🧹 Remove Metadata for ComfyUI
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, andzTXtchunks - ✅ Removes AI generation comments
- ✅ Works with batch images
- ✅ No visible quality loss
- ✅ Fully offline & local
📂 Installation
- Navigate to your ComfyUI installation:
cd ComfyUI/custom_nodes
- Clone or create the node folder:
git clone https://github.com/yourname/remove-metadata-comfyui.git
- 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
