🖼️ MGC - Metadata Gallery Converter

MGC is a lightweight, portable app with a simple goal:
Make it easy to view, edit, and convert metadata from .png images generated by ComfyUI, Stable Diffusion, or TensorART—and make it all play nice with Civitai.

🔒 Update!

If your antivirus flags it as a false positive, don’t worry—it’s because I used auto-py-to-exe to package everything neatly and hide a bunch of Python folders.
I'm currently waiting for the digital signature.
And yes—it's open source. You can also find the version on my GitHub, or just check the included files in the article.

💡 Tip: If you prefer not to run it on your PC, try the Google Colab version. It's simpler, runs in your browser, and works just as well.

🎯 Why I Made This

Honestly, I was just tired of copying prompts manually.
When uploading images from TensorART to Civitai, the metadata often goes missing—even if Tiefsee can read it, retyping everything was a pain.

So I built MGC to fix that.

With it, you can:

Browse your images in a gallery view
Instantly see all prompts and settings
Copy, edit, and save them however you want
Export them in a Civitai-compatible format

🛠️ Key Features

✅ Thumbnail gallery (just drop a folder or drag in images)
✅ Supports .png, .jpg, .jpeg, and .webp
✅ Quick navigation with ↑ and ↓ keys
✅ Clearly shows:
- Positive & Negative Prompts
- Steps, Sampler, Seed, Model, etc.
✅ One-click “Copy All”
✅ Convert to Civitai format instantly
✅ Save prompts as .txt or embed them back into .png
✅ Language toggle (English & Spanish)
✅ Alerts you if metadata is missing (especially for .jpg)

📦 How to Use It

Extract the .zip wherever you like (even a USB stick).
Run MGC_byAGGA.exe.
Drop a folder or open one with the 📂 button.
Click a thumbnail or use the arrows.
That’s it — the metadata shows up automatically.

From there, you can:

Copy or edit the prompts
Save them as .txt
Save them as .png with fixed metadata
Convert them to Civitai format

ℹ️ Requirements

Works on Windows 8 or newer
Doesn’t need installation
Doesn’t need internet
Just works 🙂

🧪 Still Improving

This app is still growing.
If you find a weird image format, or have ideas for features you’d love to see, feel free to share them.
I made this for myself… but also for you, if you’re tired of redoing the same steps every time. 😅

Who just wanted his prompts back.
