Yes — completely free, no watermark, no signup, no file limits beyond your device's memory.
No — everything runs on your device in the browser. Your videos never leave your computer.

Crop Video lets you draw and drag a crop region directly on the live preview — trim away letterboxes, focus on a subject or reframe for a different aspect. The pipeline renders only the cropped pixels at full quality.
It's free, private and works right in your browser — no signup, no watermark.
