Choose one clear subject
A single face, pet, character, or mascot usually produces cleaner stickers than a crowded group photo. The app needs to understand who the sticker pack is about before it can create consistent expressions.
Use photos with strong lighting
Good lighting helps preserve facial features, hair shape, clothing, and important character details. Avoid blurry photos, heavy shadows, and crops that remove the top of the head or hands.
Preview the whole pack
Do not judge the result by one sticker. Check whether the pack has reusable emotions such as hello, shocked, crying, side eye, happy, angry, thinking, and love before saving it.
