- Context Menu Integration: Right-click any node with an image and select "🖼️miniPaint".

input/miniPaintfolder. - Auto-Update: After saving in the editor, the
Load Imagenode in ComfyUI automatically updates to the new file. - Smart Tabs: Uses a single browser tab for all editing sessions to prevent clutter.
- Fully Offline: No external servers involved, all processing is local.
Installation
- Clone this repo into your
ComfyUI/custom_nodes/folder. - Restart ComfyUI.
Usage
- Right-click on a Load Image or similar node , select 🖼️miniPaint choose one of the following options:
Edit in miniPaint (New Window)
Opens the miniPaint editor in a separate browser window. Best for users who prefer a dedicated workspace with more screen space.
Edit in miniPaint (Pop-up)
- Opens the miniPaint editor as a pop-up within ComfyUI's interface.
- Ideal for quick edits without leaving the ComfyUI workflow.
Editing Workflow (Both Modes)
- Edit your image in the chosen editor tab.
- Click the blue "SAVE TO COMFY" button at the top of the editor.
- The file will appear in input/miniPaint/ and auto-load into your node.
- Close the tab when finished.
Important Notes
- Same Browser Only: The "Edit" and "Save" functions only work if the editor is opened in the same browser where ComfyUI is running. If you copy the editor URL to a different browser, the link between them will be lost.
- Single Tab: The extension is designed to use a single browser tab for editing. If you have multiple editor tabs open manually, only the one linked to the current session will receive images.
