Cut Audio

Audio Cutter lets you trim a specific segment from any audio file by defining a start point and an end point in seconds. The resulting file contains only the selected portion, keeping the original format intact.

Using it is straightforward: select an audio file, set the start time and end time of the segment you want to keep (in seconds, with decimal support down to tenths), then click Cut. The browser automatically detects the file's total duration and pre-fills the end field to speed up the adjustment. Processing uses ffmpeg.wasm running locally — no data is transmitted outside your device at any point.

This tool is particularly useful for: extracting an interview clip to share on social media; removing silence or noise at the beginning and end of a recording; isolating a musical passage to use as a video soundtrack; creating short samples from longer tracks; saving only the relevant portion of a lengthy meeting or podcast recording.

The cut is performed using stream copy, meaning the audio is not re-encoded — original quality is fully preserved and processing is faster than a full transcode. The tool is free, requires no sign-up, and works in any modern browser including on mobile devices.
