Online video merger

Combine clips without starting a full editing project.

OneCut turns separate camera files into one finished video. Add MP4, MOV, M4V, or WebM clips from your phone, camera, or computer. When recording dates are available, OneCut uses them to build the first sequence—even when the files came from more than one camera.

You stay in control before export. Reorder any clip, trim rough starts and stops, add short timed captions, and make simple colour adjustments. The original files on your device are not changed. The result is one shareable MP4 at 1080p, 1440p, or 4K, with the sound kept in place.
