What is a ComfyUI Workflow Extractor?
When you generate an image using ComfyUI, the software secretly saves your entire “recipe” inside the PNG image file. This recipe includes:
- The Workflow: The exact visual layout of all the nodes you used.
- The Prompt: The execution data that tells the AI exactly what to do.
Our extractor tool reads the hidden text inside your image, finds this data, and pulls it out for you. It turns a regular picture back into a reusable AI workflow.
Why Use Our Tool?
- 100% Private and Secure: Your images are never uploaded to a server. The extraction happens entirely inside your own web browser, meaning your data stays strictly on your computer.
- No Installation Required: You don’t need to install Python, custom nodes, or any extra software. Just open the page and use it.
- Download as JSON: With one click, you can download the extracted data as a
.jsonfile, ready to be dragged and dropped directly into your ComfyUI workspace. - Lightning Fast: Because it runs locally on your device, the extraction happens instantly.

Frequently Asked Questions (FAQ)
Why does the tool say “No workflow data found”?
If our tool cannot find the workflow, it usually means the image’s metadata was removed. When you upload images to social media sites like Discord, Reddit, or WhatsApp, they automatically compress the image and delete the hidden text to save space. Always use the original PNG file saved directly from ComfyUI.
Does this work with Automatic1111 or WebUI images?
No. This specific tool is designed only to read the unique TEXT chunks used by ComfyUI. Other interfaces save their data differently.
Can I use this on my mobile phone?
Yes! Because it is a simple web tool, you can use it on your smartphone, tablet, or desktop computer. Just select an image from your phone’s gallery.
Is the tool free?
Yes, this tool is 100% free to use with no limits.
