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 AAC to MP3?

AAC is the modern lossy format, better than MP3 at the same size. MP3 is the format that plays on absolutely everything. Converting is how you move a file from the first situation to the second.

What will the MP3 file be?

MP3 at VBR quality 2 (around 190 kbps), transparent for most listening and playable on everything.

Does converting AAC to MP3 lose quality?

A little, because both are lossy: the AAC file was already compressed, and MP3 compresses again. At this setting it is rarely audible, but keep the original if you may need to convert it again.

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.
