How to remove prompts and workflows from AI images
Updated November 13, 2026
Short answer
AI image tools save their settings as text inside the PNG. AUTOMATIC1111 and Forge write a “parameters” chunk with the prompt, negative prompt, seed, sampler and model. ComfyUI writes “prompt” and “workflow” chunks, so dragging your image into ComfyUI loads your whole graph. PicDetox removes these chunks and keeps the image identical.
Where each tool stores it
- AUTOMATIC1111 and Forge: a text chunk named parameters
- ComfyUI: prompt and workflow chunks, as JSON
- NovelAI: Description, Comment and Software chunks
- InvokeAI: an invokeai_metadata chunk
- Midjourney: the prompt in the image's description metadata
Who can read it
Anyone with the PNG: online “PNG info” readers, image viewers that show text chunks, or ComfyUI itself.
Keep the image, lose the recipe
Re-saving as JPEG drops the text chunks but compresses the image again. PicDetox removes the chunks and copies the image data byte for byte.

Questions
Does it remove the AI label too?
It removes Content Credentials and IPTC AI tags as well, but not invisible watermarks such as SynthID. If a platform asks you to label AI images, keep the label.
Can I keep a copy with the prompt for myself?
Yes. PicDetox saves a clean copy by default and leaves your original untouched.
