Image Upscaler API
Increase image resolution up to 4x with texture-aware enhancement for print, ecommerce, or high-dpi screens.
Image Upscaler
Image Upscaler improves an existing image to a higher resolution while preserving the original content and composition. Provide an image URL, choose a scale, and receive an enhanced image URL.
Highlights
- Image-to-image upscaling: Increase image resolution without changing the subject or layout.
- Scale control: Choose an
outscalevalue from1.0to4.0. - Output format control: Generate
jpeg,png,webp, orjpgoutputs. - Fast sync backend: Requests route to the RealESRGAN sync backend through AtlasCloud Serverless.
Parameters
| Parameter | Required | Description |
|---|---|---|
model | Yes | Use atlascloud/image-upscaler. |
image | Yes | Input image URL. |
outscale | No | Output scale multiplier from 1.0 to 4.0. Default: 1.0; use 2.0 for a standard upscale test. |
output_format | No | Output image format: jpeg, png, webp, or jpg. Default: jpeg. |
Limits
The public API exposes the direct scale control only. Target-resolution, size, pixel-budget, base64 output, and seed fields are intentionally not exposed for this launch.
Use input images that are accessible by URL. Very large inputs may be rejected by the backend before processing.
