How to Make Custom LINE Emoji
LINE emoji are the tiny, inline cousins of stickers — perfect for quick reactions. Here's how to make a custom set.
必要なもの

ステップ 1
Plan your emoji set
Emoji are read at tiny sizes, so pick simple, punchy ideas — single expressions, hearts, reactions — that stay clear when small.
- 📐
ステップ 2
Know the size rules
LINE emoji are 180×180 px with a transparent background. Keep the design bold and centered so it reads at a glance.
- 🎨
ステップ 3
Design or generate each one
Create each emoji in a consistent style. AI can generate a matching set from a character so they all feel related.
- 📤
ステップ 4
Export and publish
Export transparent PNGs at 180×180 px, then submit through the LINE Creators Market to publish your set.
コツ
- Simplicity wins — emoji are much smaller than stickers, so avoid fine detail.
- A consistent character across the set makes it feel like a real product.
