About this tool

OGG Vorbis is the free, open audio format beloved by game engines, open-source software, and the web. It compresses comparably to AAC, carries no licensing baggage, and is the native audio format for engines like Godot and countless HTML5 games. This converter produces OGG files entirely in your browser.

Game developers use it to prepare sound effects and music for their engines; podcasters and archivists choose it as an open long-term format; and Linux users often simply prefer it. Whatever the reason, the conversion never touches a server.

How to use

  1. Drag an audio or video file onto the page or browse for one.
  2. Encoding starts immediately with the Vorbis encoder at quality 5.
  3. Your .ogg file downloads automatically, with an inline preview player.
  4. Re-download any time with the completed ring.

FFmpeg compiled to WebAssembly performs the encoding on your own machine. Nothing about your audio is transmitted anywhere.

Frequently asked questions

Will OGG files play everywhere?

Browsers, Linux, Android, and games handle OGG happily. Apple platforms are the main holdout — for iPhones or iTunes, convert to M4A or MP3 instead.

Can I convert the audio from a video file?

Yes. Drop in any common video (MP4, MOV, WebM, MKV and more) and its audio track is extracted and converted automatically; the video stream is simply discarded.

Is my audio uploaded during conversion?

No. The conversion is performed by a WebAssembly build of FFmpeg running inside your browser tab. The file never leaves your device, and closing the tab removes it from memory.
