How to use Video Cropper
- Choose a video file.
- Enter the crop area: left, top, width and height in pixels.
- Click Process Video to re-record the cropped area.
- Download the cropped video.
Honest limit: the cropped video is re-recorded to WebM in your browser (browsers cannot natively re-encode MP4), so output is a .webm file.
Frequently Asked Questions
Is the Video Cropper free?
Yes, it is 100% free with no sign-up. Your files and data stay in your browser.
