Three ways to square

Crop-to-fill (position the window anywhere), blurred-background, or a solid color of your choice — whatever suits the footage.

Runs on your hardware

Where your browser supports it (Chrome/Edge/Safari), the work runs on your device's video hardware via WebCodecs — far faster than uploading to a server and waiting in a queue.

  2. 2Choose crop, blur or solid fill and position it.
  3. 3Trim and export the square MP4.

1080×1080 here — the standard for feeds and profiles.
