Video Cropper

Summary

Load a video, drag a crop rectangle on the canvas overlay, then record and download the cropped region as a WebM file — entirely in your browser.

How it works

1. Click "Choose Video" to load an MP4, WebM, or MOV file from your device.
2. The video appears on a canvas with a crop rectangle drawn over it.
3. Drag any corner handle to resize the crop area, or drag the center to reposition it.
4. The live preview canvas on the right shows exactly what will be captured.
5. Click "Record Crop" to play the video and capture the cropped region.
6. When the video ends (or you click Stop), download the cropped WebM file.
