Why youtube creators use these
YouTube normalizes uploads to -14 LUFS, so anything you publish too quiet gets boosted (and anything too loud gets pulled down). Matching your levels before upload gives you control over the result. Beyond that, YouTube is forgiving on input format — but a clean WAV master uploaded once beats a re-encoded MP3 uploaded multiple times.

Open guide →-14 LUFS integrated. YouTube applies this normalization automatically; pre-mastering to that target means your video plays back at the loudness you intended, not what their algorithm decides.
WAV preserves the most quality through YouTube's re-encoding. If your video editor can't take WAV, an MP3 at 320 kbps is essentially the same in practice. Avoid going below 256 kbps — YouTube's encoder will compound the loss.
