How to change a song's key (for singing)
If a song sits too high or too low for your voice, you can transpose it to a more comfortable key — raising or lowering the pitch in semitones without changing the speed — right in your browser, for free, with nothing uploaded.
Change the key in 3 steps
- Open the Pitch & Tempo Changer and drop your song in. Choose or drag an MP3, M4A, WAV, OGG or FLAC — it loads locally and is never uploaded.
- Move the Pitch slider. Each step is one semitone — slide down (e.g. −2) to lower the key, or up to raise it. Leave Speed at 100% so only the key changes, not the tempo.
- Preview & download. Press Preview result to hear the new key, then save as MP3 or WAV.
Frequently asked questions
Is it free?
Yes — completely free, with no sign-up, no watermarks, and no limit on how many songs you transpose.
Does changing the key also change the speed?
No. Pitch and tempo are handled independently, so you can change the key while the speed stays exactly the same.
Can it change the key of just the vocals?
No. It shifts the pitch of the whole track together — it's a key changer, not a vocal isolator, so it can't transpose the singer separately from the instruments.
Will it still sound natural?
Small shifts of a few semitones sound the most natural. Larger shifts (around six semitones or more) start to sound artificial, which is normal for any pitch-shifting tool.
Are my files uploaded anywhere?
No. Decoding and processing happen locally in your browser, so your song never leaves your device.
