🧹 Remove Metadata for ComfyUI

Version ComfyUI License

A lightweight custom ComfyUI node that removes all metadata from images (EXIF, PNG text chunks, AI generation info) while keeping the image visually unchanged.

Perfect for:

  • Cleaning AI-generated images
  • Privacy‑focused workflows
  • Preparing images for upload, sharing, or datasets
  • Avoiding unwanted metadata leaks

✨ Features

  • ✅ Removes EXIF metadata (camera, software, GPS, etc.)
  • ✅ Strips PNG tEXt, iTXt, and zTXt chunks
  • ✅ Removes AI generation comments
  • ✅ Works with batch images
  • ✅ No visible quality loss
  • ✅ Fully offline & local

📂 Installation

  1. Navigate to your ComfyUI installation:
cd ComfyUI/custom_nodes
  1. Clone or create the node folder:
git clone https://github.com/yourname/remove-metadata-comfyui.git
  1. Restart ComfyUI

🧩 Node Location

After restart, find the node at:

Image → Utils → Remove Image Metadata

🔌 Usage

Basic workflow:

Load Image
   ↓
Remove Image Metadata
   ↓
Save Image
  • Input: IMAGE
  • Output: IMAGE (cleaned, metadata‑free)

The output image will look identical, but all metadata is removed.

🧠 How It Works

  • Converts ComfyUI image tensors to PIL images
  • Re‑encodes images without metadata
  • Returns clean tensors back to ComfyUI

No pixel manipulation, only metadata sanitization.

⚠️ Notes

  • Color profile (ICC) is currently removed
  • PNG output format is used internally
  • Original filename metadata is not preserved

🚀 Planned Enhancements

  • 🔘 Toggle: keep/remove ICC color profile
  • 🗂 Batch filename suffix (_clean)
  • 📸 JPEG / PNG format selector
  • 🛰 Optional GPS spoof node (separate module)
  • 🛡 Extra‑stealth recompression mode
