Need help?MPEG to AIFC Converter
An .mpeg file is an MPEG-1/-2 video clip whose soundtrack is almost always MP2 (MPEG-1 Audio Layer II), a lossy codec. This tool pulls that soundtrack out and writes it as AIFC (AIFF-C), the Apple audio container, dropping the video entirely. One thing to know up front despite the format name: this converter writes the audio as uncompressed PCM inside the AIFC wrapper, so the output is larger than the source audio, not smaller — and decoding lossy MP2 cannot add back fidelity that was already removed.
MPEG (source) Format at a Glance
| Property | Value |
|---|---|
| Standard | MPEG-1, ISO/IEC 11172 (1993); MPEG-2 ISO/IEC 13818 |
| Released | 1993 (MPEG-1) |
| What it holds | Video + audio multiplexed in one program stream |
| Typical audio codec | MP2 (MPEG-1 Audio Layer II), lossy |
| Typical audio bitrate | 192-384 kbps for near-CD stereo (Layer II) |
| Common origin | Video CD, DVD rips, old TV/PVR captures |
| Native playback | VLC, MPC-HC, most DVD-era and desktop players |
AIFC (output here) Format at a Glance
| Property | Value |
|---|---|
| Format | AIFF-C, form type AIFC, Apple |
| Released | July 1991 (AIFF itself: 1988) |
| What it holds | Audio only — the MPEG video is discarded |
| Audio written here | Uncompressed PCM, 16-bit, big-endian (compression type NONE) |
| "Compressed"? | No. AIFF-C is a container that can hold compressed audio, but this tool writes raw PCM |
| Equivalent bitrate | ~1411 kbps for 16-bit/44.1 kHz stereo |
| Native playback | macOS, QuickTime, Logic Pro; Audacity and VLC elsewhere |
| Best for | Legacy Apple software or samplers that specifically want the .aifc form |
How to Convert MPEG to AIFC
- Upload Your MPEG File: Drag and drop your
.mpeg(or.mpg) onto the page, or click "+ Add Files" to browse. Queue several clips to convert them in one batch with the same settings. - Set the Audio Sample Rate: Open Advanced Options and leave Audio Sample Rate on "Original" for a true 1:1 transfer of the source audio, or choose a specific rate only if a target sampler or device requires one.
- Set the Audio Channel or Trim (Optional): Leave Audio Channel on "Original" to keep the source layout, or force Mono/Stereo. Set Trim (default "Unchanged") to export only a start-and-duration window instead of the whole soundtrack.
- Convert and Download: Click "Convert" and download your AIFC file. No sign-up, no watermark.
Frequently Asked Questions
Does converting MPEG to AIFC keep the video?
No. This is an audio-extraction conversion: it reads the audio stream out of the MPEG program stream, writes it to an AIFC file, and discards the picture entirely. The output has no video. If you need to keep the video and only change the container, that is a video-to-video conversion, not this one.
Is the AIFC file actually compressed, since the "C" stands for "Compressed"?
Not as written here. The AIFF-C specification (Apple, July 1991) defines a container that can carry compressed audio — legacy codecs like MACE, A-law, or μ-law — but it equally holds uncompressed PCM, and that is exactly what this converter writes: compression type NONE, 16-bit big-endian. Many file-type sites flatten "AIFF-C" to "compressed," but the "C" describes a capability of the wrapper, not the contents of your file.
Will the AIFC sound better than the audio in my MPEG?
No. An MPEG soundtrack is almost always MP2, a lossy codec that permanently dropped some detail when the file was first encoded. Decoding that MP2 to uncompressed PCM and wrapping it in AIFC stores the samples your player already produces — it cannot reconstruct what was removed. The AIFC sounds the same as the MPEG's audio, just in a larger, uncompressed container.
Why is the AIFC much larger than my MPEG's audio?
Because the AIFC here is uncompressed. MP2 inside an MPEG typically runs 192-384 kbps; the AIFC writes every sample in full at 16-bit, equivalent to roughly 1411 kbps for CD-quality stereo. In our testing, a one-minute MPEG with a 224 kbps MP2 track produced an AIFC of about 10 MB — far larger than the source audio, precisely because it is uncompressed rather than worse-sounding.
What opens an AIFC file once I have it?
AIFC plays natively on macOS, in QuickTime, and in pro tools like Logic Pro. On other systems, Audacity and VLC open it reliably, and most FFmpeg-based players handle the uncompressed NONE variant this tool produces. Some older Windows media players handle AIFF-C poorly; if you need the widest compatibility instead, MPEG to WAV writes the same uncompressed PCM in the more universally accepted WAV container.
When should I pick AIFC instead of WAV, AIFF, or MP3?
Pick AIFC only when a specific tool demands the .aifc form — for example an older Apple authoring app or a sampler that imported AIFF-C natively. For an uncompressed Apple file with broader support, MPEG to AIFF is the more standard sibling; for editing on any platform, WAV is the safest uncompressed target; and for a small, universally playable file, MPEG to MP3 is the better choice. AIFC is the niche pick, not the default.
What happens if my MPEG has no audio track?
The output will be empty or silent. Some MPEG files are video-only, or carry an audio stream that cannot be decoded. Confirm the clip actually plays sound first; if it does and the result is still silent, the audio stream may be damaged.
How are my files handled, and how long do you keep them?
Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared or made public.
