Audio Trimmer
Audio Trimmer is a free online editor for cutting audio precisely. Upload a file, drag the start and end points directly on its waveform, preview the selection, and export it as MP3, WAV, M4A, FLAC, OGG, or Opus.
Waveform analysis, trimming, and conversion all run locally in your browser, so files are never uploaded. It works well for ringtones, interview highlights, podcast excerpts, and music samples.
How to Use
- Choose or drop one audio file up to 100 MB
- Drag the waveform handles, or move the entire selection to set the section to keep
- Preview the selection and choose an export format and quality
- Export, preview the result, and download it
FAQ
Is my audio uploaded to a server?
No. Waveform analysis, trimming, encoding, and downloading all happen in your current browser.
Which export formats are available?
You can export MP3, WAV, M4A, FLAC, OGG, and Opus. Lossy formats also include three practical quality presets.
How can I set an exact trim time?
Drag either waveform handle, enter seconds in the start and end fields, or use the arrow keys to nudge the focused handle.
Why does the editor prepare an engine the first time?
The tool loads an FFmpeg WebAssembly core of about 31 MB. Once cached by the browser, later visits usually do not download it again.
