Are my WebM 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 WebM to MOV 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 WebM to MOV lose quality?

MOV 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. Video is re-encoded rather than copied, so some detail is lost even at the highest setting. Subtitle tracks and chapters are not carried over.

Do I need to install anything to open MOV files?

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