How to Back Up LINE Chats: Full Guide

This guide shows you how to back up your LINE chat history on both iPhone and Android, so you never lose important conversations when switching phones, reinstalling the app, or after a device failure. You’ll learn the built-in backup methods, how to restore chats, and what to do when backups fail.

What You’ll Need

Your phone with LINE installed and logged in
For iPhone: iCloud account with enough storage (free 5GB may not be enough)
For Android: Google Drive account with enough storage (free 15GB usually works)
A stable Wi-Fi connection (backups can be large)
Your LINE account password or the ability to receive a verification code (for re-login)

Step-by-Step

Backing Up on iPhone (iCloud)

Open LINE on your iPhone.
Tap the Home tab (the speech bubble icon at the bottom).
Tap your profile photo or the Settings gear icon in the top-right corner.
Select Chats (or Chat Settings depending on your version).
Tap Back up chat history.
You’ll see the last backup date and size. Tap Back up now.
Wait for the backup to complete. Do not close the app or switch networks.
To enable automatic backups, toggle on Automatic backup and choose a frequency (daily, weekly, etc.).

Backing Up on Android (Google Drive)

Open LINE on your Android phone.
Tap the Home tab, then your profile photo or the Settings gear icon.
Select Chats (or Chat Settings).
Tap Back up and restore (or Back up chat history).
If prompted, link your Google account. If not, tap Back up to Google Drive.
Tap Back up now.
Wait for the backup to finish. You’ll see a confirmation with the time and size.
To automate, tap Auto backup and select a schedule.

Restoring a Backup (When Reinstalling or Switching Phones)

Install LINE on your new phone and open it.
Tap Log in and enter your phone number.
Verify your number with the SMS code.
When asked, enter your LINE password (if you have one). If not, you may need to verify via email or Facebook.
After logging in, LINE will detect a backup. Tap Restore.
For iPhone, make sure you’re signed into the same iCloud account. For Android, the same Google account.
Wait for the restore to complete. Do not force-close the app.
Your chat history should reappear. Note: some media (photos, videos) may not restore if they were not backed up.

Common Mistakes

Not enough cloud storage: iCloud free tier (5GB) often fills up. Google Drive free tier (15GB) is usually enough, but large chat histories may exceed it. Check your storage before backing up.
Backing up without Wi-Fi: Backups can be hundreds of MB. Using cellular data may fail or incur charges.
Logging out before backing up: If you log out of LINE without backing up, you lose all chats. Always back up before logging out.
Restoring on a different OS: You cannot restore an iPhone backup to an Android phone or vice versa. Backups are platform-specific.
Ignoring the “last backup” date: If your last backup is old, you’ll lose recent chats. Check the date before restoring.

Tips

Back up regularly—weekly is a good habit if you chat a lot.
Keep your LINE app updated to avoid backup compatibility issues.
If you have important media, consider saving it separately (e.g., to your camera roll) because backups may not include all media.
Use the same Apple ID/Google account for LINE backups that you use for your phone’s system backup (iCloud/Google Drive).
Before restoring, make sure your phone’s date and time are set correctly—incorrect settings can cause restore errors.

Troubleshooting

Backup fails or gets stuck

Check your internet connection. Switch from Wi-Fi to cellular or vice versa.
Free up cloud storage. Delete old backups or files.
Restart the LINE app and try again.
Update LINE to the latest version.

Restore fails

Make sure you’re using the same phone number and account as when the backup was made.
Verify you’re signed into the correct iCloud/Google account.
If you get an error, try logging out of LINE and logging back in, then attempt restore again.
If the restore is stuck on “Restoring”, leave the app open and wait—it can take a while for large backups.

Chat history is missing after restore

Check the backup date—you may have restored an old backup.
Some chats may not restore if they were deleted before the backup.
Media files (images, videos) may be missing if they weren’t included in the backup. This is normal.

“No backup found” message

Ensure you are logged into the same account that created the backup.
For Android, confirm you’re using the same Google account that was linked in LINE’s backup settings.
If you switched from iPhone to Android (or vice versa), backups are not transferable—you’ll need to start fresh.

Frequently Asked Questions

Does LINE backup include photos and videos?

Backups include chat text and some media, but large files (especially videos) may be excluded. Media that is older than a certain time may also be omitted. For important media, save it separately.

Can I back up LINE chats to my computer?

LINE does not offer a direct PC backup for chat history. You can only back up to iCloud (iPhone) or Google Drive (Android). However, you can use LINE’s “Export chat” feature (in chat settings) to save a text file of a conversation, but this does not include media.

How long does a LINE backup take?

It depends on the size of your chat history and your internet speed. Small backups may take a minute; large ones can take 10-20 minutes. Keep the app open and connected.

Will I lose my chats if I log out of LINE?

Yes, if you log out without backing up, your chats are deleted from the device. Always back up before logging out, and restore after logging back in.

Can I restore a backup from a friend’s phone?

No, backups are tied to your LINE account and phone number. You cannot restore someone else’s backup to your account.

What if I forgot my LINE password?

You can still log in with your phone number and a verification code. If you have a backup, you can restore it after logging in. To reset your password, use the “Forgot password” link on the login screen.
