How to Submit LINE Emoji
Once you've downloaded the emoji ZIP from Stampo, follow these steps to apply on LINE
Before You Start
- You have downloaded the emoji ZIP from Stampo (contains 001.png–040.png and tab.png)
- LINE Creators Market account registration is complete (free)
- AI-generated emoji require checking the "Uses AI" box during submission
Method 1: Mobile Browser in Desktop Mode
As of 2026, the LINE emoji submission flow isn't available in the mobile app — you need to use a browser in desktop mode.
Switch your browser to desktop mode
Safari: long-press the address bar → "Request Desktop Website"
Chrome: tap the ⋮ menu → "Desktop site"
Log in to LINE Creators Market
creator.line.me Visit the site and log in with your LINE account.
Go to "Emoji" → "Submit new" and upload your files
Extract the ZIP, then upload each PNG one by one — emoji images (001.png– at 180×180 px) and tab.png (96×74 px). LINE generates the main image (240×240 px) automatically once you select emoji from your uploads.
Enter your title and description, then submit
Enter a title and description (Japanese & English). Check "Uses AI" and submit.
Method 2: PC Browser
Log in to LINE Creators Market
creator.line.me Visit the site and log in with your LINE account.
Go to "Emoji" → "Submit new"
Set the title (Japanese & English) and the number of emoji you exported (8 / 16 / 24 / 32 / 40).
Upload your images
Upload the files from the extracted ZIP — emoji images (001.png– at 180×180 px) and tab.png (96×74 px) in the appropriate slots. LINE generates the main image (240×240 px) automatically once you select emoji from your uploads.
Enter your description and submit
Enter a description in Japanese and English. Check "Uses AI" and click Submit.
About the Review Process
- Review typically takes a few hours to about 2 days (may be longer during busy periods)
- Check your review status on the LINE Creators Market dashboard
- If rejected, you'll be notified with a reason and can revise and resubmit
- Once approved, you can sell for a fee or distribute for free (as a gift)
Tips for Passing Review
- Backgrounds must be fully transparent (Stampo handles this automatically in the ZIP)
- No third-party likenesses or copyrighted characters (anime, celebrities, etc.)
- No violent or sexual content
- Emoji display small in chat — simple, instantly readable designs work best
- Don't forget to check "Uses AI"
