MPEG1 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 MPEG1 format, this page is the shortcut: MPEG1 names the first-generation MPEG codec family (VCD era) — the same program stream data MPG files carry.
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 MPEG1 compares to AIFF
| MPEG1 | 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 MPEG1 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 MPEG1 to AIFF?
Converting makes sense where the strengths of AIFF meet what MPEG1 cannot give you. Bit-perfect uncompressed audio Meanwhile Inefficient codecs by modern standards One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this MPEG1 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 MPEG1 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.
Does converting MPEG1 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.
Will the audio track be kept?
Yes. The audio is carried over and re-encoded to the standard audio codec of AIFF, staying in sync with the video. If your MPEG1 file has multiple audio tracks, the first one is used.
