Frequently asked questions

Can I use this as an MP3 cutter?
Yes. Drop in an MP3, set the start and end points on the waveform, and export the section you want as a new MP3. It is a fast way to cut a ringtone, a sample or a single line out of a longer recording.
How precise can I be?
You can set the start and end down to a hundredth of a second using the sliders, and drag the waveform handles for a quick visual cut. Preview the selection before you export so the result is exactly what you expect.
Will trimming reduce the quality?
Exporting to WAV keeps the audio lossless. Exporting to MP3 re-encodes the clip at a high bitrate, so any quality change is minimal and usually inaudible. For master-quality edits, choose WAV.
Is it really free, and is there a watermark?
It is free and there is no watermark, no sign-up and no email wall. You get the full-quality file straight back, with nothing added and nothing held behind a paywall.
Is my file uploaded to a server?
No. Everything runs locally in your browser. Your file is read and processed on your own device, nothing is uploaded, and nothing is logged or stored.
