Audio trim

Trim an audio file and export WAV, MP3, M4A, AAC, OGG, FLAC or WebM.

Trim and convert audio

Open a recording, select the range on the waveform, listen to it and export it in the required format.

Trimming and conversion

Set the start and end on the waveform or type exact times, play the selection to check it, and export. The same tool converts between WAV, MP3, M4A, AAC, OGG, FLAC and WebM.

Private and free

Decoding and encoding run in the browser. The file is never uploaded, there is no account, and no credits are used, so a voice memo or an interview is never stored on a third-party server.

Typical uses

Cutting the silence off the start of a recording, keeping one answer from a long interview, making a ringtone-length clip, or turning a WAV into an MP3 small enough to send. Mono and stereo files are both supported.

Key features

  • Never uploaded

    The audio is trimmed inside the browser; nothing leaves the device.

  • Free, no account

    No sign-in and no credits. Load a file and cut it.

  • Exact cuts

    The start and the end can be set to the millisecond, and the selected part is exported.
