Video Trimmer is a free, in-browser tool for cutting a video to a start and end point. Fast mode copies the stream without re-encoding, so it is lossless but cuts snap to the nearest keyframe. Exact mode re-encodes to H.264 for frame-accurate cuts and is always used for WebM. The result downloads as an MP4.
