ComfyUI Image Metadata Cleaner
ComfyUI images can carry workflow or prompt information inside the file, especially in PNG exports.
ComfyUI images can store workflow and prompt data in file metadata. MediaClean checks readable signals and creates a new sharing copy without carrying ordinary metadata forward. Keep the source file if you want to preserve workflow reload information.
Why can a ComfyUI image contain workflow or prompt data?
ComfyUI image-saving workflows can embed execution or workflow information in image metadata. PNG commonly stores such information in text-oriented chunks, while other formats can use different metadata containers.
That information is useful for rebuilding a workflow or auditing settings, but it can also expose details you may not want in a public sharing copy, such as model names or prompt-related data.
Treat cleanup as a sharing workflow. If you want to preserve the ability to reload a workflow, keep a separate original before creating a cleaned derivative.
How to clean ComfyUI image metadata
- Choose the final PNG, JPEG or WebP file you plan to share.
- Review the metadata and file signals detected by the scan.
- Keep the original if you need the embedded workflow or prompt later.
- Create a cleaned copy and review the output scan before sharing.
How do you know cleanup worked?
After the new copy is created, the tool scans again and shows the new size, format and remaining readable signals.
Questions about this tool
Does every ComfyUI image contain a workflow?
No. It depends on save settings and export path, and other applications may strip the data during re-save.
Can the cleaned copy still reload the workflow in ComfyUI?
Do not rely on it. Metadata cleanup can remove information used for workflow restoration, so keep the original.
