If you’re bilingual, travelling to another country, or simply want to practice your language skills, you may want to use Signal to send messages in another language. You can change your language settings on the Signal secure messaging app on Android and on newer iPhones. However, if you’re using the desktop app, you can’t change only the Signal app’s language — you’ll need to change the language of your whole computer.

How to change language on Signal using the desktop app

On the desktop version of Signal, the language used in Signal will match that of your computer’s general settings. To change the overall language used in Signal, you’ll have to change your computer’s language settings directly. However, you can still toggle spell check options.

1. In Signal’s desktop application, click on your profile icon in the upper left corner of the screen, then click “Preferences.”

How to change language on Signal using the iPhone app

Your ability to change the language on Signal for iPhone depends on the version of iOS your iPhone uses. If you’re using iOS 12 or earlier, Signal’s language will match your iPhone’s default language settings.
