OGG is a container from the Xiph.Org Foundation, and the confusion around it comes from the fact that the extension does not tell you the codec. An .ogg file usually holds Vorbis, but it may hold Opus, FLAC or Speex. Vorbis was genuinely better than MP3 at the same bitrate and arrived with no patent licensing, which made it the natural choice for anyone who could not or would not pay for MP3.

That is why OGG survives in specific places rather than everywhere: games ship audio in it, Linux software defaults to it, Spotify streamed Vorbis for years, and open-source toolchains prefer it. What it never got was hardware. MP3 decoders were already in silicon when Vorbis appeared, and manufacturers had no reason to add a second codec — so car stereos, portable players and most consumer devices simply do not read OGG.
Converting to MP3 costs a little quality, since both are lossy and the encoder works from what Vorbis left rather than the original. It buys playback on all that hardware. Converting to WAV is the move when the audio is going into an editor or a game engine that wants uncompressed PCM — no further loss, at roughly ten times the size.

FAQ
What codec is inside my .ogg file?
Usually Vorbis, sometimes Opus, occasionally FLAC or Speex. The extension names the container, not the codec. All of them are decoded here, so the conversion works either way.
Why will my car stereo not play OGG?
Because Vorbis never made it into hardware decoders. MP3 was already established when it appeared, and manufacturers had no incentive to add another codec.
Is Vorbis better than MP3?
Slightly, at the same bitrate. But converting an existing OGG to MP3 cannot exploit that — it is a second lossy pass, so use 192 kbps or above to keep the total loss inaudible.
Where do OGG files come from?
Games, Linux software, older Spotify downloads and open-source tools, all of which favoured Vorbis because it carried no patent licensing.
OGG to MP3 or to WAV?
MP3 for listening on hardware that will not read OGG. WAV when the audio is going into an editor, sampler or game engine that wants uncompressed PCM.
Should I use Opus instead of Vorbis?
Technically Opus supersedes it in every respect. Vorbis remains the safer choice for older game engines and tools that predate Opus support.
