Video Trimmer / Cutter

Cut a video down to a start and end time - processed entirely in your own browser using ffmpeg.wasm, so the file never leaves your device. The video engine (~30MB) downloads once the first time you use any Video Tool on this site, then stays cached.

Format: HH:MM:SS or MM:SS (e.g. 00:01:30 for 1 minute 30 seconds).

Uses a fast "stream copy" cut (no re-encoding), so it finishes almost instantly - the tradeoff is the actual cut point may land up to a second or two off your exact start time if it doesn't fall on the video's nearest keyframe.
