Supports: AVI
AVI is a Microsoft video container, so "converting" it to OGA does not keep the picture — it extracts the audio track and re-encodes it into an OGA (Ogg audio) file, discarding the video entirely. By default this tool encodes the output with Ogg Vorbis, the open, royalty-free codec from Xiph.Org, giving you a small, patent-free audio file suited to web embedding and Linux or open-source workflows. Whether the result is a clean single-generation encode or a lossy-to-lossy re-encode depends on what codec the AVI's audio track was already using — the tables and FAQs below explain exactly when each applies.
| Property | Value |
|---|---|
| Full name | Audio Video Interleave |
| Introduced | Microsoft, 1992 (part of Video for Windows) |
| Container family | A subformat of RIFF (Resource Interchange File Format) |
| Holds | A video stream plus one or more audio streams |
| Typical audio inside | MP3, AC-3, or uncompressed PCM (other codecs also possible) |
| What this tool keeps | The audio stream only — the video is discarded |
| Best for | Legacy Windows video; a common source when you only want the sound |
| Property | Value |
|---|---|
| Extension role | Audio-only Ogg, per Xiph's 2007 file-extension guidance |
| Default codec here | Ogg Vorbis (lossy); FLAC, Opus, and Speex also fit in Ogg audio |
| Container | Ogg — IETF RFC 3533 (2003); .oga registered by RFC 5334 (2008) |
| MIME type | audio/ogg (shared with .ogg) |
| Compression | Lossy (Vorbis): variable bitrate that adapts to signal complexity |
| Licensing | Open, royalty-free — no MP3/AAC patent history |
| Best for | Web audio, Wikimedia-style audio, Linux/open-source pipelines, smaller files |
Because Vorbis is a lossy codec, the honest answer depends on what was already inside the AVI:
Either way, keep the original AVI if you might need the audio at full quality later; lossy encoding is not reversible.
.oga file. No sign-up, no watermark.Only the audio. OGA is an audio-only format, so this conversion extracts the sound track from the AVI and re-encodes it, leaving the video behind. If you need to keep the picture, convert the AVI to a video format instead; if you want just the sound in a different audio format, convert AVI to MP3 for the most universally playable result.
It depends on the AVI's audio. If that track is already MP3 or AC-3 (both lossy), encoding to Vorbis is a second lossy generation, so match or exceed the original bitrate to minimize added loss. If the AVI holds uncompressed PCM, you get a clean single-generation Vorbis encode with only the one expected loss. Vorbis sounds transparent to most listeners from roughly 160-192 kbps upward, so the difference is usually small at sensible bitrates.
They share the same Ogg container and audio/ogg MIME type, so most modern players treat them identically. The difference is convention: since Xiph's 2007 guidance, .ogg is reserved for legacy Vorbis-only audio while .oga is the general audio-only extension that can also hold FLAC, Opus, or Speex. A few older apps and hardware players misread the .oga spelling — if you want the more widely recognized label for the same Vorbis audio, convert AVI to OGG instead, which writes .ogg.
Vorbis is fully open and royalty-free, and at similar bitrates it is widely regarded as matching or beating MP3 in listening tests, especially below 192 kbps. OGA is the natural fit for Ogg-centric, Wikimedia-style, and Linux or open-source audio pipelines. The trade-off is reach: MP3 plays on virtually every device, while Ogg support is spottier on Safari and some hardware. When broad compatibility matters more than openness, convert AVI to MP3.
The Ogg container can carry FLAC (lossless), Opus, or Speex in addition to Vorbis, and Vorbis is simply the default here because it is the most widely playable .oga codec. But lossless only matters if the AVI's audio was lossless to begin with — most AVI tracks are MP3 or AC-3, which are already lossy, so wrapping them losslessly would preserve, not restore, quality while making the file larger. There is no benefit to a lossless wrapper around already-lossy audio.
Native Ogg Vorbis playback is built into Firefox, Chrome, Edge, Opera, Android, and most Linux audio stacks, plus desktop players like VLC and foobar2000. Safari and some hardware players (car stereos, older portable devices) have spottier Ogg support — for those, MP3 is the safer bet. In our testing, an .oga produced at the default preset played without installing extra codecs in current Chrome and Firefox.
Your AVI is uploaded over an encrypted connection, the audio is extracted and converted on our servers, and the files are deleted automatically a few hours after conversion. There is no sign-up, no watermark, and your files are never shared or made public. For size-driven jobs across many audio formats, the Audio Compressor adds a target-size control.
