Audio trimmer

Cut a clip out of a local audio file between two times and export it as uncompressed WAV.

Decoded and trimmed in this browser. Nothing is sent anywhere.

Decodes with the browser's Web Audio decoders (mp3, m4a/aac, wav, ogg, webm all work where the browser supports them) and exports uncompressed 16-bit WAV — no lossy re-encode, and no other output format. Files up to 200 MB; clips up to 60 minutes.

How to use

  1. Choose an audio file.
  2. Set the start and end time.
  3. Trim and download the WAV.

What it supports

Decodes whatever the browser's audio engine can read (mp3, m4a/aac, wav, ogg, webm…) and exports 16-bit PCM WAV only — no mp3 re-encode or format conversion. Files up to 200 MB; clips up to 60 minutes.
