ComfyUI Extension: Save Image Extended for ComfyUI

Save Image Extended for ComfyUI Introduction

The save-image-extended-comfyui extension is a powerful tool designed to enhance your experience with ComfyUI by providing advanced options for saving your generated images. This extension allows you to save images in various formats such as JXL, AVIF, WebP, JPEG, JPEG2k, PNG, GIF, TIFF, and BMP. Additionally, it offers extensive customization options for organizing your images into folders and sub-folders, and for naming your files based on various parameters.

For AI artists, this means you can keep your work organized and easily accessible, with filenames and folder structures that reflect the details of your creative process. This can be particularly useful for tracking different versions of your work, comparing results from different models or settings, and sharing your work with others in a clear and structured way.

How Save Image Extended for ComfyUI Works

The extension works by integrating with ComfyUI to intercept the image-saving process. It allows you to define custom rules for how and where your images are saved. You can specify prefixes for filenames and folder names, include various parameters in the names, and even save additional metadata about each image in a JSON file.

Think of it as a highly customizable filing system for your images. Instead of manually renaming and organizing your files, you set up rules once, and the extension takes care of the rest. For example, you can automatically include the date, the model used, and specific settings in the filename, making it easy to identify each image at a glance.
