Remove ComfyUI & Stable Diffusion Metadata
ComfyUI saves the full node graph into a PNG under a "workflow" key, and Automatic1111 saves the prompt, seed, sampler and model under "parameters". This tool removes those embedded generation traces so a shared image no longer carries your recipe. It strips the data embedded in the file; it does not alter pixels. Processed locally in your browser - nothing is uploaded.
What gets removed
Post a generated PNG straight from ComfyUI and anyone can load it back in and see your exact workflow, custom nodes, LoRAs and prompt. That is a full disclosure of how you made the image. Removing the workflow and parameters chunks keeps the picture and drops the recipe - without touching a single pixel.
- ComfyUI "workflow" node graph
- ComfyUI / A1111 "prompt" and "parameters"
- Prompt, negative prompt, seed and sampler settings
- Model, LoRA and custom-node references
- Other embedded text chunks
Frequently Asked Questions
About stripping EXIF, GPS, AI workflow data and other embedded metadata.
No, and it does not claim to. It removes the AI generation data embedded in the file (the ComfyUI workflow, the A1111 parameters, a C2PA tag). It does not analyze or change the pixels, so a separate pixel-based AI detector is unaffected.
No. The workflow is metadata, not pixels. After removal the PNG looks identical; it just no longer carries the generation recipe.
