the "en-US" culture:

## Default language (en-US)

By default, the PDF Viewer uses the en-US culture and requires no additional configuration.
