LINE uses Open Graph Protocol tags from websites to generate URL previews.

OGP tags used by LINE:

# Open Graph Protocol tag Example
1 og:title <meta property="og:title" content="LINE : Free Calls & Messages">
2 og:description <meta property="og:description" content="LINE is a new communication app">
3 og:image <meta property="og:image" content="http://static.naver.jp/line_lp/img/ogp.png">

Example of URL preview:

URL preview in chat


Even if you don't configure OGP tags, any text or image within the URL will be automatically retrieved to generate a URL preview.

For example, for the Title, if there is no available information in og:title, the text within the title tag will be displayed. Likewise, for the Summary, if there is no available information in og:description, the text within either the description tag or the body will be displayed (If there is no retrievable information, nothing will be displayed in the preview).


A cache-deletion tool (opens new window) for deleting the LINE server side cache of your URL preview is now available.

You cannot save or forward videos sent from a LINE Official Account if you are using LINE for iOS. Only users of LINE for Android can download, forward, and save videos on Keep.
