Chill Image Save Plus for ComfyUI

An enhanced image save node for ComfyUI that extends the built-in SaveImage node with additional format support, quality control for lossy formats, and optional metadata stripping.

Features

  • Multiple Format Support: Save images in PNG, JPEG, WebP, TIFF, and BMP formats
  • Quality Control: Adjustable quality (1-100) for lossy formats (JPEG, WebP)
  • Metadata Options: Choose to embed or strip metadata (workflow, prompt)
  • Batch Processing: Handles batched images with automatic counter incrementing
  • RGBA Handling: Automatically converts RGBA images to RGB for formats that don't support alpha (JPEG, BMP)

cd ComfyUI/custom_nodes
git clone [email protected]:Megachill/ComfyUI-ChillEasyImageSave.git

Method 2: Manual Download

  2. Extract it to ComfyUI/custom_nodes/
  3. Rename the folder to ComfyUI-ChillEasyImageSave

Dependencies

The node requires Pillow >= 9.0.0 (already included with ComfyUI):

Standard Installation:

pip install -r requirements.txt

ComfyUI Portable (Windows): For ComfyUI Portable installations, use the embedded Python:

../../../python_embeded/python.exe -m pip install -r requirements.txt

Run this command from within the ComfyUI/custom_nodes/ComfyUI-ChillEasyImageSave/ folder.

Parameters

| Parameter | Description | Default | |-----------|-------------|---------| | images | Input image tensor from a node (e.g., VAE Decode, Load Image) | Required | | filename_prefix | Prefix for saved files. Supports subfolders (e.g., "outputs/test") | "Chill" | | format | Output format: png, jpg, webp, tiff, bmp | "png" | | quality | Quality for lossy formats (JPEG, WebP). Range: 1-100 | 95 | | strip_metadata | If true, removes all metadata from output | false |

Format Features

| Format | Quality Control | Alpha Support | Metadata Support | |--------|-----------------|---------------|------------------| | PNG | No | Yes | PNG text chunks | | JPEG | Yes | No (RGB conversion) | EXIF UserComment | | WebP | Yes | Yes | EXIF | | TIFF | No | Yes | TIFF tags | | BMP | No | No (RGB conversion) | None |

Metadata

When strip_metadata is disabled:

  • PNG: Embeds workflow and prompt as PNG text chunks
  • JPEG: Embeds metadata in EXIF UserComment tag
  • WebP: Embeds EXIF data
  • TIFF: Embeds metadata in standard TIFF tags
  • BMP: No metadata support

Example Workflow

See examples/workflow.json for a sample ComfyUI workflow demonstrating the node.

Tips

  • Subfolders: Use / or \ in filename_prefix to save to subdirectories (e.g., "batch1/output")
  • Quality Settings:
    • JPEG: 90-100 for high quality, 75-85 for web use, 50-70 for small file size
    • WebP: Similar to JPEG but generally produces smaller files at equivalent quality
  • Transparency: Use PNG or WebP if you need to preserve alpha channel
  • Maximum Compatibility: Use JPEG for broadest compatibility with other software

Compatibility

  • ComfyUI: Latest version (tested with 2024 builds)
  • Python: 3.10+
  • Pillow: >= 9.0.0
