FAQ
About LINE sticker and emoji image sizes
What size are LINE stickers?
Stickers are up to 370×320 pixels (even numbers), the main image is 240×240 and the chat room tab image is 96×74. All are transparent PNGs of 1MB or less.
What size are LINE emoji?
Emoji are 180×180 transparent PNGs, submitted in sets of 8 to 40. The official guide recommends drawing to the edges without a margin.
Are my images uploaded?
No. Everything happens in your browser; images never leave your device.
Can it remove a white background?
Turn on "Make the white background transparent" and the white connected to the image edges becomes transparent. If the outline has gaps, white inside can disappear too - check on the dark preview.
Can it split one image with many drawings?
Yes. Pick a layout such as 4×3 under "Split one image" and it cuts along the white gaps. Works with sticker sheets made in ChatGPT or Gemini.
How are the files named?
The way LINE Creators Market expects: stickers 01.png…, emoji 001.png…, main.png and tab.png.
Can't draw? Get all 40 anyway.
