Singers and cover artists
Drop a backing track into a key you can actually sing, instead of straining at the top of a chorus written for someone else.
Change the key
Drop in a track. It reads the original key first, so you can pick where you want it instead of guessing at semitones.

Song Key Changer
Transpose any song to a different key. A free online pitch changer that shifts semitones, jumps straight to a target key, or moves the track into your own vocal range — all in your browser.
How it works
How to change the key of a song
1Step 1
Drop in the track
Any backing track, karaoke version, sample or full mix. The pitch changer reads it locally — the file never leaves your device, so there is no upload wait.
2Step 2
Pick where you want it
Step by semitones, choose the target key outright, or pick a voice type and let it transpose the song into that range. The tempo stays exactly where it was.
3Step 3
Listen, then download
Preview updates as you move the controls — no re-render between takes. When it sits right, export it as an MP3 or a WAV, with no watermark.
What you can do
A Pitch Changer That Speaks in Keys, Not Just Semitones
Three ways to say the same thing, so you can use whichever one you actually think in.
Change the key of a song without touching the tempo
The pitch shift is independent of playback speed, so a track moved from G major to A major still runs at its original BPM. Nothing drifts out of time with the rest of your session.
A pitch shifter with semitone precision
Twelve semitones either way, one key at a time, with the resulting key shown as you move. Small moves stay clean; the tool tells you when you are getting into territory where a stretched track starts to sound processed.
Transpose a song to fit your voice
Pick bass, baritone, tenor, alto, mezzo-soprano or soprano and the track moves to the key that usually sits best in that range. Every other tool asks how many semitones you need — which is exactly the question a singer cannot answer.
Preview live, export clean
Move the controls while the track plays and hear the change immediately, then download it as an MP3 or a full-quality WAV. No watermark, no account, no queue — because the rendering happens on your own machine.
Who it's for
Made for Anyone Whose Song Is in the Wrong Key
The key a record was cut in has nothing to do with the key you need it in.
02
Mashup and remix makers
Move one track to meet the other, then check the Camelot codes to confirm they sit together.
03
Instrumentalists
Put a play-along in a key that works for a B♭ horn, a capo position or an open tuning.
04
Choirs and worship teams
Take a recording down a few semitones so a congregation or a section can reach the whole melody.
FAQ
Key and pitch questions
Drop the file into the tool above. It detects the original key, then you either step by semitones, choose the key you want from the list, or pick a vocal range and let it work out the move. Preview it, then download the transposed track as an MP3 or a WAV.
Twelve either way, which is a full octave up or down. In practice anything past about three semitones starts to sound stretched on a full mix — the tool flags that point so you can listen before committing.
No. Pitch and tempo are shifted independently here, so transposing leaves the BPM exactly where it was. There is a separate speed control if you want to move both — and a pitch lock switch that decides whether speed changes drag the pitch with them.
Pick your voice type from the vocal range presets and start there — the tool moves the track towards the key that usually sits best for that range. Then nudge a semitone at a time while you sing along. Treat the preset as a first guess, not a diagnosis: ranges vary enormously between singers.
Because pitch shifting a finished mix means re-synthesising every instrument at once, and the further it moves, the more artefacts add up. Vocals and cymbals show it first. A semitone or two is usually inaudible; five or six will be obvious on anything but a sparse arrangement.
No. Both the key detection and the pitch shifting run inside this page as WebAssembly and Web Audio, so the track stays on your device. That is also why there is no queue and no account. The one limit is 50 MB per file, because your browser has to decode it in memory.
The full track at your current settings, as a 320 kbps MP3 or a 16-bit WAV — your pick. No watermark, no length trimming. Free, and without an account.
No — this works on audio. It shifts the pitch of a recording; it does not rewrite notation or a chord chart. If you have the audio and need the chart, transpose the audio here and read the new key off the result.
