Convert WMA to AIFF — Free Online Converter

WMA is Microsoft's lossy audio codec, delivering compressed audio at typical bitrates of 64-320 kbps within the ASF container. AIFF (Audio Interchange File Format) is Apple's uncompressed PCM audio container, storing raw audio samples at full fidelity. AIFF was introduced by Apple in 1988 and remains the native uncompressed format for macOS audio workflows.

Converting WMA to AIFF decodes the compressed WMA audio back to raw PCM samples and stores them in the AIFF container. This prepares the audio for professional editing in Logic Pro, GarageBand, or Pro Tools, where uncompressed input prevents cumulative generation loss during processing.

Professional audio editing requires uncompressed source files. When you apply effects, normalize levels, or mix audio in a DAW, each operation on a compressed file risks compounding artifacts. AIFF provides the uncompressed PCM baseline that professional software expects. Converting WMA to AIFF is necessary when WMA recordings must enter an Apple-based production pipeline.

AIFF is also the expected delivery format for some mastering facilities and broadcast systems on macOS. If a client sends you WMA files and your studio runs Logic Pro, converting to AIFF ensures smooth import and editing.
