- AIFF files are uncompressed, so converting to MP3 at 320 kbps retains excellent quality at a fraction of the file size.
- Use 192 kbps or higher for music to maintain good audio fidelity.
- AIFF is common in macOS and Logic Pro workflows; MP3 makes files easier to share cross-platform.
- Batch convert entire folders of AIFF files for efficient workflow.
- Converts uncompressed AIFF audio to compact MP3 format
- Multiple bitrate options from 128 to 320 kbps
- Preserves metadata tags from AIFF during conversion
- Supports both .aiff and .aif file extensions
- Fast encoding powered by LAME MP3 encoder
- Sharing Logic Pro exports as MP3 files for client review
- Reducing large AIFF music files for portable device storage
- Converting AIFF samples to MP3 for web embedding

AIFF is Apple's uncompressed audio format, commonly used in macOS audio production. It offers the same quality as WAV but uses a different container format.
An MP3 at 320 kbps is roughly 5x smaller than the equivalent AIFF. At 128 kbps, it can be 10-15x smaller.
Yes, MP3 is a lossy format. However, at 256-320 kbps, the quality loss is minimal and typically imperceptible for most listening scenarios.
