Audio Trimmer
Trim any audio file — MP3, WAV, OGG, FLAC, M4A — to a precise start and end time entered as HH:MM:SS. A lossless stream copy keeps the output bit-identical to the source within that range, and everything runs in your browser so the file never leaves your device.
How to use this tool
- 01
Upload your audio
Drop in or choose any format FFmpeg supports — it's processed locally and never uploaded.
- 02
Set start and end times
Enter HH:MM:SS for both, or scrub the preview player to find the exact points.
- 03
Trim and download
Stream copy is near-instant and lossless when the codec allows; the file downloads in one click.
Why this matters
A raw recording almost never starts and ends where you want it to — there's a count-in, dead air, a fumbled intro, or a music bed that runs long. Cutting that down is one of the most common audio chores for podcasters, video editors, and musicians, and firing up a full DAW just to lop off thirty seconds is overkill.
This tool does it in the browser with a lossless stream copy, so the kept section is bit-identical to the source and nothing is uploaded — which matters for unreleased music and confidential interviews. Pair it with the Audio Merger to recombine separately-trimmed sections, or the Audio Fade In/Out tool to smooth the cut points, and you can assemble a clean episode without opening a DAW.
