# TopazImageEnhance - ComfyUI Built-in Node Documentation

> Complete documentation for the TopazImageEnhance node in ComfyUI. Learn its inputs, outputs, parameters and usage.

The Topaz Image Enhance node provides industry-standard upscaling and image enhancement. It processes a single input image using a cloud-based AI model to improve quality, detail, and resolution. The node offers fine-grained control over the enhancement process, including options for creative guidance, subject focus, and facial preservation.
