Video cropper

Crop a rectangle out of a video in the browser with an aspect preset or freeform box and download the re-encoded result.

Open a video and draw the region you want to keep
The preview decodes what the browser already plays, the crop box clamps to the frame, and the export re-encodes only the selected rectangle. Nothing is uploaded.

Cropping always re-encodes; there is no stream copy and no lossless crop here, so expect some quality loss and a wait proportional to the clip's length. The export plays the clip once and records the selected rectangle through MediaRecorder, so the container follows your browser (usually WebM, MP4 where the browser can encode it). Source pixels are never uploaded; everything decodes and encodes in this tab.
