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
targetsetting 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
| Parameter | Required | Description |
|---|---|---|
| image | Yes | Input image to upscale. |
| target | No | Target upscale setting or output target level. Higher values produce a larger or stronger upscale result. Supports values up to 128. |
| output_format | No | Output image format, such as png. |
How to Use
- Upload your image — provide the source image you want to enhance.
- Choose the target — select the upscale target that best matches your quality needs.
- Choose output format (optional) — select the format that best fits your workflow.
- 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.
| Target | Cost |
|---|---|
<= 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 <= 4cost $0.005 per image - Requests with
target > 4and<= 8cost $0.010 per image - Requests with
target > 8and<= 16cost $0.020 per image - Requests with
target > 16and<= 32cost $0.040 per image - Requests with
target > 32and<= 64cost $0.060 per image - Requests with
target > 64and<= 128cost $0.120 per image - Pricing depends on the selected
target output_formatdoes 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
targetsetting first if you want a faster and cheaper test run. - Use a clean source image whenever possible for better enhancement results.
- Choose a higher
targetonly when you actually need the larger or stronger upscale output. pngis a good choice when you want to preserve output quality.
Notes
imageis the only required field.targetnow supports values up to 128.- Pricing depends on the selected
targettier. output_formatchanges the file type, but not the price.- Higher target values may be more suitable for print, detailed review, or premium delivery workflows.

Task Submission Parameters
Request Parameters
| Parameter | Type | Required | Default | Range | Description |
|---|---|---|---|---|---|
| image | string | Yes | - | Input image URL. | |
| target | integer | No | 4 | 1 ~ 128 | Target output size in megapixels. |
| output_format | string | No | png | png, jpg, webp | Output image format. |
| enable_sync_mode | boolean | No | false | - | 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_output | boolean | No | false | - | 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. |
