LINE Emoji Submission Guidelines | Passing the Review
A practical guide to the LINE emoji review process. Covers required dimensions, visibility tips, and prohibited content.
Table of Contents
Dimensions and Visibility
LINE emojis must be exactly 180x180 pixels. Since emojis are displayed very small in text, fill the canvas and avoid adding margins. Extra whitespace makes the emoji look even smaller and may lead to rejection for poor visibility.
Animation Logic (First Frame)
Animated emojis have a strict file size limit of 300KB. The first frame is used as the static placeholder. Ensure the first frame represents the core meaning, especially for text-based emojis (Deco-moji).
Detailed Prohibitions & Common Rejections
Ensure your emoji set doesn't fall into these common rejection categories:
- Images: No duplicate images. Avoid subtle differences that users cannot distinguish.
- Metadata: No URLs or emojis in titles. Avoid announcement text.
- Morals: Prohibit excessive skin exposure, violence, or content encouraging illegal substances.
- Rights: Never use third-party characters or portraits without explicit permission.
