Audio Trimmer & MP3 Cutter

How to use the Audio Trimmer

Drag and drop an MP3, WAV or OGG file onto the upload zone, or click to browse. Once decoded, move the start and end range sliders to select the portion you want to keep. Hit Trim & Save WAV Clip and your trimmed audio will download instantly as a WAV file.

Why trim audio in the browser?

Cutting a ringtone, removing silence from a recording or clipping a sound bite usually means uploading the file to a converter. Here the audio never leaves your device, there is no size cap and no sign-up, and you can see the waveform to cut at exactly the right moment.

Step by step: trim a clip

1. Drop an MP3, WAV or OGG file onto the panel.
2. Look at the waveform and drag the handles to set the start and end of the clip.
3. Preview the selection to confirm the cut points.
4. Trim and download the shortened audio.

Quick reference

Format	Notes
WAV	Uncompressed, best quality, larger file
MP3	Small and universally supported, slight quality loss
OGG	Efficient, good for web playback

Cutting audio cleanly

• Zoom in on the waveform so you do not clip the first or last syllable.
• Export to WAV if you will edit the clip again, and MP3 for sharing.
• Trim a ringtone to just under the target length so it fades or loops cleanly.
• Always keep the original recording in case you need a different cut later.

Is it private and secure?

Yes. All audio decoding and trimming happens entirely inside your browser using the Web Audio API. No files are ever uploaded to any server, so your audio stays 100% private.
