Sticker Maker: Turn Photos into Stickers
Upload a photo and the AI cuts out the subject automatically, then adds a white outline, a shadow and an optional caption or speech bubble to make a ready-to-use sticker. Pick a size for Telegram or LINE stickers, print stickers, or a KakaoTalk emoticon draft.

How to use
- Upload photos with a clear outline, such as people, pets or products (you can add several).
- Wait a moment while the AI removes the background (the model loads only the first time; after that it's faster).
- Adjust the outline width, color and shadow, and add a speech bubble and caption if you like.
- Pick a size preset for your use: Telegram/LINE sticker 512×512, print sticker (mm, 300 dpi), or KakaoTalk emoticon proposal 360×360 (unofficial reference).
- Save as a transparent PNG or WebP, or get several at once as a ZIP.
Copyright note: don't turn images you don't have rights to (characters drawn by others, screenshots of famous content, photos of other people's faces) into stickers and share them without permission. Only use photos you took or images you have permission to use.
Tips
The clearer the contrast between the subject and the background, as in pet or portrait photos, the cleaner the AI cutout. Thin, complex edges like hair or fur may not be removed perfectly; raising the white outline width by 2–3px makes leftover edges much less noticeable. Adding a light shadow makes the sticker stand out whether the chat background is light or dark.
For Telegram and LINE-style messenger stickers, the official rule is that one side must be exactly 512px (per Telegram's official documentation). Save as a transparent PNG or WEBP. For print stickers (planner decorations, packaging labels), enter the real print size in mm and it is converted to pixels at 300 dpi, so the outline stays sharp after printing.
The 360×360 preset for KakaoTalk (a Korean messenger app) emoticon proposals is a reference size mentioned across many creator guides. Kakao's exact official submission spec can only be checked after logging in to Kakao Emoticon Studio (emoticonstudio.kakao.com), so we label this preset as an unofficial reference.
To make many stickers in the same style (outline color and width, font), upload all the photos at once, set the options once and download them as a ZIP instead of saving each one.
FAQ
Are the Telegram and LINE sticker sizes accurate?
Yes. Per Telegram's official documentation, a static sticker must have one side of exactly 512px and the other 512px or less, in PNG or WEBP with a transparent background. The 512×512 preset in this tool follows that rule.
Do some photos not cut out well?
Photos with a clear outline, such as people, pets and products, work well. Subjects with colors close to the background, or thin, complex edges like hair, may not be perfect. Making the outline a little thicker helps hide rough edges.
Is the KakaoTalk emoticon size correct?
360×360px is a reference size mentioned in many creator guides, but Kakao Emoticon Studio's official submission spec can only be checked after logging in, so this site offers it as an unofficial reference. Before submitting a proposal, always confirm the latest spec at emoticonstudio.kakao.com.
Can I make stickers from other people's photos or characters?
You may not turn copyrighted characters or other people's photos or likenesses into stickers and share them without the rights holder's permission. Only use photos you took yourself or images you have permission to use.
