Trim videos losslessly

Drop a clip, set start and end seconds. ffmpeg.wasm stream-copies the bytes between those points - no re-encode, no quality loss.

Runs locallyStream copyffmpeg.wasm

Stream-copy mode trims on keyframe boundaries. Cuts may snap to the nearest keyframe before your start time.
