Are my AAC files uploaded anywhere?

No. This conversion runs entirely inside your browser, so the file never leaves your device. You can confirm it yourself: open the network tab of your browser's developer tools and convert something. You will see the page load, plus the analytics and advertising the site is paid for with — and nothing carrying your file.

Is converting AAC to WAV free?

Yes. There is no account, no watermark and no limit on how many files you convert — it runs on your own machine, so it costs us nothing to let you. Files up to 100 MB are handled in the browser.

Does converting AAC to WAV lose quality?

No. WAV stores the same content without discarding anything, so the result is identical in quality to the original. The file gets much larger without getting better. What the original compression removed is gone; a lossless format can only preserve what is left.

Do I need to install anything to open WAV files?

No installation is needed for the conversion itself — it runs in the browser you already have. Opening the WAV afterwards needs whatever software normally handles Waveform Audio on your device.
