Shift pitch up or down without changing tempo.
Yes. Changing audio pitch on FormatGrid is completely free, with no watermarks, file limits, or account sign-up required.
Nowhere. Your audio files never leave your device — FormatGrid never uploads, transmits, or stores them on any server. All audio processing happens locally in your browser's memory and is discarded once you close or refresh the tab.
No. FormatGrid uses the Web Audio API's native detune parameter, which shifts pitch without changing playback speed or duration. Your audio stays the same length, only the pitch changes.
Most online pitch shifters upload your files to a remote server, process them there, then download the result back. FormatGrid performs every step locally on your device, eliminating upload time, processing queues, and download delays.
