About WebM and OGG
WebM is the open web video container used by browser screen recorders and much of YouTube. Its audio track is typically Opus or Vorbis.
OGG Vorbis is a free, open lossy codec that beats MP3 at equivalent bitrates. It is common in game audio and open-source software, and every modern browser plays it.
Extracting audio from WebM re-encodes only the audio track — the video is discarded, so even long files finish quickly.
How the conversion works
This tool runs FFmpeg — the same engine behind most media software — compiled to WebAssembly, entirely in the browser. The file is read locally, converted locally and saved straight from memory; nothing is ever uploaded, which also means no queues and no server-side file size limits.
The converter itself is a one-time ~31 MB download on the first conversion, cached by the browser afterwards. Once it is loaded, everything works offline.
