Convert uncompressed Apple AIFF studio audio recordings into universal high-bitrate MP3 audio files with up to 90% file size savings.
AIFF (Audio Interchange File Format) is Apple's uncompressed studio recording standard, equivalent to Windows WAV. While AIFF preserves flawless master-grade acoustic quality, an uncompressed 4-minute track takes up over 40MB to 60MB of storage. Converting AIFF to MP3 reduces the file footprint by 85% to 90% while maintaining crisp high-frequency reproduction and dynamic stereo separation, making your Logic Pro and Mac audio tracks ready for easy sharing, emailing, and mobile listening.

AIFF is an uncompressed, lossless audio file format standard developed by Apple Computer in 1988 based on Electronic Arts' Interchange File Format (IFF). Like WAV on Windows, AIFF stores raw uncompressed pulse-code modulation (PCM) audio samples, making it a foundation standard for Apple Mac studio recording, professional music engineering, and broadcast audio. AIFF preserves 100% of the acoustic fidelity with zero compression artifacts. AIFF files open natively on macOS and iOS via Apple Music, QuickTime, and across professional DAWs like Logic Pro, Pro Tools, and Audacity.
MP3 is the world's most recognized and universally supported digital audio format. Developed in Germany by the Fraunhofer Institute alongside the Moving Picture Experts Group (MPEG) and standardized in 1993, MP3 uses sophisticated psychoacoustic perceptual coding to discard sound frequencies beyond the threshold of human hearing. This compression reduces raw audio data by roughly 75% to 90% without severe perceptual distortion. MP3 remains the global standard for music distribution, podcasts, and digital broadcasting. You can open and play MP3 files natively on Microsoft Windows (Windows Media Player, Groove Music), Apple macOS and iOS (Apple Music, QuickTime), Google Android, Linux (VLC, Audacity), smart TVs, and vehicle infotainment stereos.
| Feature | AIFF (Studio Uncompressed) | MP3 (Universal Compressed) |
|---|---|---|
| Audio Type | Uncompressed Linear PCM | Perceptual Psychoacoustic Lossy |
| Typical File Size | 40MB – 60MB per song | 4MB – 9MB per song |
| Compatibility | Apple macOS, iOS, Professional DAWs | 100% of all digital devices worldwide |
AIFF is uncompressed while MP3 uses lossy compression. Choosing 320kbps or 256kbps preserves exceptional acoustic detail that is virtually indistinguishable to the human ear.
You can upload AIFF master files up to 500MB.
Yes, all AIFF and AIF audio exports from Logic Pro, Pro Tools, GarageBand, and Audacity are supported.
