Remove prompts and workflows from AI images

Make a clean copy of a PNG or JPEG without the Stable Diffusion prompt, seed, ComfyUI graph or comments — while keeping the Content Credentials and IPTC AI label that marketplaces expect. Works on one image or up to 200 at once (ZIP download). Pixels are untouched and nothing is uploaded.

Recipe out, label in. The clean copy removes prompts, seeds, workflows, comments and EXIF but keeps the IPTC AI label and Content Credentials.

Why keep the AI label?

Protecting your prompt and workflow is a legitimate business choice. Hiding that an image is AI-generated is a different thing: Etsy, Amazon KDP and Adobe Stock require AI disclosure, Shutterstock refuses AI-generated contributor uploads, and removing provenance to avoid it can breach their terms and mislead buyers. This tool deliberately removes the recipe, not the label.

If the file carries Content Credentials, any change to the file makes the signature report “modified after signing”. That is accurate: the manifest still shows its origin. To keep a pristine signed file, re-export from the original tool with its own metadata options.

How to use it

  1. Drop one PNG or JPEG below — or select a whole batch of up to 200 files.
  2. Check what the original contains.
  3. Press Download clean copy (or Download clean copies (.zip) for a batch). File names end in -clean.
  4. Drop the clean copy back in to confirm the recipe is gone.

Questions

Does removing metadata reduce image quality?

No. The cleaner copies the image data byte-for-byte and only leaves out metadata blocks.

Can I remove the AI label too?

Not with this tool. If a destination requires AI disclosure, keeping the label protects you. For non-AI uses, your image editor’s export options can remove all metadata.

Which formats are supported?

PNG and JPEG. WebP files can be inspected but not cleaned yet.

Is my file uploaded?

No. The clean copy is built in this tab and saved directly by your browser.
