2 Set the start and end time for the section you want to keep.
3 Export the selected range as a clean MP4.

FAQ

Is my video uploaded anywhere?

No. The assembly work runs in your browser with WebAssembly, so the selected files stay on your device.

Why can export take a while?

The browser needs to decode and re-encode the video locally. Keep this tab open until the export finishes.

Does the tool add a watermark?

No. The exported MP4 is watermark-free.

Can this cut precisely?

Yes. The tool re-encodes the selected range so cuts can land near exact timestamps.
