LUFS describes perceived loudness, while true peak limits technical peaks. The presets account for these values and a suitable loudness range, so you do not need to calculate them yourself.
The output is a new file
The input is technically checked and returned as a new MP3 file. The original is never overwritten. The output is checked again for format, duration, and loudness after adjustment.
