# Upscale

> Boost an image or video up to 4× its resolution with AI, without leaving the canvas.

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>;
};

Upscale enlarges the connected image — or video — up to 4× with AI, recovering detail instead of stretching pixels. It runs as a background job, so you can keep working while it processes.

<DemoVideo src="/videos/canvas/image-tools-upscale.mp4" poster="/images/posters/canvas/image-tools-upscale.jpg" caption="Attaching an Upscale tool to an image and choosing the 2× or 4× factor" />

## Using it

Right-click an image or video node, choose **Tools → Upscale**, and a connected Upscale node appears beside it. Then:

* Pick the **Factor** — **2×** or **4×**.
* For images, optionally turn on **Face fix** and set its **Strength** (0–1) to enhance faces during the upscale.
* Press **Upscale**. The node shows *Processing…* and swaps in the result when the job finishes.

The source node is untouched; the upscaled version is the tool node's output. Wire it downstream, or click **Add result as node** to break it out as a standalone image node.

## Video upscaling

Connect a video node instead of an image and the same tool upscales the clip. The Face fix option applies to images only.

<Tip>
  Make Upscale the last step in an editing chain. Crop, retouch, and color-correct first, then upscale the finished frame — you avoid re-running the slow step every time an earlier edit changes.
