Upload a video file, drag the rectangle over the area you want to keep, and crop. Cropping re-encodes the video, so longer files take a while.
Your file never leaves your device. All processing happens right in your browser, and nothing is uploaded to a server.
Select the rectangle you want to keep and the tool re-encodes only that region into a new video. Everything outside the crop disappears, and the output resolution becomes the crop size.
Black bars baked into downloads, a neighbor wandering into frame, sensitive screen regions in recordings, letterboxed phone footage, and reframing wide shots for square or vertical destinations.
