How do I convert AIFF to WAV?

Add your AIFF file to the upload area above, then press Convert. The WAV file downloads straight to your device. You do not need an account, and there is no watermark.

Are my files uploaded to a server?

No. This conversion runs entirely inside your browser using WebAssembly, so the file never leaves your device — you can even disconnect from the internet after the page loads and it will still work.

Does converting to WAV reduce quality?

No. WAV is a lossless format, so the conversion preserves exactly what is in your AIFF file. Note that it cannot recover detail that was already discarded when the AIFF was first created — a lossless container does not undo earlier compression.

How large a file can I convert?

Up to 300 MB per file for this conversion. Because the work happens in your browser, the practical limit is your device's memory — larger files work on a desktop with plenty of RAM and may fail on an older phone.

Can I convert several files at once?

Yes. Add as many as you like and press Convert All. Each file is processed independently, so one failure does not stop the rest, and you can download everything together as a ZIP.

Can I use this on my phone?

Yes. FileTools360 works in mobile browsers on iOS and Android, including choosing files straight from your camera roll. Very large videos may run out of memory on a phone — those are better converted on a laptop.

AIFF and WAV explained

AIFF is Apple's uncompressed audio format, functionally equivalent to WAV but with better metadata support and big-endian byte order.

WAV stores uncompressed PCM audio — the raw samples, exactly as captured. A stereo CD-quality minute is roughly 10 MB, which is the price of having no compression whatsoever.

Where AIFF files come from: Mac audio production and older Apple software.
Where WAV is used: Recording sessions, sample libraries and audio editing.

AIFF vs WAV

The two formats solve different problems, which is why converting between them involves trade-offs rather than a straight upgrade.

AIFF compared with WAV
Property	Source	Target
Compression	Uncompressed	Uncompressed
Introduced	1988	1991
Browser support	Strong on Apple, decent elsewhere.	Universal.

AIFF is stronger at: Uncompressed and lossless. Better metadata handling than WAV. Standard in Mac audio workflows.
WAV is stronger at: Perfect fidelity with zero compression artefacts. No decoding overhead, so editors scrub instantly. Universally supported.

Why convert AIFF to WAV?

People make this switch when they run into the limits of AIFF: distribution, or interchange with Windows tools where WAV is safer. WAV is the better fit when recording, editing, mastering, or handing audio to another tool.

Be aware of the size trade-off: WAV is uncompressed, so expect the converted file to be considerably larger than the AIFF you started with.

AIFF limitations that prompt the switch: Very large files. Less universally supported than WAV.
What you give up: Very large files. No standard metadata support worth relying on.

Does converting AIFF to WAV reduce quality?

Both formats store the content without discarding data, so this conversion preserves it exactly. The file size may change because the two formats compress differently, but the content itself is unaffected.
