What is line-notifier.exe?
line-notifier.exe is the Windows background helper for LINE Notifier. It runs to deliver LINE notifications, sync message status, and keep the LINE desktop experience responsive. It activates on LINE activity and may run at Windows startup if configured.
This component runs as a separate process to handle notification events, message sync, and local badge updates, reducing the burden on the main LINE UI while improving responsiveness.
Quick Fact: LINE Notifier was designed to provide timely in-context notifications so you can respond to messages from the desktop without keeping LINE in focus.

- Sync Engine: Synchronizes read receipts and message status with LINE servers
- Settings Loader: Applies user notification preferences
- Updater: Checks for updates to the notifier component
- Network Listener: Maintains background network connection for push events
- Background Task: Handles lightweight background routines and timers

Is line-notifier.exe a Virus or Malware?
The legitimate line-notifier.exe is not a virus. Malware may counterfeit names; verify digital signatures and location.
How to Tell if line-notifier.exe is Legitimate or Malware
- File Location:: Must be in
C:\Program Files\LINE\Line Notifier\line-notifier.exe or C:\Program Files (x86)\LINE\Line Notifier\line-notifier.exe. Any other location is suspicious.
- Digital Signature:: Right-click the file in Explorer -> Properties -> Digital Signatures. Should show "LINE Corporation" as the signer.
