# Trim audio — cut & fade in your browser, no upload

> Cut and fade audio, trim MP3 or WAV to the part you need, in your browser. No upload — the edit runs on your device and the file stays there.

Cut an audio file down to the section you want and add fade-ins or fade-outs. The edit runs on your device, so the recording is never uploaded.

Trimming audio is the everyday task behind ringtones, podcast pickups, and pulling a clean sample out of a long recording. Doing it locally keeps interviews, voice notes, and unreleased tracks off any server.

Set the in and out points, then add short fades so the clip starts and ends without an abrupt click. The cut is precise, and you control the export format to trade file size against fidelity.

To even out loudness across a clip, use Normalize; to strip vocals for a backing track, use the Vocal remover; and to switch formats, use the Format converter.

## How to

1. **Add the audio.** Drop an MP3, WAV, or other audio file onto the tool or browse for it.
2. **Set the range.** Choose the start and end of the segment you want to keep.
3. **Add fades.** Optionally fade the start and end in and out for a clean edit.
4. **Download.** Export the trimmed clip locally and save it.

## FAQ

### Can I use this as an MP3 cutter?

Yes. Load an MP3, set the range, and export just that part — a ringtone, a sample, or the good take from a long recording.

### Do fades change the whole track?

No. Fades apply only to the start and end of your selected segment, easing it in and out without touching the middle.

### Will trimming reduce audio quality?

Trimming itself does not degrade the audio; exporting to a lossy format re-encodes it, so choose WAV or a high bitrate to preserve fidelity.

### Is my audio uploaded to trim it?

No. The clip is processed in your browser tab; the file's bytes never leave your device.
