How to Trim Audio Online? Cut a Clip by Start/End Time
Explains how to cut an audio clip by start and end time, plus the privacy benefits and caveats of fully in-browser processing.
Audio trimming keeps only the sound between a start and end time, dropping the rest — handy for removing intros/outros or extracting highlights.
This tool uses FFmpeg (WebAssembly) in your browser, so the audio is never uploaded to a server — ideal for private material.
Stream copy is preferred to keep original quality; unsupported formats fall back to re-encoding.
Conversion runs entirely locally. Download the result before closing the tab — refreshing clears temp files.
