No. This tool uses a simple RMS and peak scaling. For true LUFS loudness normalization use the server-side loudness normalizer.

Why not just max out the volume?

Peak-normalizing to 0 dBFS often causes intersample clipping on playback. -3 dBFS leaves headroom for safe playback across devices.

It will not clip the peak, but aggressive RMS targets can push transients above 0 dBFS. Watch the peak readout before export.
