What local AI tools save in a file
Local image generators often store everything needed to recreate an image in the PNG itself. ComfyUI's documentation says it writes two text entries: prompt, holding the API prompt, and workflow, holding the full graph with its layout. Automatic1111 and Forge are widely reported to use a parameters text field, with your prompt, negative prompt, seed, sampler, model, and more.
This tool flags those fields as AI prompt or settings when you scan a PNG.
Why people remove them
- Privacy: a prompt can include names, or details about private projects.
- Protecting your method: a ComfyUI workflow is a complete recipe, and may be the result of months of work.
- Model names: the file can reveal which checkpoints and LoRAs you used, including paths from your computer.
- Client work: you might not want internal settings to travel with a finished file.
Turn it off at the source
If you never want these saved, change your generator's settings. ComfyUI documents starting it with --disable-metadata, and ComfyUI Desktop has a "Disable saving prompt metadata in files" option under Server-Config. In Automatic1111, look in Settings for the options about saving generation parameters to PNG files. The wording varies by version.
Think before you do that. Files saved with no metadata can't be used to recover a workflow, so many people keep metadata in their private archive and clean only the copies that they share.
How to clean a PNG here
- Scan the file in the Metadata checker tab.
- Switch to Image cleaner, and leave Export as on Original format or PNG.
- Clean it, and check the result. The scan should no longer list text metadata.
- Keep your original in a private folder.
PNG output keeps the decoded pixels unchanged, so there's no generation of quality loss.
What it won't do
Removing settings doesn't change how the image was made. A cleaned image is still AI-generated, and some models or pipelines add invisible watermarks to their output, which this tool can't see or remove. Follow the rules wherever you publish, and don't present AI work as a photograph. Our Terms of Use cover this.
Sharing workflows on purpose
Embedded workflows are also a feature. Many people in the community share PNGs so that others can drag them into ComfyUI and learn from them. If you're happy to share, leave the file alone. Think of cleaning as a choice to make for each file, depending on who's receiving it. Also see what Midjourney files store.

A few things to know
Questions, answered.
Where does ComfyUI store workflows?
ComfyUI documents that it writes prompt and workflow as text entries inside PNG files.
Can I recover a workflow after cleaning?
Not from the clean copy. Keep your original file if you might need the workflow again.
Does cleaning change the image pixels?
PNG exports keep decoded pixels without lossy compression. JPG and WebP exports are re-encoded at high quality.
Does it remove invisible watermarks?
No. It removes file metadata only, and anything stored in the pixels stays there.
