What Are LINE Stickers?
LINE stickers (called “stamps” in Japan) are custom illustrations or photos used as expressive messages in the LINE messaging app. Creators can design and sell their own sticker packs through the LINE Creators Market — or simply make personal stickers for fun.

Design Tips for Popular Stickers
Keep It Simple
LINE stickers appear small on phone screens. Bold outlines, simple shapes, and minimal text work best. Fine detail gets lost at display size.
Show Emotion Clearly
The best-selling stickers convey emotions instantly — happiness, frustration, gratitude, sarcasm. Exaggerated facial expressions and body language outperform subtle ones.
Use a Consistent Style
A sticker pack should feel cohesive. Use the same character, color palette, and line weight across all stickers. Extract consistent colors with the Color Palette tool.
Plan Your Set
Map out the emotions and phrases you want to cover before drawing:
- Greetings (hello, goodbye, good morning)
- Reactions (OK, thank you, sorry, LOL)
- Emotions (happy, sad, angry, surprised)
- Actions (eating, sleeping, working, celebrating)
Submitting to LINE Creators Market
- Create a LINE Creators account at creator.line.me
- Upload your sticker set (main image, tab image, and all stickers)
- Fill in title, description, and pricing
- Submit for review (typically 1–3 days)
- Once approved, your stickers go live in the LINE Sticker Shop
