How Stable Diffusion marks images
Automatic1111 and related Stable Diffusion web interfaces store generation parameters in PNG `parameters` tEXt and zTXt chunks.
What gets embedded in the file
Positive prompt, negative prompt, steps, sampler name, CFG scale, seed, model checkpoint hash, and LoRA references.
Lossless cleaning method
Directly filters out `parameters` and ancillary text chunks while copying IDAT image data bit-for-bit.
Technical limits and policy
Pure metadata removal. Pixel data is completely unchanged.
How to Clean Stable Diffusion Images
Add your Stable Diffusion file
Drag and drop your JPEG, PNG, or WebP image into Clean on your desktop or mobile browser.
Select your preset
Choose "Remove AI markers only" to drop generation manifests while keeping color profiles and EXIF.
Download clean image
Download your cleaned image with bit-identical pixel data and no embedded generator flags.
Stable Diffusion Metadata FAQs
What metadata does Stable Diffusion add to image files?
Stable Diffusion embeds provenance records, generator tags, and parameter metadata into file headers upon creation or export.
How does Clean remove metadata from Stable Diffusion images?
Clean parses the file format structure in your browser and drops unwanted metadata blocks without re-compressing image pixels.
Does cleaning Stable Diffusion files degrade visual quality?
No. Clean operates at the binary level and copies compressed image bytes verbatim, ensuring 100% lossless output.
