Key features

A thumbnail strip spanning the full video lets you see content at a glance. Drag the start and end handles to frame your cut precisely.

No re-encoding

Video and audio streams are copied directly from the source using FFmpeg stream-copy mode. This means zero quality loss and near-instant output regardless of file size.

In-browser preview

Play the selected clip inside the timeline before committing the trim - no guessing required.
