When to convert WAV to AIFF
Use this conversion when your destination needs AIFF and you have a WAV source. Keep the original so you can compare the result or try another supported format.
Audio is decoded and re-encoded using format-specific defaults. Sample format and some metadata may change. Embedded cover art is omitted. A lossless destination cannot recover detail lost in the source.

Tips for Converting WAV to AIFF
Practical advice to get the best results from this conversion.
Why this conversion is worth doing
WAV Audio has a known limitation: very large file sizes (approximately 10 MB per minute for CD quality). AIFF Audio addresses this with a key advantage: completely lossless with full PCM audio quality. Converting from WAV to AIFF is most worthwhile when this specific trade-off matters for the way you intend to use the file.
Match the format to the actual workflow
WAV Audio is most commonly used for professional audio recording and production, while AIFF Audio is the standard for professional audio production on macos. If your workflow is closer to the second pattern, converting makes sense. If you are still working in a context where WAV is the norm, converting may create unnecessary compatibility friction with collaborators or tools that expect the source format.
Watch for this limitation in the AIFF output
AIFF Audio has its own limitation worth understanding before you commit: very large file sizes comparable to WAV. After the conversion completes, open the AIFF file and verify that this limitation does not affect your specific use case — for some workflows it is irrelevant; for others it can be a deal-breaker.
Understand lossy vs. lossless before converting
Converting from a lossy format like MP3 to a lossless format like FLAC or WAV does not restore lost audio data — it only changes the container. If you need true lossless quality, always start from an uncompressed or lossless source. Converting lossless to lossy, however, is a valid way to reduce file size for streaming or mobile playback.

Source Format
WAV Audio
audio/wavWAV (Waveform Audio File Format) is an uncompressed audio format developed by Microsoft and IBM, storing raw PCM audio data in a RIFF container. It preserves the full quality of the original audio recording with no compression artifacts. WAV files are commonly used in professional audio production where lossless quality is essential.
Advantages
- Completely lossless with no compression artifacts whatsoever
- Universal support in all audio editing software and operating systems
- Simple format that is fast to read, write, and process
Limitations
- Very large file sizes (approximately 10 MB per minute for CD quality)
- Metadata support and preservation vary across audio software
- Impractical for streaming or portable device storage due to size
Common Uses
- Professional audio recording and production
- Master audio archival and studio workflows
- Audio editing and processing intermediate format
Target Format
AIFF Audio
audio/aiffAIFF (Audio Interchange File Format) is an uncompressed audio format developed by Apple, based on the IFF (Interchange File Format) structure. Like WAV, it stores raw PCM audio data at full quality, but uses big-endian byte ordering. AIFF is the standard uncompressed audio format in macOS and professional audio production on Apple platforms.
Advantages
- Completely lossless with full PCM audio quality
- Native support in macOS and all Apple audio software
- Supports embedded metadata including loop points for music production
Limitations
- Very large file sizes comparable to WAV
- Less universal than WAV on non-Apple platforms
- Not suitable for portable use or streaming due to file size
Common Uses
- Professional audio production on macOS
- Apple ecosystem audio recording and editing
- Music production sample libraries and loop files
