Change the pitch or key of a song

Change Pitch shifts audio up or down by semitones without changing its length. Musicians use it to move a song into a key that suits their voice or instrument; it's also fun for making voices deeper or higher.

Shift by up to 12 semitones, a full octave, either way, in half-semitone steps.

Choose an audio file, then move the pitch up or down, up to 12 semitones either way, then pick the format and download. It's free, there's no sign-up, and it runs in your browser, so the file never leaves your device.

Good to know

  • One semitone is one piano key; 12 is an octave. Musicians use this to change a song's key.
  • Large shifts sound less natural, especially on voices.
  • The first time you use an audio or video tool, your browser downloads our 31 MB processing engine. It's kept for next time, so later runs start straight away.
  • This tool runs in your browser. Very large files depend on your device's memory.

Change pitch: common questions

How do I change the key of a song online?
Choose the song, move the pitch up or down by the number of semitones you need, and save. Two semitones is a whole step, for example from C to D.
Will it sound natural?
Small shifts of one to three semitones usually do. Large shifts, especially on voices, sound more processed.
Does changing pitch change the speed?
No. The length stays the same. To change speed, use Change speed.
Is Change pitch free?
Yes. Change pitch is free, works without an account and adds no watermark, for files up to 500 MB. Pro raises that to 2 GB.
Are my files uploaded to a server?
No. Change pitch runs in your web browser, so the file is read on your own device and never sent to ConvertFile.
Does Change pitch work on Mac, Windows, Android and iPhone?
Yes. It runs in any modern web browser, with nothing to install. Very large files work best on a desktop or laptop, because in-browser tools use your device's memory.
