Convert AIFF to WAV
Move Apple's AIFF into a plain WAV container without touching the audio. It all runs in your browser, so nothing is uploaded.
Why convert AIFF to WAV?
AIFF and WAV hold the same uncompressed PCM samples, just wrapped differently (AIFF is big-endian, WAV here is little-endian). You convert AIFF to WAV when a Windows tool or a picky plugin insists on WAV, or when you are handing a session to a collaborator on a PC where WAV is the house standard. It is also what many CD burning apps, sample libraries, and older hardware samplers expect. If your files came out of Logic or an old iTunes workflow as AIFF and the next stop is a Windows DAW, WAV is the clean interchange choice.
Quality and file size
Because both formats are lossless and uncompressed, this is a container swap, not a re-encode. The samples come out bit-for-bit identical, with no quality change in either direction. File size stays about the same, roughly 10 MB per minute at CD quality, since neither format compresses. The practical tradeoff is metadata: WAV carries fewer tags than AIFF, so some notes or markers may not survive the move, while playback and editing support on Windows gets broader.
AIFF to WAV: common questions
Does converting AIFF to WAV change the audio quality?
No. Both are lossless PCM, so the audio is preserved bit-for-bit. You are changing the container, not the sound.
Will the WAV file be bigger or smaller?
About the same size. Neither AIFF nor WAV uses compression, so a CD-quality file stays around 10 MB per minute either way.
Why bother if the audio is identical?
Compatibility. Many Windows editors, CD burners, and hardware samplers want WAV, and it is the common interchange format when your collaborators are on PC.
Is anything uploaded to a server?
No. The conversion runs locally in your browser through FFmpeg compiled to WebAssembly. Your AIFF never leaves your device, and we never see or store it.
