Change the Key of a Song Online

Change a song's key — transpose it up or down by semitones — without speeding it up or slowing it down. Perfect for matching a singer's range, transposing for an instrument, or practising in a different key. Free, in your browser, nothing uploaded.

How to change song key

1. Open the pitch shifter. Go to the free pitch shifter — no account, no install.
2. Add the song. Drop in the audio file. It stays in your browser.
3. Shift the key. Move up or down in semitones (half-steps) — e.g. +2 to raise the key a whole tone, −3 to lower it.
4. Preview. Play it back to find the right key; the tempo stays exactly the same.
5. Download. Save the transposed audio.

Why change a song's key

Singers transpose a song down to fit their range (or up for a brighter sound); instrumentalists transpose to an easier key or to match another instrument; and learners practise in different keys. Because the pitch shifter changes pitch in semitones, you can move a track to any key precisely.

Key change vs. speed — they stay separate

Changing the key is not the same as speeding up or slowing down. This tool shifts the pitch while keeping the tempo unchanged, so the song plays at the same speed in a new key. (If you want to change speed instead, use the speed changer.)

Frequently asked questions

How do I change the key of a song online for free?

Open SnipSound's free pitch shifter, drop in the song, and shift it up or down in semitones until it's in the key you want. Preview it and download — free, in your browser, nothing uploaded.

Can I change the key without changing the speed?

Yes — the pitch shifter changes pitch independently of tempo, so the song stays at the same speed in the new key.

How much can I transpose a song?

Up or down by semitones (half-steps) across a wide range — for example +2 to raise a whole tone, or −5 to drop it a fourth. Larger shifts change the character of the sound more.

Is my audio uploaded anywhere?

No — it runs entirely in your browser, so your song never leaves your device. No account, no upload.
