Nightcore is a style that takes an existing song and speeds it up while raising the pitch, producing a faster, higher, more energetic version — hugely popular on YouTube and TikTok. DefyAudio makes it in one place: raise the Speed slider for tempo and the Pitch slider for the signature high vocals.
Because Speed and Pitch are independent controls, you can dial in exactly the amount you want rather than being locked to a fixed preset. Everything runs locally in your browser, so it's instant and private.
Upload the song to DefyAudio, open the Effects tab, raise the Speed slider (about 1.2x–1.35x) and raise the Pitch slider a few semitones, then export.

No — everything runs in your browser, so your music stays private.
