How to Trim Audio Files on Windows & Mac for Free

Trimming the dead silence off the beginning or end of an audio recording is the most common audio editing task.

While you could download heavy software like Audacity (on Windows) or Garageband (on Mac) just to make a 2-second trim, there is a much faster way. You can use our Free Audio Trimmer directly in your web browser.

Why Use an Online Audio Trimmer?

If you just need to shorten an audio file, downloading and learning how to use a professional Digital Audio Workstation (DAW) is overkill. Our online audio trimmer is designed to do one thing perfectly: let you crop an audio file in seconds. And because it runs locally in your browser, it's just as secure as using a desktop app.

How to Trim Your Audio:

Step 1: Drag and Drop

Open the Audio Trimmer and drag your MP3, WAV, M4A, OGG, or FLAC file into the window. It works perfectly on Chrome, Safari, Edge, and Firefox on both Windows and Mac.

Step 2: Drag the Trim Handles

Once the waveform appears, you will see white handles on the far left and right edges of your audio block. Simply click and drag these handles inward. The section of the audio that becomes greyed out is the part that will be removed. You can hit the Play button at any time to hear exactly how your new trimmed file will start and end.

Step 3: Export

When you have set your trim points perfectly, click the Export button. The file will instantly save to your Downloads folder, ready to be shared or uploaded.

It really is that simple! No software installation, no accounts, and no watermarks.
