Why Extract Audio from MPG as AIFF?

MPG files were the standard video format for DVDs and early digital video. When you need the audio track from these videos, AIFF delivers it without compression. Unlike MP3 which discards audio data, AIFF files preserve every bit of the original sound.

This matters when you're editing audio professionally. Compressed formats degrade further with each edit. AIFF maintains quality through multiple editing passes, making it the format of choice for Mac-based audio workstations like GarageBand and Logic Pro.

How to Convert MPG to AIFF

  1. Upload your MPG file - Drag and drop or click to select your video
  2. Select AIFF as output - Choose AIFF for uncompressed audio quality
  3. Download your audio - Get your AIFF file ready for editing

The entire process runs in your browser. No software to install, no accounts to create. Upload, convert, download.

MPG vs AIFF: What Changes

MPG is a video container that holds both video and audio streams. The audio inside is typically MPEG Audio Layer II or occasionally AC3. When converting to AIFF, we extract and decode the audio stream into uncompressed PCM format.

  • Source format - MPG video (MPEG-1 or MPEG-2 container)
  • Audio codec - Usually MPEG Audio Layer II at 224-384 kbps
  • Output format - AIFF (uncompressed PCM audio)
  • File size - AIFF files are larger because audio is uncompressed

In our testing, a 5-minute MPG video with stereo audio produces an AIFF file around 50MB at CD quality (44.1kHz, 16-bit).

When to Use AIFF Output

Audio Editing Projects

If you're bringing the audio into a DAW (Digital Audio Workstation), AIFF is the right choice. Software like Logic Pro, GarageBand, and Pro Tools work natively with AIFF files.

Mac-Based Workflows

AIFF was developed by Apple and has deep integration with macOS. If you're working on a Mac, AIFF often loads faster and integrates more smoothly than other formats.

Archiving Audio

When preserving audio from old MPG files, AIFF ensures no quality loss. You can always convert to smaller formats later, but you can't recover quality once it's compressed.

When AIFF Isn't the Best Choice

AIFF files are large. For a music library or casual listening, MPG to MP3 gives you files 10x smaller that sound nearly identical to most listeners. If you're not editing the audio or need to save storage space, consider compressed alternatives.

For cross-platform compatibility with editing software, MPG to WAV is equally lossless and works on Windows, Linux, and Mac alike.

Works on Any Device

Our converter runs entirely in your browser:

  • Windows, Mac, Linux, Chromebook
  • Chrome, Firefox, Safari, Edge
  • iPhone, iPad, Android devices

No plugins required. No software to download. Just upload your MPG and get AIFF.

Pro Tip

If your MPG comes from a DVD, the audio is likely AC3 (Dolby Digital) surround sound. AIFF can preserve stereo but will downmix multi-channel audio. For true surround preservation, extract to multi-channel formats separately.

Common Mistake

Choosing AIFF for simple playback or music libraries. AIFF files are 10x larger than MP3 with no audible difference for casual listening. Reserve AIFF for editing projects where you need lossless quality.

Best For

Mac users who need to edit audio from old MPG recordings in GarageBand, Logic Pro, or other Apple audio software. AIFF integrates seamlessly with the macOS ecosystem.

Not Recommended

If you just want to listen to the audio or share it online. Use MP3 for portability and smaller file sizes. AIFF is overkill for playback-only purposes.

Frequently Asked Questions

MPG is a video file format based on MPEG-1 or MPEG-2 standards. It was widely used for DVDs and early digital video. MPG files contain both video and audio streams in a single container.

AIFF (Audio Interchange File Format) is an uncompressed audio format developed by Apple. It stores audio in raw PCM format without any compression, preserving full audio quality. AIFF is commonly used in professional audio production on Mac systems.

No. Converting cannot add quality that wasn't in the original MPG audio track. However, AIFF preserves the extracted audio without further compression, making it ideal for editing where additional processing could degrade compressed formats.

AIFF stores uncompressed audio data while MP3 uses lossy compression that discards inaudible frequencies. A typical 3-minute song is about 30MB in AIFF versus 3MB in MP3. The tradeoff is perfect quality retention in AIFF.

Yes. Our converter works in Safari on iOS devices. Upload your MPG file through the browser and download the converted AIFF directly to your device.

Both are uncompressed and equal in audio quality. AIFF has better metadata support and integrates more smoothly with Mac software like Logic Pro. WAV is more universal across platforms. Choose based on your operating system and software preferences.

Conversion typically takes a few seconds for short videos. Longer MPG files may take up to a minute depending on file size and your internet connection speed for upload.

No. AIFF is an audio-only format. The conversion extracts just the audio track from your MPG video. The video portion is discarded.

The output AIFF matches the sample rate of the original MPG audio track, typically 44.1kHz or 48kHz. We preserve the original audio specifications without resampling unless necessary.

Yes. Upload multiple MPG files at once to convert them all to AIFF in a single batch. Each file is processed and available for individual download.
