About Video Trimmer — Free Online Tool

Video Trimmer keeps the stretch of a video between a start and an end time and throws the rest away.

The engine seeks to your start time before it opens the file, which keeps that seek fast even on a long recording, and then writes exactly the span you asked for. The cut is always re-encoded to H.264 rather than stream-copied, and that is a deliberate trade: a copy has to begin at a keyframe, which can sit seconds away from the point you chose, while re-encoding puts the first frame where you actually put the marker. The cost is time — a trim takes roughly as long as the piece you kept, not the instant a copy-mode cut would. An end time past the end of the file is refused with the real duration quoted.

Trimming happens in your browser, so the full recording never leaves your drive — including the part you are cutting off, which is often the reason for trimming in the first place.

Cutting the dead air off the start of a screen recording, pulling a highlight out of a long match or stream, removing a fumbled take from the end of a video message, and shortening a clip to fit a platform duration limit.
