ComfyUI Clean Image Metadata

A tiny ComfyUI custom node that saves images without ComfyUI prompt/workflow metadata.

It is useful when you want to share an output image without embedding the workflow, prompt, or extra ComfyUI PNG info.

Node

• Save Image Without Metadata

Install

Clone this repository into your ComfyUI custom nodes folder:

cd C:\Users\Administrator\Documents\ComfyUI\custom_nodes
git clone https://github.com/cp199712138-design/ComfyUI-CleanImageMetadata.git

Restart ComfyUI, then search for:

Save Image Without Metadata

Usage

Use it as a replacement for ComfyUI's built-in Save Image node.

Connect your image output to images, then run the workflow. The saved file will not include ComfyUI prompt/workflow metadata.

Parameters

• filename_prefix: Output filename prefix. This only affects the filename and is not written into image metadata.
• format: Recommended default is PNG. PNG is lossless and does not reduce image quality. JPEG is lossy and can reduce quality.
• png_compress_level: Recommended default is 4. This only affects file size and save speed, not image quality. 0 is fastest and largest; 9 is smallest and slower.
• jpeg_quality: Recommended default is 100. JPEG is still a lossy format; higher values are closer to the original image but create larger files.

Notes

• No extra pip dependencies.
• Does not modify ComfyUI's built-in Save Image node.
• Does not remove visible watermarks or anything baked into pixels.
• Supports PNG and JPEG.
