About Trim Audio

Cut an audio file down to the part you want. Mark a start and end on the waveform and this MP3 cutter slices the clip with ffmpeg.wasm in the original format — great for making ringtones, trimming silence, or grabbing a quote from a recording.

Trimming runs entirely in your browser with no upload and no signup, and it works offline. Your audio never leaves your device.
