## What it is
A Stable Diffusion WebUI (Automatic1111) plugin that integrates StableSR, a diffusion-prior-based super-resolution method, for high-fidelity image upscaling. It preserves face identity and detail while using less VRAM than alternatives like ControlNet Tile.

## Use cases
- upscale low-resolution images to high resolution
- enhance details in AI-generated images
- restore old or blurry photos with stable diffusion
- upscale anime and realistic images without losing face identity
- super-resolution inside automatic1111 webui
- enlarge 128x128 images to 1024x1024

## When to choose
- you already use Automatic1111 WebUI and want built-in high-quality upscaling
- you need detail-preserving upscaling of faces or AIGC images with low VRAM usage

## When to avoid
- you use ComfyUI or another UI without Automatic1111
- you need a standalone command-line upscaler or a non-Stable-Diffusion pipeline
- you require a permissive license, since S-Lab License 1.0 restricts commercial use
