How to Change the Language on Facebook (Any Device)
Facebook defaults to the language tied to your region or browser settings when you first sign up — but that's not always the language you want to read and write in. Whether you've moved to a new country, prefer to browse in your native tongue, or accidentally switched to an unfamiliar language and can't find your way back, changing Facebook's display language is a built-in feature available on every platform.
Here's exactly how it works across devices, plus what to expect when you make the switch.
What "Language" Actually Controls on Facebook
Before diving into steps, it's worth knowing what you're changing. Facebook's display language affects the interface — menus, buttons, notifications, and prompts. It does not automatically translate posts from friends or pages you follow. That's handled separately through Facebook's translation feature, which appears on individual posts.
So if you change your language to French, your friend's English posts will still appear in English unless you tap "See Translation."
How to Change the Language on Facebook — Desktop (Web Browser)
The most reliable place to change your Facebook language is through a desktop browser, because you get access to the full Settings menu.
- Log into Facebook and click your profile picture or the downward arrow (▼) in the top-right corner
- Select Settings & Privacy, then click Settings
- In the left-hand menu, find and click Language and Region
- Under Facebook language, click Edit
- Use the dropdown to select your preferred language
- Click Save Changes
The page will reload in your chosen language immediately. No log-out required.
💡 Tip: If you're already in a language you don't understand and you need to navigate back — the Settings icon is typically a downward-pointing arrow or gear icon at the top right. "Settings & Privacy" is usually the second or third option in that dropdown.
How to Change the Language on Facebook — iPhone (iOS App)
The Facebook iOS app doesn't have a language setting built directly into the app itself. Instead, it follows your iPhone's system language.
To change it:
- Open your iPhone's Settings
- Scroll down and tap Facebook
- Tap Language (if available) or go to Settings → General → Language & Region and adjust your iPhone's preferred language
Alternatively, some regions and app versions do surface a language option inside the app under:
Menu (☰) → Settings & Privacy → Settings → Language
If that path doesn't appear, the system language route is the reliable fallback.
How to Change the Language on Facebook — Android App
The Android Facebook app typically includes a language setting within the app itself:
- Tap the three horizontal lines (☰) in the top-right corner to open the menu
- Scroll down and tap Settings & Privacy
- Tap Settings
- Scroll to the Media and Contacts or General section and look for Language
- Select your preferred language from the list
- The app will refresh in the new language
If you don't see this option, your version of the app may defer to Android's system language. You can change that under Android Settings → General Management → Language.
Platform Differences at a Glance
| Platform | Language Setting Location | Notes |
|---|---|---|
| Desktop (Web) | Settings → Language and Region | Most reliable, full control |
| iOS App | Device Settings → Facebook, or via system language | App may follow iOS system language |
| Android App | App Menu → Settings & Privacy → Language | Some versions defer to Android system |
| Mobile Browser | Follows the same logic as desktop | Use full site mode for best access |
What Changes — and What Doesn't
When you switch Facebook's display language:
- ✅ All menus, buttons, and labels update immediately
- ✅ Notifications and system messages from Facebook update
- ✅ Help Center content may switch to the selected language
- ❌ User-generated posts do not auto-translate (use the "See Translation" link on individual posts)
- ❌ Ads may or may not reflect the new language depending on targeting
- ❌ Your profile information (bio, work history, etc.) stays in whatever language you typed it in
When the Language Reverts or Doesn't Stick
Some users find their language preference resets after a while. This usually happens because:
- Browser language settings are overriding Facebook's stored preference — Facebook sometimes defers to your browser's
Accept-Languageheader - You're using multiple devices and one device hasn't synced the change
- The app was updated, which can occasionally reset preferences on certain Android builds
- You're in a region where Facebook defaults aggressively to the local language
The fix is usually to set the language again via desktop settings, then also update your browser's language preference to match — both Chrome and Firefox let you set a preferred display language under their settings.
The Variable That Changes Everything
Knowing the steps is only part of the picture. How smoothly this works — and which method actually sticks — depends on a combination of factors: which device you primarily use Facebook on, whether you're using the app or a browser, your operating system version, and how your region settings are configured across your device and browser.
Someone using Facebook primarily through a mobile browser on Android will have a different experience than someone using the native iOS app, who in turn will find slightly different options than a desktop-first user. The right path forward depends on your own setup — which platform you're on, how your device's system language is set, and whether you need the change to persist across all your devices or just one.
