Short answer:: AUTOMATIC1111 and ComfyUI save the full prompt, negative prompt, seed, sampler and model in a PNG text chunk (keyword 'parameters', or a ComfyUI 'workflow'). AI Remover Pro rewrites the PNG without those chunks, in your browser, so your prompt and settings aren't shared.

Visual guide for Remove Stable Diffusion & ComfyUI metadata, showing the local browser workflow — The Remove Stable Diffusion & ComfyUI metadata tool follows the workflow above in AI Remover Pro.

What Stable Diffusion metadata can contain

A Stable Diffusion PNG may expose the positive and negative prompt, seed, sampler, step count, CFG scale, checkpoint, VAE and image dimensions. ComfyUI can also store the complete node graph in workflow and prompt chunks.

Remove parameters without re-encoding the PNG

This Stable Diffusion metadata remover removes supported PNG text and provenance chunks without redrawing the image. The output is read again so the receipt can report whether parameters or workflow data remain.

Inspect the workflow before deleting it

Generation settings can be useful when you want to reproduce an image. Use the image metadata viewer first, save any prompt or workflow you still need, then clean the shareable copy.

Frequently asked questions

What Stable Diffusion metadata can be stored in a PNG?

A PNG can contain prompts, seed, sampler, steps, CFG scale, checkpoint, VAE and dimensions. ComfyUI may also store its prompt and workflow graph.

Does cleaning Stable Diffusion metadata change the image?

The supported metadata chunks are removed without redrawing or recompressing the visible PNG pixels.

Can I inspect the prompt before removing it?

Yes. Open the metadata viewer first and save any prompt, seed or workflow you still need before cleaning the shareable copy.

Does this remove invisible pixel watermarks?

No. Pixel-level marks such as SynthID are not Stable Diffusion metadata and are outside a metadata cleaner's scope.

Can it remove ComfyUI workflow metadata?

It removes supported ComfyUI prompt and workflow chunks and then reads the output again to report the result.
