Convert WAV to AIFF Online
Massive file sizes (10 MB per minute at CD quality) make it impractical for streaming or casual sharing. Converting to AIFF gives you a key advantage: stores uncompressed pcm audio with rich metadata (artwork, lyrics, comments) in one file — something wav historically lacked. AIFF is best for uncompressed audio on macos with embedded metadata — apple's equivalent of wav.
Why Convert WAV to AIFF?
Massive file sizes (10 MB per minute at CD quality) make it impractical for streaming or casual sharing — converting to AIFF overcomes this by providing stores uncompressed pcm audio with rich metadata (artwork, lyrics, comments) in one file — something wav historically lacked
AIFF is the right choice when you need to: exchanging uncompressed audio between macos-based music production tools
Gain broader compatibility — AIFF works with macOS (native), Logic Pro, GarageBand, Pro Tools, VLC, most DAWs; Windows support via third-party players
Your WAV files were created for storing master recordings and stem files for music production archives, but now you need a format suited to different workflows
WAV vs AIFF — Format Comparison
Waveform Audio File Format (.wav)

expand_more
WAV (Waveform Audio File Format) is best for professional audio production, recording studios, and sound design where zero quality loss is mandatory. AIFF (Audio Interchange File Format) is best for uncompressed audio on macos with embedded metadata — apple's equivalent of wav. Key tradeoff: WAV's advantage is completely uncompressed pcm audio — the raw digital representation of sound with no processing or quality loss whatsoever, while AIFF's advantage is stores uncompressed pcm audio with rich metadata (artwork, lyrics, comments) in one file — something wav historically lacked.
Pro Tips for WAV to AIFF Conversion
AIFF preserves full quality, so your output file will be as good as the WAV source — no need to worry about compression artifacts
Keep a backup of your original WAV file — while our conversion is reliable, having the source is always recommended
AIFF works especially well for: archiving studio masters on macos where wav metadata support was historically poor
Did you know? AIFF was based on Electronic Arts' IFF (Interchange File Format) from the Amiga — Apple adapted the Amiga's file structure for Macintosh audio, which is why AIFF uses big-endian byte order while WAV uses little-endian.
