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 WAV to M4A?

WAV is uncompressed and lossless, which is why the files are enormous. M4A is the Apple container for AAC, and what iTunes and Voice Memos produce. Converting is how you move a file from the first situation to the second.

What will the M4A file be?

AAC at 192 kbps in an M4A container - the format iTunes, Apple Music and iPhones use.

Does converting WAV to M4A lose quality?

A little, by design - M4A is lossy. At this setting the difference is inaudible to most listeners.

Does converting lose quality?

Going to a lossless format never does. Going to a lossy one always does, though usually not audibly at the settings used here.
