PITCH CHANGER
100% LOCAL — NOTHING UPLOADSShift any audio up or down in semitones. Free, no account.
How it works
Your file is processed entirely in your browser with a time-stretch engine — it never leaves your machine. Shift vocals to fit a new key, or repitch a whole beat without touching tempo.
Does pitch shifting change tempo?
No — the time-stretch engine moves pitch independently. Tempo stays exactly where it was.
Is there a file size limit?
Keep files under 100 MB. Longer sessions? Split the file and process in parts.
What formats can I export?
24-bit WAV at the source sample rate. MP3 export is on the way.
Why does it say 100% local?
All processing happens on your device — nothing is uploaded, so your unreleased beats stay yours.
