# Remove Background

> Cut the subject out of any image or video automatically — no masking required.

export const DemoVideo = ({src, poster, caption, aspectRatio = "16 / 10", className = ""}) => {
  return <figure className={`not-prose my-6 w-full ${className}`}>
      <div className="overflow-hidden rounded-2xl border border-gray-950/10 bg-gray-100 dark:border-white/10 dark:bg-white/5" style={{
    aspectRatio
  }}>
        <video src={src} poster={poster} loop autoPlay muted playsInline className="h-full w-full object-cover" />
      </div>
      {caption && <figcaption className="mt-2 text-center text-sm text-gray-500 dark:text-gray-400">
          {caption}
        </figcaption>}
    </figure>;
};

Remove Background detects the subject and strips everything behind it — no manual masking. It works on images and on video clips.

<DemoVideo src="/videos/canvas/image-tools-removebg.mp4" poster="/images/posters/canvas/image-tools-removebg.jpg" caption="Attaching Remove Background to an image, with its refine-edges control" />

## Using it

Right-click an image node and choose **Tools → Remove Background**. On the connected tool node, leave **Refine edges** on (it cleans up hair and soft boundaries; turn it off for hard-edged graphics), then press **Remove background**. The job runs in the background and the cutout — subject on a transparent background — lands in the node.

From there, wire the cutout into any downstream node, or click **Add result as node** to break it out as a standalone image node.

## Video background removal

Connect a video node instead and the tool keys the moving subject out of the clip. The subject is rendered against a solid green backdrop, which the canvas preview chroma-keys away automatically — so the node shows a clean transparent clip. **Add result as node** creates a [Flam node](/canvas/nodes/flam) with the keying already applied, ready to composite over other layers.

<Tip>
  Cutouts composite anywhere: drop one onto a generated backdrop with [Inpaint](/canvas/image-tools/inpaint), or wire it into a video node as a clean subject reference.
