# Image Upscaling

Image Upscaling increases the resolution and detail of an existing image without regenerating it from scratch. Use it to prepare images for print, large-format display, or any output format that requires higher pixel density than the original generation.

***

#### What Upscaling Does

Upscaling processes your image and produces a higher-resolution version with enhanced detail and sharpness. It increases the pixel dimensions of the image by the selected multiplier — 2x, 3x, or 4x — while preserving the composition, subject, and overall visual of the original.

Upscaling improves **resolution and clarity** — it does not alter composition, change subjects, or fix structural issues in the original image. If the composition or content needs changing, use Image Inpainting → or regenerate with a refined prompt.

***

#### How to Use Upscaling

* **Step 1 —** Open **Image Editing → Upscale** from the workspace.
* **Step 2 —** Upload the image you want to upscale, or select one from your generation history.
* **Step 3 —** Select your upscale multiplier — **2x**, **3x**, or **4x**.
* **Step 4 —** Review the credit cost displayed before generating.
* **Step 5 —** Click **Generate**. The upscaled image is produced and saved to your history.

#### Upscale Options

| Multiplier | Use Case                                                                                         |
| ---------- | ------------------------------------------------------------------------------------------------ |
| **2x**     | Standard quality improvement — digital publishing, high-resolution social media, client previews |
| **3x**     | High-quality print preparation — brochures, posters, A3 and A4 print formats                     |
| **4x**     | Maximum resolution — large-format print, billboard, exhibition display, commercial production    |

#### When to Upscale vs. Regenerate at Higher Quality

Upscaling is the right choice when:

* Your prompt, composition, and subject are exactly right and you only need higher resolution
* You generated at 1K or 720p during testing and need the confirmed output at print quality
* You want to avoid spending credits on a full regeneration when only resolution needs improving

Regenerating at higher quality makes more sense when:

* The original image has structural issues, artifacts, or composition problems
* You want the model to add more detail during generation rather than after
* The subject or scene needs refinement alongside the resolution increase
