M4A 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 M4A format, this page is the shortcut: M4A is Apple’s audio container (AAC), the default for iTunes, Voice Memos and iPhone recordings.
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 M4A compares to AIFF

| Quality | Strong at 128–256 kbps | Bit-exact |
| Compatibility | Apple-first, modern platforms | Mac-first |
| Best for | Music libraries and voice memos | Mac recording and production |

About the M4A format
M4A is MPEG-4 audio: AAC (or ALAC) inside the MP4 container, minus the video. It became the iTunes Store's format in 2003 and never left — Apple Music downloads, voice memos and most phone recordings are M4A. At the same bitrate, AAC sounds distinctly better than MP3, which is why 128 kbps M4A competes with 192 kbps MP3.
Support is excellent across Apple devices, modern Android, Windows and every streaming SDK. The one historical caveat: iTunes Store music bought before 2009 carried FairPlay DRM; everything since (and everything you record yourself) is DRM-free.
+ Strengths
- ✓Better quality than MP3 at the same bitrate
- ✓First-class on Apple and modern platforms
- ✓ALAC variant covers lossless needs
! Limitations
- −Very old feature phones and players miss it
- −Pre-2009 store purchases may carry DRM
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 M4A to AIFF?
Converting makes sense where the strengths of AIFF meet what M4A cannot give you. Bit-perfect uncompressed audio Meanwhile Very old feature phones and players miss it One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this M4A 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 M4A 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.
Are tags like title and artist preserved?
Tag handling varies between target formats and this conversion focuses on the audio itself. For archival copies where tags matter, keep the original file; the converted copy is for playback and sharing.
Can I convert a whole folder of M4A files?
You can select many files at once and they are processed in a single batch. Output files land in one ZIP download when there is more than one result.
