How to convert AIFF to WAV
Add your AIFF files
Drag and drop AIFF files into the box or tap to choose them. The converter engine (about 31 MB) downloads once, the first time you convert.
Check the settings
WAV is lossless, so there's no bitrate to pick. Change sample rate or switch to mono under Advanced if a device needs it.
Convert and download
Click Convert, then download each WAV file or all of them as one ZIP.
Why convert AIFF to WAV?
Windows software and many hardware devices prefer WAV over AIFF.
What happens when you convert AIFF to WAV?
The samples are rewritten as 16-bit little-endian PCM WAV — identical sound, same size.
How does Fylo convert AIFF to WAV?
Fylo decodes the PCM audio in the AIFF with ffmpeg compiled to WebAssembly and encodes it with 16-bit little-endian PCM with no compression. Both formats are lossless, so the decoded samples are identical; only the container and file size change (a 3-minute song is ≈ 32 MB as AIFF and ≈ 32 MB as WAV). The original sample rate and channel layout are kept unless you change them under Advanced.
What's the difference between AIFF and WAV?
AIFF (Audio Interchange File Format) was created by Apple in 1988, based on Electronic Arts' IFF format. Like WAV it stores uncompressed PCM audio — just with big-endian byte order — so the two contain identical sound data at the same settings.
WAV was introduced by Microsoft and IBM in 1991 and, like AVI, uses the RIFF container. Most WAVs hold uncompressed PCM audio: CD quality (44.1 kHz, 16-bit, stereo) runs at 1,411 kbps, or about 10.6 MB per minute.

Frequently asked questions
Is anything lost?
No (24-bit sources are written as 16-bit).
Why do some apps reject AIFF?
AIFF is less common on Windows.
Is my AIFF file uploaded to a server?
No. Fylo runs ffmpeg, the same engine used by professional video tools, compiled to WebAssembly inside your browser. Your AIFF file is read directly from your device and never sent anywhere.
