Audio Trimmer

Trim and cut audio online — exact, free, nothing uploaded.

100% in your browser — nothing is uploaded

Audio Trimmer

This free online audio trimmer cuts an audio file down to the exact section you want to keep. Drag the handles to set a start and end point, hear the selection before you commit, and export just that region. It is the tool you reach for when a fifteen-second advert slot needs exactly fifteen seconds, when a podcast intro has to lose four seconds of silence at the top, when a sample needs to start on the downbeat, or when a ringtone has to be cut to the hook. Because it runs in your browser on the Web Audio API, files are never uploaded — which matters when you are trimming an unreleased demo or a client’s material. The trimmer works sample-accurately rather than by rounding to the nearest second, so a cut placed on a transient lands on that transient. Exports keep the original sample rate, and there is no watermark, no account and no queue. For anything longer than a single cut — joining two files, converting a format, changing the level — the other browser tools pick up where this one stops.

Can I trim a file without uploading it?

That is the whole design. Nothing leaves your device: the file is decoded, edited and exported entirely in the browser, which is why it works on unreleased material.

How do I cut a song to make a ringtone?

Trim to the hook, keep the length near thirty seconds, and export as WAV or M4A. Starting the cut on a beat rather than mid-phrase is what makes a ringtone sound deliberate.
