Convert AIFF to WAV

What a AIFF file is

AIFF is Apple's uncompressed PCM format — WAV's opposite number, same audio, different byte order and a container that handles tags rather better.

Where you run into it: Logic and Pro Tools sessions, Mac recordings, older Apple software that wrote it by default.

What it costs you: As big as WAV, and outside the Mac world rather less widely accepted.

What you get as WAV

WAV is raw, uncompressed PCM in a Microsoft container: the audio exactly as it was sampled, with nothing clever done to it.

Where you run into it: Recording sessions, sample libraries, video editors, anything that has to be edited rather than merely listened to.

What it costs you: It is enormous — roughly 10 MB a minute in CD-quality stereo — and it carries almost no tagging, so a folder of WAVs is a folder of filenames.

What this conversion actually does

Both sides are lossless, so this conversion is exact: decode the result and you get back the same samples you started with, bit for bit. Only the size and the container change. Nothing is at risk here, which makes it the one conversion you can run on an only copy without thinking twice.

How to convert AIFF to WAV

1. Drop your AIFF file onto the box above, or click it and pick the file.
2. Choose a quality if you want one — the default is the best the source can support.
3. Press Convert. The file goes to our server, ffmpeg does the work, and the result comes straight back.
4. Your WAV file downloads automatically. Both copies on the server are deleted as soon as the response is sent.

Frequently asked questions

Is converting AIFF to WAV free?

Yes, entirely, and there is no cap on how many files you convert. No account, no watermark, no trial.

Does converting AIFF to WAV lose quality?

No. Both formats are lossless, so the result decodes to exactly the same samples as the original — bit for bit. Only the file size changes.

How big will the WAV file be?

It depends which way you are going: FLAC typically stores the same audio in about half the space of WAV or AIFF, so the file either roughly halves or roughly doubles. The audio itself is identical either way.

Can I convert WAV back to AIFF?

Not here. AIFF can be read but not written by this converter — ffmpeg decodes it happily, and encoding back to it would mean a format almost nothing plays. If you need the original AIFF, keep it rather than recreating it.

Is my file uploaded anywhere?

The file is uploaded to do the conversion — nothing here runs in your browser — and both your upload and the converted result are deleted the moment the file is sent back. Nothing is stored and nothing is logged beyond the request itself.
