For the best results across all channels, use the following file types and sizes:

Images: JPG/JPEG and PNG are supported across all channels.

  • Facebook: For optimal performance, keep image sizes under 1MB.

LINE Videos: Use MOV or MP4 format. Supports common file types, e.g., csv, pdf, txt, excel, psd, ai, ppt, docx, doc. (Does not support .exe file format.)

How to Use

Tap the “+” button (see arrow in the image below) to choose the type of file you want to send (Image / Video / Audio / File). The following example uses “File.”

Uploading files on LINE

File download expiry (LINE only):

  • Currently, expiry applies only to 1:1 messages. Saved replies and broadcast messages are not subject to expiry.

  • The validity is fixed at one month, calculated in UTC time. For example: If a file is uploaded on Sep 15 at 11:49 (local time), it will be recorded as Sep 16 at 00:00 UTC. Adding 30 days, the expiry date will be Oct 16 at 08:00 (local time).
