Why this pitch changer

New key, same tempo — in one drag.

Change a song to fit your vocal range, drop a sample into your project, or move a track into a key you can actually sing. It runs in your browser — MP3, WAV, FLAC, M4A, AAC and OGG, no sign-up, no watermark.

A full octave up or down, with 0.5-step fine tuning: ±12semitones
Speed never moves — only the pitch does: 1×tempo

Three steps

How to change the pitch of a song

01
Add your track
Drag an audio file into the drop zone, or click it to browse your device.
02
Pick your shift
Drag the semitone slider, tap the −/+ buttons to move one semitone at a time, or hit a quick preset. The preview updates as you go.
03
Audition and download
Flip between Original and Shifted to compare, then download the full track as WAV or MP3. Everything happens on this page.

No account, no watermark, no separate tool page to load. Your file never leaves your device.

What it does

What you can do with this audio pitch changer

Shift in semitones
Up to ±12 semitones, so you can tune a track to a specific key instead of guessing — with 0.5-step fine tuning on the slider.
Pitch without changing speed
The tempo stays put, which is the whole point of a dedicated pitch changer versus a speed changer.
Change the key of a song
The tool detects the original key and shows the new one as you move — for singers, G major to A major is the difference between a comfortable take and a wrecked one.
A/B against the original
Toggle between the original and the shifted preview at the same playback position before you commit.
No upload queue
Your file is not stored, logged or used for training — decoding, shifting and export all run locally.

Don’t mix them up

Pitch change vs speed change vs key change

These three get mixed up constantly, and mixing them up ruins finished audio. A speed changer alters pitch and tempo at once — that’s why speeding a track up also makes it sound like a chipmunk. A pitch changer decouples them, changing pitch while the speed stays put.

Key is where pitch is expressed musically: shifting a song by two semitones and saying you “changed the key” are the same thing described two different ways. If you only need the key name rather than new audio, that’s a key finder, not a changer.

Pitch

How high or low a sound sits.

Pitch changer: pitch moves, speed stays put.

Speed (tempo)

How fast the music moves.

Speed changer: both move together — the classic chipmunk tape effect.

Key

Where the pitch sits musically — G major, A minor.

Shifting two semitones and “changing the key” are the same operation.

Who it’s for

Who uses a song pitch changer

Singers & karaoke

Drop the track to a key that matches your range, then sing with the original backing.

DJs

Nudge a track into a compatible key before mixing, so the transition stops fighting itself.

Producers & beatmakers

Fit an acapella or sample into the key of a project you’re already working in.

Video editors & learners

Lift or drop a voiceover to sit with existing footage, or shift a phrase to hear it more clearly.

Formats

Accuracy, formats and limits

We accept MP3, WAV, FLAC, M4A, AAC and OGG up to 100 MB, and export the full track as WAV or MP3. Voice and solo instrument tracks shift cleanly; dense mixes and tracks with heavy reverb can smear slightly at large shifts, so keep an ear on the preview and stay within a few semitones if you’re chasing a natural result. The waveform shows the original and the shifted overlay so you can scrub to any section before exporting.

You get the file

Free pitch changer, no sign-up.

Single-track shifts are free with no daily cap and no account. Free doesn’t mean “free preview, paid download” here — you get the full file, as WAV or MP3, with no watermark. Your audio is never uploaded: it’s shifted and encoded right in your browser.

FAQ

Frequently asked questions

Semitones, speed, keys and privacy — the short answers.

Is this pitch changer free?

Yes. Shifting and downloading are free and unlimited, with no sign-up and no watermark.

Does changing pitch change the speed?

No. This tool changes pitch and keeps the tempo identical. If you want to slow down or speed up a track instead, use the BPM Changer.

How do I change the pitch of an MP3 or a song from my library?

Drop the file in, drag the semitone slider, then download. There’s no conversion step and no upload queue — the processed file is rendered and saved straight from this page.

Can I change the pitch of a song from a link, like YouTube or Spotify?

Not yet. The pitch changer works on audio files on your device, because streams can’t be decoded in the browser. Use a local copy of a track you have the right to use.

How many semitones can I shift?

±12 semitones — a full octave either way — which covers any key change a singer or DJ realistically needs. The slider also moves in 0.5-semitone steps for fine tuning.

How do I know what key the song will end up in?

The tool detects the original key and BPM after you add a file, then shows the new key and its Camelot code as you move the slider.

Does it work on vocals and voice recordings?

Yes — vocal tracks shift cleanly, which is why singers use it. If you want a cartoon-style voice effect, that’s a different tool (a voice changer), not this one.

Will the pitch change sound artificial?

Small shifts of one to three semitones are essentially transparent. Large shifts on dense mixes are audible — use the Original / Shifted toggle to check before you download.

Does my audio get uploaded to a server?

No. Decoding, pitch shifting and export all happen locally in your browser, so the file never leaves your device — safe for unreleased beats and private demos.
