Cubemap

Equirect 360 video to cube faces

Extract frames from an equirectangular video, a YouTube 360 EAC link, or a ZIP of still frames — trim to a start/end window, project selected cube faces with custom FOV, and write images straight to a local folder.

Input video or ZIP

YouTube 360 link

Saves the YouTube video into a folder you choose (Chrome/Edge), then loads it for cubemap export — no apps to install. 360/EAC videos are processed with Input projection set to YouTube EAC. If YouTube blocks the session, Choose file with a copy you already have.

Private by design

Cubemap projection, frame extraction, and optional mask inference run in your browser with WebGL. Local files never leave the device. YouTube “Save to folder & process” resolves the stream on the host with a JavaScript library (no yt-dlp/ffmpeg install), then proxies bytes so your browser can write the file to a folder you pick. Cubemap processing stays on-device. Only use videos you have rights to process.
