Save Image Extended for ComfyUI: Organize Image Exports

Understand the project

Practical overview

Use it when a ComfyUI workflow needs more control over how generated images are named, formatted, grouped, or accompanied by generation records.

ComfyUI users who want generated images grouped into custom folders and subfolders.
Workflow builders who want output filenames to include sampler, model, prompt, or other node-widget values.
Users who want JSON records of generation settings saved alongside image outputs.

Save generated images in a selected format, including PNG, WebP, AVIF, JPEG, JXL, TIFF, GIF, BMP, or JPEG 2000.
Build filename and folder patterns from prefixes, workflow values, delimiters, counters, and date or time formats.
Save job details such as prompts, sampler settings, and loaded models to folder-level or per-image JSON files.
Store metadata in image files where the chosen format and library support it.

Before you choose

The project is a self-hosted ComfyUI extension distributed through a public GitHub repository under the GPL-3.0 license.

Filename and folder patterns can reference node widget values using the documented node-ID and widget-name notation.
The extension supports many output formats, but ComfyUI prompt loading is documented for PNG and WebP only.
The README flags limitations involving lossless WebP loading, JPEG 2000 EXIF data, large WebP and JXL images, and oversized JPEG metadata.
The documented install uses ComfyUI's custom_nodes directory and lists Python image-processing dependencies.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Place the repository in ComfyUI's custom_nodes directory and install the listed Python image dependencies.

An existing ComfyUI installation with access to its custom_nodes directory.
Python and the listed packages: NumPy, Pillow, pillow-avif-plugin, and pillow-jxl-plugin.

Open a terminal inside the custom_nodes folder in the ComfyUI installation.
Clone the repository with the command below.
Documented command
```
git clone https://github.com/audioscavenger/save-image-extended-comfyui
```
Install the listed packages with the command below.
Documented command
```
pip install numpy pillow pillow-avif-plugin pillow-jxl-plugin
```

The repository is placed in ComfyUI's custom_nodes directory and the README-listed Python packages are installed.

The README lists Python 3.10.6, PyTorch 2.5.1+cu124, and a ComfyUI 0.3.12 build as a tested configuration, not a compatibility guarantee.
Installation steps do not document running a workflow or validating the node.
