About trimming audio
This tool trims an audio file to a chosen start and end time and downloads the clip — handy for ringtones, samples or removing silence. It copies the audio without re-encoding, so it is fast and lossless. It runs in your browser using ffmpeg in WebAssembly, so your file is never uploaded.
How Audio Trimmer works
How to use it
- Drop or choose an audio file.
- Set the start and end time (seconds or m:ss); you can set the start to the current preview position.
- Trim and download the clip.
How it works
The tool seeks to your start time and keeps the chosen duration, copying the audio stream directly rather than re-encoding. That makes it fast and keeps the original quality. Everything runs locally with ffmpeg compiled to WebAssembly.
Make a ringtone
Trim a song down to your favourite 20–30 seconds for a ringtone or alert, or cut a clean sample from a longer recording.
