AIFF files sound great but are massive. The MyPDF AIFF to MP3 converter compresses your Apple lossless audio files into compact MP3 format — reducing file size by up to 90% with minimal quality loss.
How to Convert AIFF to MP3
- Upload your AIFF file(s).
- Choose the MP3 bitrate (128-320 kbps).
- Download the compressed MP3 instantly.
AIFF vs. MP3 Comparison
| Feature | AIFF | MP3 |
|---|---|---|
| Quality | Lossless | Lossy |
| File size (per min) | ~10 MB | ~1-2.4 MB |
| Compatibility | macOS native | Universal |
| Editing | Ideal | Adequate |
| Streaming | Impractical | Standard |
Practical Tips
- Use 256-320 kbps for music you care about — at these bitrates, MP3 is virtually indistinguishable from the AIFF original.
- Use 128-192 kbps for podcasts and speech — spoken content doesn't benefit from higher bitrates.
- Keep AIFF originals as your master archive and use MP3 copies for portable devices and sharing.
Is AIFF the same as WAV?
Both are uncompressed lossless formats. AIFF is Apple's standard (from macOS/Logic Pro), while WAV is the Windows/PC equivalent. They sound identical at the same specs.
Will I lose quality?
MP3 is lossy, so some high-frequency detail is removed. At 256+ kbps, the difference is inaudible to most listeners in blind tests.
