Advanced Image Upscaler API

What it does

Image Upscaler enlarges an image file by 2× or 4× and returns the processed image as a binary file. Send a JPEG, PNG, WebP, or BMP up to 20 MB, and choose whether to use the anime-optimised model variant or run face enhancement on the result.

Use it when you need to prepare product photos for larger displays, improve screenshot readability, or restore low-resolution assets for design and content workflows. The scale field controls the output size, with supported values of 2 and 4. Set anime to true for stylised artwork, or face_enhance to true when portraits or close-up faces need restoration after upscaling.

The response is the upscaled image itself, so it fits cleanly into image pipelines that store, forward, or post-process binary files. That makes Image Upscaler useful in publishing tools, media management systems, and automated asset preparation where you want a larger image without changing the source format manually.
