Which target should I pick?

-14 LUFS for YouTube, Spotify and similar platforms; -16 LUFS is the usual podcast target; -23 LUFS for broadcast and film.

How is this different from just turning the volume up?

Raising the volume multiplies every sample and the loud parts clip. Loudness normalization matches perceived loudness and leaves headroom for the peaks.

📊Normalize Audio Online - Match Loudness (LUFS / EBU R128)

A pile of files at wildly different volumes, so you keep reaching for the volume knob? This aligns them to the same perceived loudness (LUFS) rather than just multiplying the level, so nothing clips and a whole batch ends up consistent. Spoken-word recordings can use the dynamic mode instead, which evens out uneven speech.
