MP3: lossy. Lossy targets trade size for speed — preview when it matters.
Wide compatibility
AIFF is commonly used for Logic/GarageBand style PCM exports and Mac audio archives.
AIFF vs MP3
A quick side-by-side before you convert — deeper comparison lives on the full guide.
| Feature | AIFF | MP3 |
|---|---|---|
| Kind | audio | lossy audio |
| Compression | usually uncompressed PCM | lossy |
| Lossy / lossless | Lossless / not lossy | Typically lossy |
| Transparency | Not supported / N/A | Not supported / N/A |
| Best for | Logic/GarageBand style PCM exports; Mac audio archives | Music downloads; Podcast RSS enclosures |
| Typical size | Large — similar to WAV for the same sample rate/bit depth | ~1 MB per minute at 128 kbps |
| Browser / web support | Spotty — convert to WAV/MP3 for web playback | Universal |
| Compatibility | Native on classic Mac audio tooling; Windows shops usually prefer WAV — convert when exchanging PCM across platforms | Plays on essentially every phone, car stereo, smart speaker, and browser — still the safest audio delivery extension |

Tip
Keep an original copy of your AIFF file if you may need to reconvert later.
Does AIFF to MP3 reduce quality?
MP3 is typically lossy (lossy). Use a higher bitrate when fidelity matters, and keep the AIFF master for archival.
MP3 format guide →Should I keep the original AIFF?
Yes when you may need to re-encode later. AIFF: AIFF is WAV’s Apple-leaning sibling for uncompressed PCM. Great in Logic and older Mac audio trees; convert to WAV/FLAC/MP3 depending on whether you need exchange, archive, or delivery.

Frequently Asked Questions
More on quality loss: conversion quality guides · problem-solution guides
Does AIFF to MP3 lose quality?
It can. MP3 is typically lossy, so encoding may discard detail for smaller files. Use higher quality/bitrate settings when fidelity matters, and keep the AIFF master.
Does converting AIFF to MP3 reduce quality?
Often yes at default lossy settings. Raise quality/bitrate for delivery, or stay on a lossless format when you still need a master.
Can you recover quality after converting?
Not from a lossy output alone. Return to the original master (or a better source). Converting to a lossless format does not resurrect discarded detail.
What is generational loss?
Damage that stacks when you decode and lossy-encode the same file over and over (for example JPG→edit→JPG). Edit from masters and export delivery formats once.
Where can I learn more about conversion quality?
Browse Format Convertly’s Quality guides for topics like whether conversion reduces quality, JPG↔PNG myths, WebP/MP3/MP4 tradeoffs, recovery limits, and generational loss — each links to the right converter.
What is a AIFF file?
AIFF is Audio Interchange File Format — Apple’s classic uncompressed audio format. AIFF is WAV’s Apple-leaning sibling for uncompressed PCM. Great in Logic and older Mac audio trees; convert to WAV/FLAC/MP3 depending on whether you need exchange, archive, or delivery.
Is AIFF lossy or lossless?
AIFF is typically lossless or non-destructive in common use (usually uncompressed PCM).
What is a MP3 file?
MP3 is a lossy audio format that remains the most compatible music and podcast compression choice. MP3 plays everywhere: cars, phones, smart speakers. Quality is strong at sensible bitrates, but AAC/Opus often win efficiency. Keep WAV/FLAC masters and export MP3 for distribution.
