How it works
ConvertCabin loads a local copy of FFmpeg in this browser tab and converts on your device — nothing is uploaded. The first file downloads the engine (~25 MB), then it's cached.
It stays free, unlimited and private, and works offline once loaded.

Enter a start and end time in seconds to keep just that part of the audio.
Tips & common uses
Trimming audio keeps a selected segment of a track and drops the rest. It's the quickest way to grab the part of a recording you actually need.
- Making a ringtone or alert from a few seconds of a song.
- Cutting silence from the start and end of a voice memo.
- Isolating a quote from a longer interview or podcast.
- Shortening a clip to fit a message or upload limit.
Frequently asked questions
How do I use Trim Audio?
Drop audio, enter start and end seconds, and download the trimmed clip.
What format do I get back?
The same format you put in — the section is copied without re-encoding.
Is my file uploaded?
No. It is converted on your device by a local copy of FFmpeg and never uploaded.
Does trimming reduce audio quality?
The kept section retains its original quality — trimming selects a portion rather than re-compressing the whole file.
Is the audio uploaded anywhere?
No. The trim runs entirely in your browser, so the file stays on your device.
