Generation parameters
A text chunk may contain positive and negative prompts, seed, sampler, steps and CFG settings.
Stable Diffusion / PNG Info
Remove Stable Diffusion prompt metadata
Inspect PNG Info, EXIF, XMP and C2PA for prompts, seeds, model details and generation settings. Export a clean local copy without the sections you select.
CONTEXT / EVIDENCE
The interface writes metadata, not the model alone
Stable Diffusion is a model family; the application that saves the image decides which fields travel with it. AUTOMATIC1111 documents that its PNG Info feature adds generation parameters to a PNG text chunk so they can be restored later.
Those parameters can include a prompt, negative prompt, seed, sampler, steps, CFG and model details. Other interfaces and export formats use different fields, so ClearTags inspects the file before offering selective cleanup.
What may be exposed
C2PA · EXIF · XMP · CONTAINERModel and workflow details
Model hashes, LoRA names, software versions or local naming conventions can reveal a production setup.
Exporter behavior
A different Stable Diffusion UI, extension or JPEG/WebP export may store less, more or no readable generation metadata.
Clean Stable Diffusion PNG Info
WORKFLOW / LOCAL COPY- 01
Choose the publishing copy
Inspect the final image after upscaling, retouching and format conversion.
- 02
Review parameters
Look for prompt, negative prompt, seed, model, PNG text, EXIF, XMP and C2PA.
- 03
Remove prompt-bearing sections
For a supported PNG, remove comments and text fields while preserving the encoded image data.
- 04
Verify the output
Inspect the clean derivative again and keep the parameter-rich original privately if you need reproducibility.
