Pruna AI P-Image Upscale is a fast AI image upscaling model that enhances image resolution and improves visual detail. Ready-to-use REST inference API for product photos, portraits, design assets, e-commerce images, social media visuals, and image enhancement workflows with simple integration, no coldstarts, and affordable pricing.

Features

Pruna AI P-Image Upscale enhances and enlarges images with a simple workflow built around target size selection and flexible output formatting. It is suitable for restoring old images, improving low-resolution assets, preparing sharper visuals for design or marketing, and generating cleaner outputs for downstream use.


Why Choose This?

  • Simple image upscaling Upload a single image and generate a higher-quality result with minimal configuration.

  • Target-based output control Use the target setting to choose the desired upscale level or output target.

  • Clean enhancement workflow Improve image clarity for photos, scans, product images, and other visual assets.

  • Flexible output format Export the upscaled image in a supported format such as png.

  • Affordable tiered pricing Uses a simple pricing structure based on the selected target tier.


Parameters

ParameterRequiredDescription
imageYesInput image to upscale.
targetNoTarget upscale setting or output target level. Higher values produce a larger or stronger upscale result. Supports values up to 128.
output_formatNoOutput image format, such as png.

How to Use

  1. Upload your image — provide the source image you want to enhance.
  2. Choose the target — select the upscale target that best matches your quality needs.
  3. Choose output format (optional) — select the format that best fits your workflow.
  4. Submit — run the model and download the upscaled image.

Example Use Case

Upscale an old street photograph to produce a cleaner, sharper version for archival, presentation, or creative reuse.


Pricing

Pricing is based on the selected target tier.

TargetCost
<= 4$0.005
> 4 and <= 8$0.010
> 8 and <= 16$0.020
> 16 and <= 32$0.040
> 32 and <= 64$0.060
> 64 and <= 128$0.120

Billing Rules

  • Requests with target <= 4 cost $0.005 per image
  • Requests with target > 4 and <= 8 cost $0.010 per image
  • Requests with target > 8 and <= 16 cost $0.020 per image
  • Requests with target > 16 and <= 32 cost $0.040 per image
  • Requests with target > 32 and <= 64 cost $0.060 per image
  • Requests with target > 64 and <= 128 cost $0.120 per image
  • Pricing depends on the selected target
  • output_format does not affect pricing

Best Use Cases

  • Old photo enhancement — Improve the clarity of scanned or low-resolution photographs.
  • Design asset preparation — Create sharper source images for layouts, presentations, and creative projects.
  • Product image improvement — Upscale commercial visuals for catalogs, ads, and marketplace listings.
  • Archival restoration workflows — Produce cleaner and larger outputs from legacy image assets.
  • General low-resolution cleanup — Improve images that need a simple boost in size and quality.

Pro Tips

  • Start with a lower target setting first if you want a faster and cheaper test run.
  • Use a clean source image whenever possible for better enhancement results.
  • Choose a higher target only when you actually need the larger or stronger upscale output.
  • png is a good choice when you want to preserve output quality.

Notes

  • image is the only required field.
  • target now supports values up to 128.
  • Pricing depends on the selected target tier.
  • output_format changes the file type, but not the price.
  • Higher target values may be more suitable for print, detailed review, or premium delivery workflows.

Parameters

Task Submission Parameters

Request Parameters

ParameterTypeRequiredDefaultRangeDescription
imagestringYes-Input image URL.
targetintegerNo41 ~ 128Target output size in megapixels.
output_formatstringNopngpng, jpg, webpOutput image format.
enable_sync_modebooleanNofalse-If set to `true`, the request attempts to wait for the generated result and return outputs in the same response. If the result is not ready within the sync wait window, the API can return a timeout body while the task continues processing. This option is only available via the API and is supported only by some models.
enable_base64_outputbooleanNofalse-If set to `true`, the prediction's `output` strings are returned as **naked base64** (no `data:<mime>;base64,` prefix). When `false` (default), outputs are returned as URLs pointing to our CDN.
