How to Make LINE Stickers with AI
You don't need to draw — AI can turn a single photo into a full, expressive LINE sticker pack. Here's the whole process in five simple steps.
必要なもの
- A clear photo of your subject
- A concept (pet, yourself, a friend)
- The SeishunAI app
- 💡
ステップ 1
Choose your concept
Decide what your pack will feature — your pet, a cartoon of yourself, a couple, or an original character. A clear idea makes every later step easier.
- 🖼️
ステップ 2
Upload a clear photo
Pick a well-lit photo where the face is clearly visible and the background isn't cluttered. This gives the AI the best reference to work from.
- 🎭
ステップ 3
Pick your expressions
Choose the emotions you want — happy, laughing, sad, surprised, love. These become the individual stickers in your pack.
- ✨
ステップ 4
Generate the pack
Let the AI build every sticker from your photo, keeping the same character consistent across each pose and expression.
- 📲
ステップ 5
Export LINE-ready
Download your pack already sized and formatted for LINE (370×320 px, transparent background). No manual resizing needed.
コツ
- Front-facing photos with a clear expression produce the best likeness.
- Start with 2–3 core expressions, then expand once you like the style.
- A plain background helps the AI isolate your subject cleanly.
