Trim, cut, or crop your audio to the exact section you need — entirely in your browser.
Yes. Trimming audio files 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 trimming happens locally in your browser's memory and is discarded once you close or refresh the tab.
Most online audio trimmers 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.
Yes — cropping and trimming are the same thing here. Drag the start and end handles on the waveform, or type exact timestamps, to keep only the section you want, then export just that portion as a new audio file.
