Remove Stable Diffusion Prompts & Workflows from PNG Images
When you render art with Stable Diffusion (AUTOMATIC1111, Forge, InvokeAI, or ComfyUI), your entire generation recipe is automatically saved inside the PNG file. This includes your positive prompt, negative prompt, seed, sampler, steps, CFG scale, and even your full ComfyUI node graph. 7minti deletes these prompt chunks in seconds, keeping your secret workflows completely private.

A Quick Note On Image Privacy
This tool completely removes the hidden digital label attached to your file (like your camera model, where the photo was taken, and your AI prompt secrets).
Good to know: Removing hidden metadata does not alter the actual drawing or photo pixels. If an AI image has visual characteristics (like hands with extra fingers or AI texture patterns), those are part of the picture itself and cannot be removed without ruining the image. We protect your privacy while keeping your pictures crisp and untouched!

How Our Tool Cleans STABLE DIFFUSION PROMPT FROM PNG
Stable Diffusion WebUI interfaces write directly to the PNG 'parameters' and 'workflow' iTXt/tEXt chunks. Anyone with a basic image viewer or PNG info tool can inspect your image and copy your exact prompt, LoRA trigger words, and checkpoint models. Our tool strips these chunks cleanly without touching your visual pixels.
How Stable Diffusion Writes Metadata to PNGs
Stable Diffusion embeds two massive text blocks inside the PNG container:
- →'parameters' chunk: A multi-line string containing positive prompt, negative prompt, Steps, Sampler, CFG scale, Seed, and Model hash.
- →'workflow' chunk: A serialized JSON string containing your entire ComfyUI node network, model paths, and custom script inputs.
- →Our engine locates and drops these exact chunks, returning a clean PNG with zero prompt traces.
❌ What Gets Cleaned (Deleted)
- •Positive text prompt and negative prompt keywords
- •Seed number, sampler name, steps count, and CFG scale
- •Checkpoint model hash and LoRA configuration strings
- •Complete ComfyUI node workflow graph in JSON format
- •Embedded generation timestamps and software version
✅ What Stays 100% Intact (Preserved)
- •100% original artwork quality and pixel values
- •Exact resolution (512x512, 1024x1024, upscaled)
- •Zero color shift, noise alteration, or blurring
ComfyUI stores every node in your canvas inside the PNG. If you use custom LoRAs or local computer directory paths in your loader nodes, those private file paths can be exposed when sharing the raw PNG. Cleaning the file eliminates this security risk.

Frequently Asked Questions
Unique answers specifically for stable diffusion prompt from PNG.
How do I remove the prompt from a Stable Diffusion PNG?
Drag your PNG into the cleaner above. It automatically detects and removes the 'parameters' and 'workflow' chunks, producing a clean PNG with zero prompt traces.
Can someone copy my ComfyUI workflow from my image?
Yes, standard ComfyUI PNGs save your full node graph. Dragging your image into another person's ComfyUI will load your entire setup unless you clean the metadata first.
