AIFF to WAV Converter
AIFF and WAV are both uncompressed PCM. Same audio data, different headers. AIFF is big-endian (the Apple convention from the late 80s), WAV is little-endian (the Microsoft convention). The conversion just rewrites the header and flips byte order. There's no quality change, the sample values are preserved exactly.
How it works
Drop the AIFF
.aiff or the older 3-letter .aif extension. ffmpeg handles both.
Up to 200 MB
Pick bit depth (optional)
Default keeps the source bit depth. Choose 16-bit for distribution masters, 24-bit if the WAV will be processed further. Sample rate is preserved unless you override it.
Codec: pcm_s16le or pcm_s24le · standard RIFF

The WAV is bit-identical to the AIFF audio, just with a RIFF wrapper instead of an IFF wrapper.

Get Logic and GarageBand exports into everything else
AIFF is the uncompressed format Apple has used since the first Mac, so Logic Pro and GarageBand love to hand it to you. The trouble starts when you send that file to a collaborator on Windows, a distributor, or a sample library that expects WAV. This swaps the container without touching the audio, so the file drops into any DAW on the planet.
Nothing lost
A container swap, not a re-encode
AIFF and WAV hold the exact same PCM audio, the only real difference is byte order (Apple's big-endian vs Microsoft's little-endian) and the header. Converting just rewrites those, so the sample values come out identical. There's no compression, no resampling, no quality question. It's the safest conversion there is.
One heads-up
DAW markers don't always survive, export those directly
Standard tags like artist and title carry over fine, but DAW-specific extras, loop points, cue lists, region names, live in proprietary chunks and usually get dropped in any format conversion. If your workflow leans on those markers, export straight to WAV from your DAW instead. For plain audio, this is bit-perfect and runs entirely in your browser.
Frequently asked questions
Why is AIFF used by macOS and Logic Pro?
AIFF was the standard uncompressed audio format on the original Mac in 1988. Logic Pro inherited it. WAV came from the Windows side a few years later. Today both formats are essentially equivalent. Same PCM audio, different container conventions. Logic supports WAV import natively, and any DAW imports both, so the conversion is purely about preference or sending to systems that don't read AIFF.
Will markers and metadata transfer?
Standard tags (artist, title, album) transfer through ffmpeg's metadata copy. DAW-specific markers (loop points, cue lists, region annotations) usually don't survive the conversion. Those are stored in proprietary chunks each DAW reads from its own export. If you depend on markers, export from your DAW directly to WAV.
Is the conversion lossless?
Yes. Both formats store uncompressed PCM. ffmpeg copies the sample values into a new container. No resampling, no encoding, no quality change. The output WAV decodes to identical audio.
