MPEG to AIFF Converter
Processing entirely on your device — large files may take a moment.
AIFF imports cleanly into Logic Pro and older Mac audio tooling. If your files are still in MPEG format, this page is the shortcut: MPEG is the full-name spelling of the MPG program stream — identical multiplexed video+audio, four-letter vs three-letter extension.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.
How MPEG compares to AIFF
| MPEG | AIFF | |
|---|---|---|
| Compression | MPEG-1 / MPEG-2 | Uncompressed PCM |
| Quality | Standard definition | Bit-exact |
| Compatibility | Universal decode | Mac-first |
| Best for | Legacy disc and capture video | Mac recording and production |

About the MPEG format
MPG (MPEG program stream) usually means MPEG-1 or MPEG-2 video — the codecs of VCD, SVCD and DVD, and of countless home video captures in the 1990s and 2000s. MPEG-1 tops out around VHS-grade 352×288; MPEG-2 delivers proper standard definition and still runs inside broadcast and DVD infrastructure.
Playback compatibility is its superpower: MPEG-1/2 decode paths exist in every player and hardware made this century. Quality-to-bitrate efficiency, however, is a generation behind H.264 — converting old MPG files to MP4 typically halves their size.
+Strengths
- ✓Decodes on essentially every player and device
- ✓Simple, battle-tested standard
!Limitations
- −Inefficient codecs by modern standards
- −MPEG-1 is VHS-grade at best
About the AIFF format
AIFF is Apple's counterpart to WAV: uncompressed PCM in an IFF container, born with the classic Mac in 1988. It stores the same bit-perfect audio as WAV but carries metadata far better — iTunes-era tags, cover art and loop points all fit natively, which made it the default of Logic Pro and Mac-based audio production.
Functionally the WAV-versus-AIFF choice is platform history: same quality, same sizes, AIFF friendlier on Mac, WAV friendlier everywhere else. Converting between them is a lossless retagging exercise, nothing more.
+Strengths
- ✓Bit-perfect uncompressed audio
- ✓Better metadata support than WAV
- ✓Native to macOS and Logic Pro
!Limitations
- −Same bulk as WAV (~10 MB/minute)
- −Windows tooling historically prefers WAV
Why convert MPEG to AIFF?
Think of it as moving your file to the container that fits the job. Inefficient codecs by modern standards AIFF works differently: Bit-perfect uncompressed audio If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this MPEG to AIFF converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for MPEG to AIFF?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Why is video conversion slower than image conversion?
Every frame has to be decoded and re-encoded. This site runs that work on your own CPU via WebAssembly — nothing is uploaded, but a multi-minute video reasonably takes a few minutes. Images, by comparison, are single-frame jobs.
Does converting MPEG to AIFF re-encode my video?
Yes. The video is decoded and re-encoded with the settings chosen by the quality slider, which is what allows the format and size to change. For an archival copy, keep higher quality; for sharing, lower quality gives a much smaller file.
