Are my MOV 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 MOV to AAC 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 MOV to AAC lose quality?

AAC is a compressed format, so some data is discarded. At the default setting the difference is not visible; you can raise the quality setting if you need to be certain. Only the first soundtrack is kept. A film with a second language or a commentary track loses it.

Do I need to install anything to open AAC files?

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