Cut a clip down to just the part you want. Set a start and end point and export that segment (WebM). Runs in your browser — your video never leaves your device.
How it works: the selected segment is re-recorded in your browser, so trimming runs in real time (about as long as the segment) and exports a WebM. Best for short clips you want to crop down quickly.
How to trim a video
Drop in your clip, drag the start and end sliders to the part you want to keep, choose whether to keep the audio, and export. The result is just that segment, ready to download. All processing happens locally in your browser — your video is never uploaded.
