How to Turn a Photo into a Sticker
A favorite photo of your pet, your friend, or yourself is all you need. Here's how to turn it into a clean, shareable sticker.
必要なもの
- A photo you love
- SeishunAI (or a background remover for manual edits)
- 🔍
ステップ 1
Pick and crop the photo
Choose a photo where your subject is clearly in focus. Crop in close so the subject fills most of the frame.
- ✂️
ステップ 2
Remove the background
Cut out the background so the subject sits on transparency. AI tools do this automatically; manual editors need a background-remover tool.
- 🎨
ステップ 3
Add a sticker style
Give it a sticker look — a clean outline, a cartoon effect, or a consistent art style so it reads as a sticker, not just a cutout.
- 📐
ステップ 4
Size and export
Export as a transparent PNG at the size your chat app needs. For LINE that's 370×320 px; SeishunAI handles this for you.
コツ
- Close-up photos with a clear subject cut out far more cleanly.
- Turning one photo into several expressions makes a whole pack, not just one sticker.
