Why this runs on your computer

There is no upload: The work happens in this tab. Your file never travels, so there is no copy of it anywhere but your own disk.
Nothing to delete later: Sites that upload promise to delete your file afterwards. That promise only matters because the file was theirs to hold.
It works with the Wi-Fi off: The honest test. Turn off your connection and the tools keep working, because everything they need is already here.

Questions

Why convert WebM to WMV?

WebM is small and made for the web, though older players and editors ignore it. WMV is a Windows Media container that tends to be the odd one out on a Mac. Converting is how you move a file from the first situation to the second.

What will the WMV file contain?

Real Windows Media: WMV8 video and WMA sound in an ASF container, which Windows Media Player, PowerPoint and older Windows editors open without extra codecs.

Is the picture re-encoded?

Yes. WMV cannot carry the VP9 video a WebM file normally holds, so the picture is encoded again, at a quality setting high enough that the difference is hard to see.

Is the sound kept?

Yes. The audio track comes across with the picture - copied when WMV can hold it as it is, converted when it cannot.

How long does it take?

Repackaging takes seconds. A full re-encode runs in this tab on one processor core, so a long HD video takes a while - but there is no upload or download to wait for.
