How to cut or trim audio without losing quality

Select a file, enter the start and end in seconds or hh:mm:ss, then press Cut. The tool keeps the original format and copies the selected segment without re-encoding whenever the container supports it.

Supported formats

MP3, WAV, M4A, OGG, MP4, WebM and MKV. For long recordings, enter the timestamps directly.

Private by design

FFmpeg runs inside your browser. Voices, interviews and private recordings never leave your device.

If you first need to separate sound from a video, use Extract audio. You can also convert the result with MP3 to WAV or WAV to MP3.

Web vs Desktop

Use web for fast tasks. Download the App for heavy duty.

The browser is great for quick, daily tasks like generating a UUID, verifying a hash, or converting a color. But if you need video/audio conversion, archive compression, larger files, or long batches, the Nua Convert desktop application gives those jobs a native local workspace without browser memory limits.
