MP3 to AIFF. Apple-native for Logic, GarageBand, Final Cut.
AIFF is what Logic and GarageBand prefer when you drag music in from outside a project. WAV works too, but AIFF is the older native format and some Apple Loops / Final Cut workflows behave better with it. Drop your MP3, get a 16-bit AIFF back. Same audio, different container.

WAV, M4A, FLAC, OGG also welcome. Batch supported.
When you need AIFF instead of WAV
- Logic Pro — accepts both, prefers AIFF for in-project bouncing and Apple Loops. WAV works fine for drag-imports.
- GarageBand — same as Logic. AIFF is the native bounce format.
- Final Cut Pro — handles both, but FCP-generated audio assets are AIFF.
- Apple Loops authoring — Apple Loops Utility expects AIFF input for tagging metadata.
- Older Mac DAW projects — anything pre-Logic-9 era is more comfortable with AIFF.
What AIFF gives you that MP3 doesn't
- Lossless containment — no further generational loss if you edit and re-bounce.
- Sample-accurate editing — MP3 has frame boundaries that complicate exact cuts.
- Better DAW timeline behavior — uncompressed audio doesn't need decode-on-play.
- Compatibility with Apple's loop/region time-stretching engines.
What it doesn't give you: better audio quality than the source MP3. Lossy compression is one-way.
FAQ
How much bigger will the AIFF be?
Roughly 10× the MP3 size — same scale as WAV. A 5 MB MP3 becomes a ~50 MB AIFF.
Why is AIFF bigger if it doesn't sound better?
It's uncompressed. MP3 throws away audio data to be small. Converting to AIFF just unpacks the (now-permanently-degraded) audio into an uncompressed container.
What about 24-bit AIFF?
We output 16-bit, which is the standard for music delivery. 24-bit is useful during mixing but unnecessary for finished tracks. For 24-bit specifically, contact us — we'll add the option.
Can I convert AIFF back to MP3?
Yes — use our universal converter or WAV → MP3 page (it accepts AIFF too).
Will GarageBand on iPad / iOS read this AIFF?
Yes. iOS GarageBand reads AIFF from Files. Drag it from the Files app into the Tracks view.
Does it upload?
No. Conversion runs in your browser.
