How It Works

Step 1Will your subject fit in a square?
Step 2Create your square copy

Will your subject fit in a square?

Look at the shape you are starting with. A wide video loses space at the sides when you make it square; a tall video can lose space above and below the subject. For example, check both a product and the label beneath it if they need to stay together in the shot.

This tool uses a centered crop. There is no Fit Mode menu in this workspace to switch to a blurred background or black bars. If the crop removes something you need, keep the original and reframe the shot before using this tool.

Create your square copy

Open one video

Open one MP4, WebM, MOV, AVI or MKV file, up to 500 MB. Check the processing options offered for that file: your device may have a lower limit for local processing.

Keep the resize defaults

For a basic resize, leave the effects unchanged. In Output, keep MP4 selected and Resolution at Original. You do not need to enter 1080 × 1080 yourself; this tool supplies that target size.

Process and save the result

Click Process Resize Video to Square. Once the result downloads, play the saved copy from start to finish. Check the top, bottom and sides as the subject moves. Keep your source video so you can return to the wider or taller shot if the square version leaves out too much.

Questions about square resizing

This tool uses a centered crop and has no padding option. Watch both people throughout the saved clip. If either is cut off, keep the original and use an editor with padding or custom framing before making a square version.
