What is Video Cropper?
The Video Cropper cuts a selected region out of any video your browser can play. Drag the crop box over the preview or enter exact pixel coordinates, choose a quality preset, and the tool re-records the clip through a canvas with MediaRecorder - producing a cropped WebM without uploading anything.

Frequently Asked Questions
Why does cropping take as long as the video?
The crop is re-recorded in real time through canvas and MediaRecorder, which needs no server. A one-minute clip takes about one minute - keep the tab in the foreground while it runs.
Why is the output WebM and not MP4?
Browsers can encode WebM (VP9/VP8) natively via MediaRecorder, but not H.264. WebM plays in all modern browsers and converts to MP4 easily with ffmpeg if you need it.
Is the original audio kept?
When the browser allows audio capture, the original audio is passed through to the new file. If capture is unavailable, the output is video-only.
Is my video uploaded anywhere?
No. The video is read locally, drawn to a canvas, and re-recorded in your browser. Nothing ever touches a server.
