How to Cut and Trim Audio Files in Your Browser

Whether you're removing dead air from the beginning of a podcast, extracting a 15-second hook from a song, or cutting out a mistake from a voiceover, trimming audio is a crucial skill.

With our Free Audio Trimmer, you can easily cut your audio files visually, directly in your web browser.

Step 1: Load Your Audio File

Drag and drop your MP3, WAV, or M4A file into the main editor window. The engine will instantly decode the file and draw a massive, highly-detailed waveform so you can actually see the sound.

Step 2: Use the Trimming Handles

Once your file is loaded, you will see a highlighted segment representing your audio track on the timeline.

Trimming Audio Handles

To trim the beginning or end of the track:

1. Hover your mouse over the left or right edge of the audio block.
2. Your cursor will turn into a horizontal arrow.
3. Click and drag the edge inward to trim away the silence.

Step 3: Splitting the Audio (The Scissors Tool)

If you need to remove a mistake in the middle of the track, you need to use the Split tool:

1. Select the Scissors tool from the toolbar (or press 'C' on your keyboard).
2. Click anywhere on the waveform to instantly slice the audio block into two separate pieces.
3. You can now select the piece you don't want and press the Delete key (or the trashcan icon) to remove it entirely!

Step 4: Export Your Trimmed File

Once you have cut the audio down to size, click the Export button in the top right. You can download the result instantly as a high-quality WAV or a compressed MP3 file.
