Uses ffmpeg.wasm: about 30 MB is downloaded the first time, then cached. Processing speed depends on your device — a 1-minute 1080p clip takes roughly 1–3 minutes.
● Your video is processed locally in your browser and never uploaded. Large files need a recent computer with enough memory.
How it works
Play the video and use the buttons to mark the start and end, or type the times. Fast mode copies the original streams without re-encoding — instant and lossless — but can only cut at keyframes, so the start may move by up to a few seconds. Precise mode re-encodes the clip to cut at the exact frame.
