About OGG and Opus

OGG Vorbis is a free, open lossy codec that beats MP3 at equivalent bitrates. It's common in game audio and open-source software, and every modern browser plays it.

Opus is the newest codec here and the most efficient — it outperforms MP3, Vorbis, and AAC at low bitrates, which is why WhatsApp, Discord, and WebRTC all use it. Support is universal in browsers, patchier in older hardware.

Converting OGG to Opus is lossy. 192 kbps is transparent for most listeners on most material; pick 320 kbps if you want the ceiling, or drop lower when small files matter more than fidelity.

How the conversion works

This tool runs FFmpeg — the same engine behind most media software — compiled to WebAssembly, entirely in your browser. Your 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 your first conversion, cached by the browser afterwards. Once it's loaded, everything works offline.
