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.
OGV Format at a Glance
| 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 |
AIFC Format at a Glance
| 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 |
How to Convert OGV to AIFC
- Upload Your OGV File: Drag and drop your
.ogvinto the box or click "Add Files." You can queue several clips and convert them with the same settings. - Pick the Audio Codec: Open Advanced Options to choose the AIFC payload — the default is PCM 16-bit Big Endian (uncompressed). PCM 24-bit, A-law, or mu-law are also available if a tool requires them.
- Set Audio Channel and Sample Rate (Optional): Leave both on "Original" to mirror the source, or pick mono or a specific sample rate to match your project. The Trim control can clip the output to a chosen start and duration.
- Convert and Download: Click "Convert" and save your AIFC. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours. No sign-up, no watermark.
Frequently Asked Questions
Will converting OGV to AIFC improve the audio quality?
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.
Does the AIFC file keep the video from the OGV?
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.
Why is the AIFC file so much larger than the OGV?
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.
What is the difference between AIFC and plain AIFF?
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.
Which programs can open an AIFC file?
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.
Should I choose AIFC or WAV for the extracted audio?
Both store the same uncompressed PCM, so there is no fidelity difference — the choice is ecosystem. AIFC (AIFF-C) uses big-endian byte order and is the native fit for macOS, Logic Pro, and GarageBand. WAV uses the little-endian RIFF layout and is the safer interchange format on Windows and across most cross-platform tools. If your workflow lives on a Mac, stay with AIFC; otherwise OGV to WAV is the more portable equivalent.
What sample rate and bit depth does the AIFC output use?
By default the tool writes 16-bit PCM and preserves the source track's sample rate when Audio Sample Rate is left on "Original." You can select 24-bit PCM under the Audio Codec option for more headroom in a mastering chain, or pick a specific sample rate to resample. Bear in mind the source Vorbis is lossy, so 24-bit and higher sample rates make a larger file without recovering any detail the original never stored.
Can I extract only part of the OGV's audio?
Yes. Open the Trim control and set a start point and duration, and only that section of the soundtrack is written to the AIFC — handy for pulling a single line, a music cue, or a short clip out of a longer recording without editing afterward. Leaving Trim untouched exports the full-length audio.
Are my files kept private during conversion?
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.
