Convert AIFF to WAV — Free Online Converter

AIFF and WAV are sibling formats — both store raw uncompressed PCM audio with nearly identical quality. AIFF uses big-endian byte order and originates from Apple (1988), while WAV uses little-endian byte order and comes from Microsoft/IBM (1991). Converting AIFF to WAV is a byte-order swap and header rewrite — the audio samples are mathematically identical. This conversion provides universal compatibility since WAV is supported by every audio application on every platform.

While AIFF is native to macOS, WAV is the universal uncompressed format. Windows DAWs (FL Studio, Ableton on PC, Audacity), broadcast equipment, scientific instruments, and game engines often expect WAV specifically. Some CD mastering software requires WAV input. Converting AIFF to WAV eliminates any compatibility friction when moving between Apple and non-Apple environments.
