Turn AIFF files into WAV
Turn your AIFF into a WAV. AIFF is uncompressed audio on a Mac, the Apple counterpart to WAV. The practical difference is that the result opens anywhere, which AIFF files do not. Your file never leaves your computer.

How to convert AIFF to WAV
- 1 Drop your AIFF .aiff or .aif or .aifc file onto the page, or click to browse for it.
- 2 Check the options. Nothing is thrown away on the way to WAV, so there is no quality dial to set.
- 3 Convert. The work happens on your own machine, so how long it takes depends on your computer and the file.
- 4 Download the WAV, or add more files and do the whole set in one go.
Why convert AIFF to WAV
- An AIFF will not open in a browser, so anything going onto a web page, into a document or into a message has to become a WAV first.
- Exactly as recorded, with nothing to unpack before it plays.
- Universally readable by audio software.
- Any step where further processing will happen.
- AIFF: less universally supported on Windows and web.
AIFF compared with WAV
How the two formats differ on the things that decide whether a conversion is worth making.
| Property | AIFF | WAV |
|---|---|---|
| File extension | .aiff | .wav |
| Browser support | Some browsers | Every browser |
| Introduced | 1988 | 1991 |
| Developed by | Apple | Microsoft and IBM |
Quality and what changes
Both sides are lossless, so every pixel survives the trip intact and converting back returns the same image. What changes is the size and what the file can carry: WAV stores the data without compression, so expect a much larger file.
- One WAV limitation to keep in mind: roughly ten times the size of a good MP3.
Questions about AIFF to WAV
Is my AIFF file uploaded anywhere?
No. The whole thing runs inside the browser tab you already have open. Your AIFF is read straight from your own disk, converted on your machine and handed back as a WAV. Nothing is sent anywhere, nothing is stored and there is no account.
Is there a file size limit?
There is no server-side limit because no server sees the file. The real ceiling is your device memory, since the input and the output both have to fit in the tab. A few hundred megabytes is usually fine on a desktop machine and considerably less on a phone.
Can I convert several AIFF files at once?
Yes. Add as many as you like and they are processed one after another, then offered as separate WAV downloads or as a single ZIP. Speed depends on your own processor rather than on a queue.
Does the converter work offline?
Yes, after the page has loaded once. The engine is cached by the browser, so you can disconnect, reload and keep converting. That falls out of doing the work locally rather than being a separate mode you switch on.
