Message types


Message type icons (from left to right): Text, Sticker, Photo, Coupon, Rich message, Rich video message, Video, Voice message, Surveys, Card-based message, Reservation form.

See below for information about each icon.


  • Text

You can enter up to 500 characters per text message. (This includes half-width and full-width characters, symbols, etc.) You can also use the Emoji button to add emoji and emoticons.
- Please be aware that emoji will appear as text descriptions in notifications that users receive on their devices.
- If you include a URL in your text message, an image from the site may appear as a thumbnail. This thumbnail is a preview based on the Open Graph Protocol (OGP) metadata in the linked site's HTML head tag. Because this information is handled by the site manager, you cannot specify the preview image that appears in LINE Official Account Manager.

  • Sticker

You can send stickers from the standard LINE sticker sets.
Note: Other sticker sets cannot be used.

  • Photo

To send a photo saved on your PC, click Upload photo and select the photo you want to send.
- You can send photos of up to 10 MB in size.
- Photos are compressed when they are uploaded on LINE Official Account Manager. This may lower the resolution of a photo and change the way it appears, so we recommend checking how your photo will look before sending it out (e.g. with a test account).
