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.

About Trim Video

Enter a start and end time in seconds to keep just that part of the video.

Tips & common uses

Trimming keeps a chosen start-to-end section of a clip and discards the rest, without re-encoding the whole file. It's the fastest way to cut a video down to the part that matters.

  • Removing dead air at the start and end of a recording before sharing.
  • Clipping a highlight from a longer screen recording or gameplay capture.
  • Cutting a video to fit a platform's length limit for stories or short-form posts.
  • Isolating one moment to send without uploading the full-length file.

Frequently asked questions

How do I use Trim Video?
Drop a video, enter start and end seconds, and download the trimmed MP4.
Is my file uploaded?
No. It is converted on your device by a local copy of FFmpeg and never uploaded.
Does trimming re-compress the video?
Trimming keeps the original quality of the section you keep — it isn't re-encoded from scratch, so there's no extra generation loss.
Is my video uploaded to trim it?
No. The trim happens in your browser on your own device; the file never leaves your machine.
