# 🧹 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`, 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:
```bash
cd ComfyUI/custom_nodes
```
2. Clone or create the node folder:
```bash
git clone https://github.com/yourname/remove-metadata-comfyui.git
```
3. 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
