Common questions

Everything you need to know

Your animation runs in a hidden frame where browser time is frozen and stepped frame-by-frame (Virtual Time engine). Each frame is captured and encoded with the native WebCodecs API — zero dropped frames on any machine. Optional audio is mixed in with AudioEncoder before muxing.

MP4 (H.264) for social platforms, WebM (VP9) for the web (with optional transparency), and GIF for sharing. Aspect ratios: 16:9 landscape, 9:16 vertical for Reels/TikTok/Shorts, and 1:1 square — up to 4K at 60fps.

Click AI Generate, describe the animation you want, and paste your own Gemini API key (stored only in your browser). The AI writes the HTML/CSS/JS and loads it straight into the editor for you to tweak.

Completely free. No watermark, no sign-up, no limits. Everything runs client-side — your projects save to your own browser.

Yes — add any audio file in the Audio section. It's automatically trimmed to your video's length and mixed into MP4/WebM exports.

Browser Not Supported

Video export needs the WebCodecs API (Chrome 94+, Edge 94+, Brave desktop). The editor and preview still work here.
