How to use it

Add a video and move the crop frame directly on the preview. You can use free crop or 9:16, 1:1 and 16:9 presets.

Use 9:16 for vertical clips, 1:1 for square posts and 16:9 for regular video. Exact percentages are available below the preview.

Your files are not uploaded to a server. The editor runs in your browser with local libraries from this site.

Large images can take longer on phones. If the browser slows down, process fewer files at once or choose a smaller output format.
