Audio Trimmer

Pick an audio file, listen to it, mark the start and end of the section you want, and download that segment on its own. Trimming a voice memo or a music sample this way keeps the recording on your machine rather than handing it to a service.

Web Audio decoding varies by browser. Export is uncompressed 16-bit WAV only; this tool does not claim MP3 or AAC encoding.

How to use

  1. Choose the audio file you want to trim.
  2. Set the start and end points of the section to keep.
  3. Download the trimmed clip.

Frequently asked questions

What formats can I load?
Anything your browser’s Web Audio API can decode, which normally covers MP3, WAV, M4A/AAC and OGG. Support is browser-dependent, not something this tool controls. The output is always WAV.
Is my recording uploaded anywhere?
No. The file is decoded in the page and the trimmed segment is written straight back to your downloads folder.

Privacy

Audio is decoded and trimmed entirely in your browser using the Web Audio API. The file is never uploaded anywhere.
