Trim video locally with frame-accurate or lossless keyframe-aware cutting, exact in/out marks, visual storyboard guidance, format and quality controls, and verified watermark-free exports.
Frame-accurate or losslessChoose precise re-encode or lightning-fast stream copy.
Visual in/out workflowPlayhead marks, timeline range and storyboard thumbnails.
Verified local exportDuration, codec, dimensions and SHA-256 checked before download.
Choose a video. Nothing is uploaded.
Local FFmpeg/WebAssembly with deterministic output verification. I/O mark the playhead when you are not typing in a field.
Editing advisorFrame-accurate mode is recommended when the exact first frame matters. Lossless mode avoids re-encoding but starts on a nearby keyframe.

Two kinds of trimming
Frame-accurate decoding/re-encoding gives reliable in/out timing. Lossless stream copy is dramatically faster and preserves source quality, but its first visible frame can be constrained by keyframes.
Built for exact marks
Use the player, numeric fields, sliders or keyboard I/O marks. The selected duration updates before you render so you know exactly what will be kept.
Private by design
