About AIFF to MP3
What is AIFF?
AIFF (Audio Interchange File Format) was developed by Apple in 1988 as the Mac equivalent of WAV. Like WAV, AIFF stores uncompressed PCM audio at CD quality or higher. It's the native format for Logic Pro, GarageBand, and many Mac-based audio workflows. AIFF files are the same massive size as WAV — about 10MB per minute of CD-quality stereo audio.
Why convert to MP3?
AIFF's uncompressed quality comes at a steep storage cost. Convert to MP3 when sharing music or audio recordings via email, uploading to streaming platforms, loading onto portable devices, or any situation where universal playback and small file sizes matter more than studio-quality fidelity.
What to expect from the conversion
AIFF to MP3 is a lossy compression process, reducing file sizes by roughly 90%. At 256-320kbps, the quality loss is inaudible on consumer equipment. At 128kbps, it's adequate for speech. Audio metadata and ID3 tags are created from AIFF's metadata fields. Keep your original AIFF files as lossless masters.
How FluidConvert handles it
We decode your AIFF PCM audio and compress it using the LAME encoder — the industry standard for MP3 encoding — producing optimal quality at your chosen bitrate.
Common reasons to convert AIFF to MP3
- Converting Logic Pro or GarageBand AIFF bounces to MP3 for client distribution
- Compressing AIFF podcast recordings for upload to Apple Podcasts or Spotify
- Making AIFF music files portable for phone storage and Bluetooth playback
- Creating MP3 preview copies of AIFF master recordings for band members to review
Frequently Asked Questions
Is AIFF the same quality as WAV?
Yes. Both AIFF and WAV store uncompressed PCM audio at identical quality. They're essentially the same format with different headers — AIFF from Apple, WAV from Microsoft. Converting either to MP3 produces identical results.
Will my Logic Pro project's AIFF bounces sound good as MP3?
At 256kbps or higher, the difference between your AIFF bounce and the MP3 is virtually inaudible. For client review copies and streaming distribution, 256kbps MP3 is the industry standard.
Can GarageBand or Logic Pro export directly to MP3?
GarageBand can export to MP3 directly. Logic Pro can export to MP3 via the Bounce function. However, if you have existing AIFF files from previous projects, converting them online is faster than re-opening each project to re-export.
