Supports: OGV
OGV is the Ogg video container — it holds Theora video alongside a Vorbis audio track. AIFC (AIFF-C) is Apple's audio container, the format Mac audio tools reach for. This conversion is an audio extraction: it pulls the Vorbis soundtrack out of the OGV, discards the video entirely, and re-wraps the audio as an AIFC file. The result is sound only — there is no picture in an AIFC.
One honest note up front: the audio inside an OGV is Vorbis, which is lossy. Encoding it to uncompressed PCM inside AIFC does not restore detail that Vorbis already discarded — it simply stores the existing audio in a larger, Mac-friendly wrapper. AIFC is useful here for ecosystem compatibility, not for a quality gain. If you mainly want a small, portable file, convert OGV to MP3 instead.
| Property | Value |
|---|---|
| Container | Ogg (.ogv), maintained by the Xiph.Org Foundation |
| File suffix | .ogv recommended by Xiph.Org since 2007 |
| Video codec | Theora (lossy; VP3-derived, spec frozen June 2004, libtheora 1.0 in Nov 2008) |
| Audio codec | Vorbis (lossy, roughly 16–500 kbit/s per channel) |
| Licensing | Royalty-free, open, patent-unencumbered |
| Best for | Open-web video playback; Wikimedia and open-source projects |
| Property | Value |
|---|---|
| Container | AIFF-C (Audio IFF, Compressed), introduced by Apple in July 1991 |
| File suffix | .aifc preferred; .aif/.aiff also accepted by many apps |
| Payload | Either uncompressed PCM (compression type "NONE") or a compressed codec |
| Default here | 16-bit PCM, big-endian — uncompressed, lossless storage |
| Origin | Extension of Apple's AIFF, based on the IFF chunk structure |
| Best for | macOS, Logic Pro, GarageBand, and other Apple-ecosystem audio tools |
.ogv into the box or click "Add Files." You can queue several clips and convert them with the same settings.No. The audio in an OGV is Vorbis, a lossy codec, so any detail it dropped is already gone. Encoding to uncompressed PCM inside AIFC preserves what is left exactly — it cannot reconstruct what was discarded. You get a faithful, lossless copy of the lossy source, not a higher-fidelity master.
No. AIFC is an audio-only container, so the Theora video stream is discarded during conversion. Only the soundtrack is extracted and re-wrapped. If you need the video, use a video-to-video tool such as our OGV converter instead.
The OGV stores audio compressed with Vorbis, while the default AIFC here stores uncompressed 16-bit PCM. Uncompressed audio runs at roughly 1.4 Mbit/s for CD-quality stereo, so an AIFC of the same audio is typically several times larger than the Vorbis track it came from. That is expected for a PCM wrapper.
Plain AIFF stores only uncompressed PCM. AIFF-C (AIFC) extends that format so it can also hold compressed codecs, while still supporting uncompressed PCM with the compression type set to "NONE." In practice, an AIFC holding PCM is effectively an AIFF with a more flexible header. If you specifically need classic AIFF, use our OGV to AIFF tool.
AIFC is an Apple format, so macOS apps handle it natively — QuickTime, Music, Logic Pro, and GarageBand all read it. Many cross-platform audio editors such as Audacity also import AIFF-C. On Windows, support is less universal, which is one reason to choose MP3 when sharing broadly.
Your OGV is uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours. There is no sign-up, no watermark, and files are never shared or made public. In our testing, a typical short OGV clip extracts and re-encodes to AIFC in a few seconds; the main wait on large files is upload time, not processing.
