MPEG-2 to AIFF Converter

MPEG-2 to AIF Converter

This tool extracts the audio track from an MPEG-2 file and writes it to AIF (Apple's Audio Interchange File Format). MPEG-2 (.mpeg2 / .mpg) is a video standard — a program stream usually carries an MPEG-2 video track plus an audio track in MP2, MP3, or AC-3 — and this conversion keeps only the sound, discarding the picture. AIF is uncompressed PCM, the Mac-native sibling of WAV, so the result is a large, lossless-container audio file ready for Logic Pro, GarageBand, or any Apple audio workflow.

How to Convert MPEG-2 to AIF

1. Upload Your MPEG-2 File: Drag and drop your .mpeg2 or .mpg file, or click "Add Files" to browse. You can queue several files to extract their audio with the same settings.
2. Set the Audio Channel: Leave it on Original to keep the source layout, or pick Mono to halve the file size when stereo separation does not matter.
3. Set the Audio Sample Rate: Keep Original to preserve the source rate, or choose a standard rate such as 44100 Hz or 48000 Hz to match your project; use Trim if you only need a clip.
4. Convert and Download: Click Convert and save your AIF file. Files upload over an encrypted connection, are processed on our servers, and are deleted automatically after a few hours. No sign-up, no watermark.

Frequently Asked Questions

Is AIF the same as AIFF?

Yes. .aif and .aiff are interchangeable extensions for the same Audio Interchange File Format. The shorter .aif dates from older Macintosh systems that limited extensions to three characters; modern macOS and audio apps treat both identically. This tool writes standard uncompressed PCM, which both extensions accept.

Will converting to AIF improve the audio quality?

No. The audio inside an MPEG-2 program stream is usually MP2 or AC-3, which are lossy — quality already lost during the original encoding cannot be recovered. Writing that audio to AIF simply stops adding loss and stores the decoded samples as uncompressed PCM. You get a faithful, lossless container of the existing audio, not a higher-fidelity master.

Why is the AIF file so much larger than the source?

AIF is uncompressed PCM, so it has no size advantage over WAV — both store raw samples at roughly 10 MB per minute for 44.1 kHz / 16-bit stereo. The source MPEG-2 audio was compressed (MP2/AC-3), so expanding it to PCM naturally produces a much bigger file. If you need a small, portable file instead, convert to MP3; if you want a Windows-friendly lossless container, use WAV.

What if my MPEG-2 file has no audio?

Some MPEG-2 files are video-only elementary streams (often .m2v) with no audio track to extract. A typical .mpeg2 or .mpg program stream from a DVD or broadcast capture does contain audio, but if your source is video-only there is nothing to write to AIF. In that case you would need a file that actually carries an audio track.

Does the output keep any video?

No. This is an audio-extraction conversion — the MPEG-2 video track is discarded and only the audio is written to AIF. If you want to keep the video, convert to a video format instead of an audio one.

Should I choose AIF, WAV, or MP3?

Pick AIF for Apple audio software such as Logic Pro and GarageBand, where it is the native lossless container. Choose WAV for the same uncompressed quality with broader Windows and cross-platform support, or MP3 when you want a small file for sharing, phones, or general playback. AIF and WAV are functionally equivalent in quality; MP3 trades some fidelity for a much smaller size.

Can I extract just a clip instead of the whole track?

Yes. Expand the options and use Trim to set a start time and duration, so only that segment of the MPEG-2 audio is written to AIF. This is handy when you only need a few seconds — for example, lifting a single line or sound effect from a longer recording — and keeps the uncompressed file from growing unnecessarily large.
