Asked on May 2, 2026

LINE can be used on Windows in a few different ways, depending on what you need (chatting, calls, or notifications). The most common option is installing the official LINE desktop app for Windows, which keeps your conversations synced with your LINE account. If you prefer not to install software, you can also use LINE in a web browser. In this guide, you’ll find practical steps for setup, sign-in, notifications, and troubleshooting so you can start using LINE on Windows quickly.

Method 1: Install the official LINE app for Windows

Steps:

  • Download the official LINE Windows app from the LINE website or the Microsoft Store (if available for your region).
  • Install the app by running the installer and following the on-screen prompts.
  • Open LINE after installation.
  • Sign in using your existing LINE account (typically by scanning a QR code with your phone).
  • Allow notifications when prompted so you receive messages and calls alerts.

Method 2: Use LINE in a browser (no install)

If you don’t want to install an app, you can use LINE through a browser-based experience (where supported). This is useful for quick access, shared computers, or troubleshooting app issues.

  • Open your browser and go to the LINE web entry point.
  • Sign in with your LINE account using the QR code method.
  • Check browser notification permissions if you want message alerts.

How to sign in safely (QR code)

Most LINE desktop/web sign-ins use a QR code. To keep your account secure:

  • Only scan QR codes shown on your own device.
  • Make sure you’re on the official LINE site/app.
  • If you don’t recognize the sign-in prompt, stop and secure your account.

Common troubleshooting

1) QR code won’t scan or keeps expiring

  • Ensure your phone camera is focused and has good lighting.
  • Try again after refreshing the QR code in the LINE app.
  • Check that both devices are connected to the internet.

2) Notifications not working

  • In Windows, confirm notification permissions for LINE.
  • In the LINE app settings, verify notification options are enabled.
  • Check Windows Focus Assist / Do Not Disturb settings.

3) App won’t open or crashes

  • Update LINE to the latest version.
  • Restart your PC and try again.
  • Temporarily disable VPN/proxy if you use one.

Which option should you choose?

  • Best overall experience: Install the official LINE Windows app.
  • No installation: Use the browser option (if available).
  • Shared or managed devices: Browser mode can be more convenient.
