Not in this step. The converter has no loudness setting and leaves the level as it is. To even out the volume, run the finished M4A through a Normalize tool on this site.

Yes. Uploaded AMR files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted M4A are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.

The converter does not change the level: it has no gain or normalize setting. If you hear a difference, your player or media library probably applies ReplayGain or its own volume leveling on playback; turn that off to hear the M4A as it is.
