About This Tool

Select exact start and end points, preview the chosen section, and export only the audio you need.

The editor decodes the source on your device, draws its waveform, and creates a new MP3 or WAV from the selected range. Optional fades can soften the beginning or end of a cut.

Practical tips

Preview the selection before exporting.
Use WAV when another editor will process the result.
Use a short fade to reduce abrupt cut boundaries.

Common questions

Does the cutter upload my audio?

No. The current cutter reads, previews, trims, and encodes the file in your browser.

Can it cut files that are not MP3?

Yes when your browser can decode the input. The finished file can be MP3 or WAV.

Why might a file fail to open?

Browser audio decoders differ. Try MP3 or WAV, a smaller file, or another current browser.
