Transpose any clip up or down by semitones while keeping the original tempo and length. Great for matching keys, vocal effects, and quick transposition. Runs entirely in your browser — nothing is uploaded.
Try it
Shift the key of a track without speeding it up or slowing it down — no installs, no account.
MP3, WAV, OGG, M4A — up to 25 MB. We'll shift its pitch without changing the length.
How it works
The shifter decodes your file with your browser's audio engine, time-stretches each channel, then resamples back to the original length — so only the pitch changes, not the duration. Everything happens on your machine.
Step 1
MP3, WAV, OGG, M4A or FLAC — up to 25 MB.
Step 2
Choose -12 to +12; the length is preserved.
Step 3
Preview first, then save the pitch-shifted audio.
