How to autotune your voice online
- Press Record your voice and sing or rap for up to a minute, or upload a WAV, MP3 or M4A file.
- Leave Song key on Auto and it listens to your first notes and finds the key (and major or minor) by itself. If you know the key of your beat, set Song key and Scale to match it.
- Pick a style. Hard Tune gives the stepped, robotic sound; Natural Pop fixes pitch without being obvious.
- Press Play result, compare with Play original, then Download WAV.
Is this autotune free?
Yes. The online tool is free with no signup, no watermark and no time limit. Everything runs in your browser, so your voice is never uploaded to a server. It uses the same pitch-correction engine as our Tune plugin, which you can run live in Ableton, FL Studio, Pro Tools and Logic.

Why does my autotune sound wrong?
Almost always the key is wrong. If the tool pulls notes the singer didn't mean, it's snapping to a scale that doesn't match the song. Try the relative major/minor (C Major and A Minor use the same notes), or switch Scale to Chromatic, which corrects to the nearest semitone and can't be in the wrong key. Very breathy or whispered takes also give the pitch detector less to work with.
