Simple Video Cutter

Most "free" video cutters online either stamp an ugly watermark across your clip, push you into a $20/month subscription after the first export, or quietly upload your family videos to a processing server. We built this cutter because cutting a 30-second clip out of a video should not require an account, a credit card, or trusting a stranger's cloud. Everything runs on your own device using the same hardware-accelerated WebCodecs engine your browser uses to play video.

How it works: 1) Drop your MP4, WebM, MOV, or MKV file — it never leaves your browser. 2) Drag the two handles to pick the start and end of the segment you want to keep, and fine-tune with the numeric fields. 3) Click Cut, and the trimmed MP4 (or WebM) downloads instantly — full quality, no watermark. Optionally, extract just the audio of your selection as an MP3 in the same pass.

Your browser's built-in video decoder and encoder do all the work (WebCodecs), so cutting is fast even on long files. If your device does not expose a hardware encoder, the tool automatically falls back to a software encoder — the result is the same, just a little slower.
