Need help?3GPP to AIFC Converter
This tool extracts the audio track from a 3GPP video file and re-encodes it into AIFC (AIFF-C), Apple's Audio Interchange container. .3gpp is the same mobile-phone video container as .3gp — both are defined by the 3rd Generation Partnership Project (3GPP) and behave identically. The video stream is discarded; only the sound is kept, wrapped into an .aifc file that QuickTime, Logic, and other macOS audio apps open natively.
One honest caveat up front: 3GPP audio is almost always AMR or AAC, which are lossy codecs. Re-encoding that audio to uncompressed PCM inside AIFC does not restore detail that was already discarded — it produces a larger, edit-friendly file in an Apple-native wrapper, not a higher-fidelity master.
3GPP Format at a Glance
| Property | Value |
|---|---|
| Defined by | 3rd Generation Partnership Project (3GPP) |
| Container basis | MPEG-4 Part 12 (ISO base media) |
| Extension | .3gp / .3gpp (equivalent) |
| Typical audio codec | AMR-NB, AMR-WB, or AAC (all lossy) |
| Typical video codec | H.263, MPEG-4 Part 2, or H.264 |
| Built for | GSM mobile phones — small camera clips, voice notes |
| Audio in output | Discarded video; audio track extracted only |
AIFC (AIFF-C) Format at a Glance
| Property | Value |
|---|---|
| Developed by | Apple Inc. |
| Released | AIFF in 1988; the AIFF-C (AIFC) revision in July 1991 |
| Preferred extension | .aifc (players also accept .aif / .aiff) |
| Payload | Can wrap uncompressed PCM or a compressed codec (A-law, mu-law, MACE, IMA ADPCM) |
| This tool's default | 16-bit PCM, big-endian (uncompressed) |
| Best for | macOS / Logic Pro / QuickTime workflows needing an AIFF-family file |
| Note | AIFC with PCM is uncompressed; A-law/mu-law payloads are themselves lossy |
How to Convert 3GPP to AIFC
- Upload Your 3GPP File: Drag and drop your
.3gppor.3gpfile onto the page, or click "+ Add Files" to browse. Several clips can be queued and converted with the same settings. - Confirm the Audio Codec: AIFC output defaults to 16-bit PCM (uncompressed). Open "Show All Options" to switch the Audio Codec to PCM A-law or mu-law if you want a smaller telephony-style file.
- Adjust Audio Channel, Sample Rate, or Trim: Optionally set Audio Channel (mono/stereo) and Audio Sample Rate, or use Trim to keep only part of the clip — leave them on "Original" to copy the source.
- Convert and Download: Click "Convert" and save the
.aifcfile. No sign-up, no watermark.
Frequently Asked Questions
Does converting 3GPP to AIFC improve the audio quality?
No. The audio inside a 3GPP file is already lossy (usually AMR or AAC), so encoding it to uncompressed PCM in AIFC cannot recover detail that was lost during the original recording. You get a larger, uncompressed file that is easier to edit and Apple-native — not a higher-fidelity one.
What happens to the video in my 3GPP file?
It is dropped. AIFC is an audio-only container, so this conversion pulls out the sound track and discards the picture. If you need to keep the video, convert to a video format instead.
Is .3gpp different from .3gp?
No — they are the same container, both defined by 3GPP and based on MPEG-4 Part 12. Some phones and apps write the longer .3gpp extension, but the file contents and supported codecs are identical to .3gp.
What is the difference between AIFC and AIFF?
AIFF (1988) stores plain uncompressed PCM audio. AIFC (AIFF-C, July 1991) is a revision of the same container that can also hold compressed payloads such as A-law, mu-law, or MACE. By default this tool writes uncompressed 16-bit PCM into the AIFC wrapper, so the result is effectively AIFF-equivalent audio with the .aifc extension. If you specifically want the .aiff extension, use the 3GPP to AIFF converter.
What opens an AIFC file?
On macOS, QuickTime Player, Music/iTunes, Logic Pro, and GarageBand open AIFC natively. On Windows, VLC Media Player handles it; many lightweight players do not, especially when a non-PCM codec is used inside. That limited portability is the main reason people convert AIFC files onward.
Should I convert to AIFC or to MP3 instead?
Choose AIFC only if your workflow is Apple/macOS audio editing. For a small, universally portable file — email, messaging, web — an MP3 is far smaller and plays everywhere. In that case use 3GPP to MP3, or 3GP to MP3 if your file carries the .3gp extension.
How big will the AIFC file be compared to the 3GPP?
Usually much larger. The audio inside a 3GPP is a compact lossy codec — AMR voice can be only a few kilobytes per second — while the default AIFC output is uncompressed 16-bit PCM at roughly 10 MB per minute for 44.1 kHz stereo. Re-encoding lossy audio to PCM inflates the size without adding fidelity, because the detail the original codec discarded is already gone. For an Apple-native but smaller file, choose the PCM A-law or mu-law codec, or convert to 3GPP to MP3 instead.
Are my files private during conversion?
Yes. Files are 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. The practical limit on a large upload is your connection speed, not a device memory cap.
