Searching for LINE on PC specifically usually means you already use it on mobile for chatting with contacts in Japan, Thailand, or Taiwan and want the same conversations open on a bigger screen while working. What catches people off guard is that the desktop app isn't a standalone account, it has to be linked to an existing LINE account already set up on a phone. This page has the free PC installer and explains that pairing step before you hit a login wall.
Desktop Requires an Existing Phone Account
LINE's desktop app cannot create a new account by itself; you first need to register a LINE account on a phone using a mobile number, then log into the PC app by scanning a QR code or entering credentials to pair it as a linked device.
Once paired, messages sync in both directions between phone and PC automatically, but if your phone number changes later, you'll need to re-verify from the mobile app, not from the desktop client.
Who ends up using LINE
People staying in touch with friends, family, or coworkers in Japan, Thailand, or Taiwan, where LINE is the dominant messaging app, install it for desktop convenience.
- Users chatting with contacts in Japan, Thailand, or Taiwan where LINE dominates
- People wanting to type longer messages on a keyboard instead of a phone
- Small businesses in LINE-heavy markets managing customer chats from a PC
Before you install
A couple of things worth knowing about LINE before you request the link: it covers Windows, macOS, Android and iOS, so pick the right build for the machine you're setting up. And on pricing, LINE is free to use outright — there's no paid tier hiding behind it, so what you install is the whole app. It's developed and maintained by LINE Corporation.
System requirements
- WindowsWindows 10 or 11 (64-bit); older 7/8.1 builds usually still run but no longer get official support
- macOSa recent macOS release — check the download page for the current minimum version, since Apple Silicon vs Intel builds sometimes differ
- Androida recent Android build installed from the Play Store or the developer's own APK
- iOSa recent iOS release installed from the App Store
It's a lightweight tool, so there's no serious CPU/RAM/storage requirement beyond what its OS already needs to run comfortably.
Quick steps
- Set up a LINE account on your phone first if you haven't already
- Install the PC app and choose to log in via QR code
- Scan the code shown on PC using the LINE app's QR scanner on your phone
LINE: the honest trade-offs
- Messages sync instantly between phone and desktop once paired
- Free voice and video calling works reliably alongside text chat
- Sticker and timeline features carry over fully from the mobile app
- Desktop app cannot create a new account, only pairs with an existing one
- Less widely used outside East and Southeast Asia, limiting its usefulness elsewhere

Keeping LINE up to date
LINE usually has a built-in updater or store-based auto-update (Microsoft Store / Mac App Store / Play Store, depending on platform); if you installed it manually, re-downloading the current build from the official source is the fallback. Sticking to the developer's own distribution channel — which is what this page links to — means you're never stuck on an old build with unpatched bugs just because a mirror site stopped updating its copy.

Frequently asked questions
Can I create a new LINE account directly from the PC app?
No, account creation requires a phone number and is done through the mobile app; the PC client only logs into an existing account.
Does closing the PC app log me out of LINE on my phone?
No, both devices stay independently logged in once paired, and messages continue syncing to both until you manually log out.
