PochiSta is a free, browser-based tool for making custom emoji and stickers. Text styling, AI background removal, animated GIF and APNG output, and per-platform export all run locally in your browser.

Emoji and stickers are read at the size they are pasted, not the size you drew them. It is built around the two problems that follow from that — “I made it, but it is too small to read in chat” and “it disappears against a dark background” — so you can check how it looks at its real size where it will be used, while you are still editing it.

• YouTube Live: Membership emoji / badge specs (1:1 transparent PNG)
• Twitch: Sub emote / bits badge upload set
• Discord: Server custom emoji (under 256KB) & custom stickers

• Microsoft Teams: Organisation custom emoji (under 256KB)

LINE stickers are exported separately, one image at a time, to the LINE Creators Market spec (370×320px with a 10px margin). They are not part of the bulk ZIP, and selling them requires going through LINE’s own review.

These platform specs were checked against the following official sources on 2026-08-23 (specs can change).

• Use custom emoji in Microsoft Teams (Microsoft Support)
• Custom emojis in Microsoft Teams (Microsoft Learn, admin)
