Image Upscaler

Image UpscalingUp to 8KSingle Image

Image Upscaler is APIXO’s single-image enhancement tool for increasing image resolution to 2K, 4K, or 8K. Upload one source image, choose the target resolution and output format, then receive a higher-resolution JPG, PNG, or WEBP through an asynchronous task.

Capabilities

Straightforward image upscaling for production workflows

2K, 4K & 8K Output

Choose the resolution level that fits the final asset, from lightweight 2K enhancement to higher-resolution 4K and 8K output.

Single-Image Workflow

Submit exactly one source image per task for a focused enhancement workflow without additional reference images or prompt configuration.

Flexible Output Formats

Export the enhanced result as JPG, PNG, or WEBP to match downstream web, design, ecommerce, or asset-pipeline requirements.

Simple Resolution Control

Set the target resolution directly instead of managing scale factors or complex enhancement parameters. APIXO defaults to 4K when no resolution is specified.

Async Processing

Submit enhancement jobs asynchronously and poll task status until the processed image is ready.

Callback Delivery

Use a public HTTPS callback URL to receive the task result automatically when the enhanced image is ready.

Quick Start

Upscale an image in three steps

Move from a source image to a higher-resolution asset with minimal configuration.

Provide the source image

Submit one publicly accessible image URL as the source asset for the enhancement task.

Choose resolution and format

Select 2K, 4K, or 8K output and choose JPG, PNG, or WEBP. If omitted, APIXO uses 4K and JPG by default.

Retrieve the enhanced image

Poll the task status asynchronously or provide a callback URL to receive the result when processing completes.

Notes & FAQ

Image Upscaler generation guidance

Notes

Each task requires exactly one source image.

The source image URL must be public and directly accessible by the service.

Available target resolutions are 2K, 4K, and 8K, with 4K used by default.

Output formats include JPG, PNG, and WEBP. JPEG aliases are normalized to JPG.

Upscaling can improve resolution and visible detail, but it cannot reliably recover information that is completely absent from the source image.

Heavily compressed, blurred, or low-quality source images may still contain visible artifacts after enhancement.

Frequently Asked Questions

APIXO currently supports 2K, 4K, and 8K output. If no resolution is specified, the task defaults to 4K.

Each task accepts exactly one source image URL. Submit separate tasks when processing multiple images.

You can export the enhanced result as JPG, PNG, or WEBP. JPG is the default output format.

Upscaling can enhance resolution and visible detail, but it cannot guarantee recovery of information that is completely missing from the original image.

Yes. You can poll an asynchronous task or use callback mode with a public HTTPS URL to receive the result when processing completes.
