AI Metadata Remover
Remove the metadata that AI image tools write into their output — including the prompt, the model, the sampler settings and the whole workflow graph.

Your prompt is probably in the file
PNG files can carry arbitrary text records, and generation tools use them liberally. Stable Diffusion interfaces write the full prompt, negative prompt, seed, sampler, steps and model hash into a text chunk called "parameters". ComfyUI stores an entire workflow graph under "prompt" and "workflow". InvokeAI and NovelAI have their own equivalents.
None of this is visible when you look at the image, and all of it travels with the file when you share it.
What gets removed
Every PNG text chunk, JPEG comment, XMP packet, EXIF block, IPTC record and C2PA manifest. The colour profile is kept, because removing it changes how the image looks.
After cleaning, the result is scanned again and you see the difference — including confirmation that the prompt text is no longer present anywhere in the file.
Frequently asked questions
Does this remove the prompt from a Stable Diffusion PNG?
Yes. The parameters chunk and every other text record is removed, and the re-scan confirms it.
Will the image still open normally?
Yes. Only metadata chunks are dropped; the header, palette, image data and colour profile are preserved.
What about the workflow in a ComfyUI image?
Removed as well — it is stored in the same kind of text chunk.
