Image Upscaler is the Nodespell Creative Tool for making an image larger while improving its detail. You give it one image, choose a model and a scale factor, and select Upscale. The result is a new, larger image take; the source image is not changed. You can upscale any image from your Assets or continue directly from an image result.
When should I use Image Upscaler?
Section titled “When should I use Image Upscaler?”Use Image Upscaler when the picture is right but too small or too soft for its final use.

Upscale an image
Section titled “Upscale an image”- Open Create and select Image Upscaler in the tool rail.
- Check the model card. The default model is Crystal Upscaler.

Continue from a result
Section titled “Continue from a result”After any image result in Create, select Continue with this result and choose Image Upscaler. Nodespell keeps that exact result as a visible Asset node named “Selected historical result”, connects it to the upscaler’s source input, and opens the Image Upscaler composer. A notice says “This tool will use the exact selected result through a visible Asset node.” Select Remove to drop that source and pick another. Nothing runs until you select Upscale.
Image Upscaler inputs and controls
Section titled “Image Upscaler inputs and controls”| Control | What it does | Options or default |
|---|---|---|
| Model card | Chooses the upscaling model | Default Crystal Upscaler |
| Source image | The image to enlarge | Required, one image |
| More settings | Any other setting the model has | Collapsed when present |

Which models work with Image Upscaler?
Section titled “Which models work with Image Upscaler?”The picker shows these under Featured:
- Crystal Upscaler (default), tuned for portraits and faces
- Clarity Pro Upscaler
- Google Upscaler
All models also lists Bria Increase Resolution, P Image Upscale, Qwen Image Edit Upscale, Recraft Crisp Upscale, and SeedVR Upscale Image.
How do the controls change with the model?
Section titled “How do the controls change with the model?”With Crystal Upscaler, the main control is Scale factor, from 1 to 6 with a default of 2. A scale factor of 2 doubles the width and height. Other upscalers use their own controls, such as an upscale factor or a target size. The picker’s fact badges show each model’s upscale range before you switch.
Credit estimates for upscalers often depend on the size of the input image, so the estimate may read Varies until the image is known.
Where does the upscaled image go?
Section titled “Where does the upscaled image go?”Selecting Upscale adds a model node to the current Level of your graph and runs it. The larger image is kept as a take on that node and shown in Results. Use View fullscreen to check detail at full size.
Common problems
Section titled “Common problems”| Problem | What to do |
|---|---|
| “This value is required.” on Source image | Add an image or connect one before you select Upscale. |
| Added detail looks wrong | AI upscalers add detail that was not in the source. Try a lower scale factor or a different model. |
| “The saved source is no longer available.” | The result you continued from is gone. Select Remove and choose another image. |
