Requirements

Select your number of animated stickers from the Manage Stickers page. You can change this number freely before submission.
Generate your animated sticker images with an APNG creation tool such as APNG Assembler. Use ".png" for the filename extension.
Animated stickers' image files must adhere to the two following criteria.
- Their dimensions must be within 320 x 270.
- Either the width or height of the image must be at least 270 pixels.
* If you choose to make the height the longer side, it should be exactly 270 pixels.
Loops: 1 – 4 loops per sticker whose combined length does not exceed 4 seconds.
Playback time: Up to 4 seconds per sticker.
PNG frame limits per APNG: Between 5 and 20 frames.
* When creating APNG files with a creation tool such as APNG Assembler, repeated identical images may become combined as a single frame.
* Files that use the same data for all frames will fail to function properly as animated stickers and will result in an upload error.
Please ensure that your files are in RGB color space.
The maximum file size for each image is 1 MB. If submitting all images in a single ZIP file, make sure the ZIP file is 60 MB or smaller.
When creating stickers, please keep in mind that the first image of the APNG will be displayed as a static image on LINE STORE and the LINE Sticker Shop.
Image backgrounds must be transparent.
The small play symbol found in the top-right corner of the chat thumbnail icon is added automatically. Please do not add it yourself.
