# Upscale an Image

> Increase the resolution of any image by up to 4x while preserving detail.

Upscale increases the resolution of an image so it looks sharp at larger sizes. Use this when you need a higher-resolution version for print, large displays, or high-DPI screens.

## How to upscale

<Steps>
  <Step title="Select an image on the canvas">
    Click on the image you want to upscale. The selection toolbar appears.
  </Step>

  <Step title="Click Upscale">
    Click the **Upscale** button in the toolbar. A dropdown appears with scale options.
  </Step>

  <Step title="Choose your scale factor">
    Select **1x**, **2x**, **3x**, or **4x**. Higher factors produce larger images but use more credits.
  </Step>

  <Step title="A new image appears">
    The upscaled image appears on the canvas as a new item. The original is preserved.
  </Step>
</Steps>

## Scale factors

| Factor | What it does                           | When to use                              |
| ------ | -------------------------------------- | ---------------------------------------- |
| **1x** | Enhances detail at the same resolution | Sharpening a blurry or compressed image  |
| **2x** | Doubles the resolution                 | Social media, web banners, presentations |
| **3x** | Triples the resolution                 | Print materials, posters                 |
| **4x** | Quadruples the resolution              | Large format printing, high-DPI displays |

<Warning>
  4x upscaling on large images costs significantly more credits than lower factors. The cost scales with the output size in megapixels. Start with 2x and only go to 4x if you need the extra resolution.
</Warning>

## Example use cases

<Prompt description="Upscale a product image for a print catalog">
  I generated a product shot of our coffee bag at standard resolution. Upscale it to 4x so I can use it in our print catalog at 300 DPI.
</Prompt>

<Prompt description="Upscale a logo for a storefront banner">
  Upscale this logo image to 3x. I need it large enough for a 6-foot wide banner for our trade show booth.
</Prompt>

## What you cannot do

* You cannot upscale beyond 4x in a single operation. For higher resolution, upscale to 4x and then upscale the result again.
* You cannot upscale videos. This tool works on images only.
* You cannot choose a custom scale factor. Only 1x, 2x, 3x, and 4x are available.
