PochiSta is a completely free, browser-based emote maker for VTubers, streamers and Discord/Slack community managers. Build text emotes that stay readable in chat using heavy display fonts and multi-layer outlines, cut out character art with in-browser AI, and export transparent PNGs and animations (GIF, plus full-colour APNG for Discord stickers) optimised for each platform's spec in one click.
Your images never leave the browser, so unreleased character art and fan art stay private.
| Platform | Static (transparent PNG) | Animated |
|---|---|---|
| YouTube Live | 480×480px | Not supported (static only) |
| Twitch | 112×112px 56×56px 28×28px | 112×112px (max 1024KB) 56×56px (max 1024KB) 28×28px (max 1024KB) |
| Discord | 128×128px (max 256KB) 320×320px (max 512KB) | 128×128px (max 256KB) 320×320px (max 512KB) |
| Slack | 128×128px (max 128KB) | 128×128px (max 128KB) |
Yes. It is completely free and no account is required. You can use the emotes you create commercially — every bundled font ships under a permissive licence such as the SIL Open Font License.
No. Everything — AI background removal, outlining, resizing and ZIP packaging — runs inside your browser, and nothing is uploaded or stored on a server. Even the AI model is served by this site itself, so nothing reaches an external server.
Twitch emotes require a set of three sizes: 112×112px, 56×56px and 28×28px. PochiSta exports all three as transparent PNGs in one click. Animated emotes are supported as GIFs up to 1MB.
Discord custom emoji (128×128px recommended) must be 256KB or smaller. PochiSta automatically reduces colours and compresses the output so it stays under the limit. Stickers (320×320px) are kept under 512KB.
Slack custom emoji are 128×128px with a 128KB file size limit — stricter than the other platforms. PochiSta compresses automatically to stay within it, and animated GIFs follow the same rule.
No. YouTube membership emoji are static images only (480×480px transparent PNG recommended). Even with an animation selected, PochiSta exports a static PNG for YouTube.
