Really easy to use, and the image quality is great.
Frequently asked questions
How much does it cost?
Creating is free. You only pay when you download the finished set: 8 for ¥500, 16 for ¥980, 24 for ¥1,380, 32 for ¥1,780, 40 for ¥1,980 - a one-time payment. There is no monthly fee. You pay by credit or debit card (including Apple Pay and Google Pay) on Stripe's checkout page.
How many stickers are in a set?
To match LINE's sticker specification you can choose 8, 16, 24, 32 or 40. In the free trial, whichever size you choose, we generate the first 4 so you can check the result. The rest are generated automatically after purchase.
What format do I get?
A ZIP you can submit to LINE Creators Market as-is. It contains the stickers themselves (max 370x320px, even pixel sizes, transparent PNG)、a main image of 240x240px、a tab image of 96x74px, and metadata in Japanese and English that you can paste into the submission form. You can also download a ZIP converted for Discord stickers, Slack/Teams emoji, WhatsApp and Telegram.
Do you check whether it will pass LINE's review?
We automatically check only what a machine can judge. Specifically: (1) image size and even pixel dimensions, (2) whether the background is transparent, (3) whether stray pixels remain at the edges, and (4) whether the same picture has been reused. Any sticker that fails is regenerated automatically before the ZIP is made.
However, this is not a guarantee that your stickers will pass review. We cannot prevent rejections for reasons that cannot be judged from the image data alone, such as copyright or portrait-rights infringement, or problems in the description. The criteria are explained in our guide to submitting to LINE and avoiding rejection.
Which platforms can I use the stickers on?
Besides LINE (we build the Creators Market submission ZIP automatically), you can download versions converted for Discord stickers, Slack and Teams emoji, WhatsApp and Telegram.
How is this different from making images with ChatGPT or Gemini?
A general image AI can draw the pictures too. The difference is everything that comes after: getting them into LINE sticker shape. To submit to LINE Creators Market you have to make each image transparent, fit it within 370x320px with even pixel dimensions and a margin, prepare a main image (240x240px) and a tab image (96x74px), and bundle it all into a ZIP. General AI tools usually output several pictures merged into one image, so splitting, background removal, resizing and file naming are left to you by hand. STAMP ENGINE does that finishing automatically and gives you a submission ZIP you can upload without unpacking. On top of that, the character stays the same across all 8 to 40 expressions, which is hard when you regenerate one picture at a time.
How long does it take?
The free preview (4 stickers) takes about 1 to 2 minutes. After purchase we generate the rest automatically; a set of 8 is finished within a few minutes.
How do I receive the stickers after paying?
You can download the ZIP from the page right away. If you entered an email address, we also send the finished submission ZIP as an attachment, so you have a copy to retrieve later.
What kind of photo works best?
A bright photo facing forward, with the hair and outline clearly visible, works best. Please use only photos you have the rights and consent to use - yourself, your family or your own pet.
Who owns the stickers I create?
Once purchased, the stickers are yours to use commercially or non-commercially. You can also sell them on LINE Creators Market (we recommend declaring that AI was used when you submit).
What if I do not like the result?
You can check the result in the free preview before buying, and redo any single sticker you do not like. You only pay once you are happy, so there is no risk in paying up front.
