Convert an OGG file to WAV
Convert your OGG (Vorbis) files to WAV directly in your browser (WebAssembly) — nothing is sent to a server. Select one or more OGG files then start the conversion (max 50 MB per file).
Note: only OGG → WAV conversion is available here. The reverse conversion (WAV → OGG) would require a native Vorbis encoder that has no mature, WebAssembly-compatible pure Rust equivalent at the moment.
How it works
The OGG (Vorbis) format is used by many video games for their sound effects and music, as well as by some open-source software, precisely because it's royalty-free and well compressed. But to edit, cut or remix a sound extracted from a game or an OGG project in a standard audio editing tool, it's often simpler to work from an uncompressed stream. This tool decodes your OGG file and rebuilds a WAV containing the PCM samples, directly importable into an editing tool.
Why isn't the WAV to OGG direction available?
Encoding to Vorbis requires a native encoder comparable to libvorbis, for which there is no pure Rust implementation today that's mature and reliable enough to be compiled into WebAssembly. Decoding an existing OGG stream (playback) is, on the other hand, well supported, which enables the OGG → WAV conversion offered here.
Is OGG a royalty-free format?
Yes. Unlike MP3, whose historical patents long complicated its open implementation (they have now expired), the Ogg container format and the Vorbis codec were always designed as open standards, with no royalty or license to pay for developers or software vendors.
Privacy: the conversion runs entirely in your browser via WebAssembly — your audio files are never sent to a server.
