How Midjourney marks images
Midjourney embeds the prompt, version parameters, and job ID inside PNG text chunks (tEXt/iTXt) or JPEG EXIF UserComment fields.
What gets embedded in the file
The original text prompt, aspect ratio, seed number, stylize parameters, and Midjourney software strings.
Lossless cleaning method
Strips ancillary PNG text chunks and EXIF comment fields at byte level without re-compressing image pixels.
Technical limits and policy
Metadata only. Does not alter image content. Disclose AI generation in accordance with platform policies.
How to Clean Midjourney Images
Add your Midjourney file
Drag and drop your JPEG, PNG, or WebP image into Clean on your desktop or mobile browser.

Midjourney Metadata FAQs
What metadata does Midjourney add to image files?
Midjourney embeds provenance records, generator tags, and parameter metadata into file headers upon creation or export.
How does Clean remove metadata from Midjourney images?
Clean parses the file format structure in your browser and drops unwanted metadata blocks without re-compressing image pixels.
Does cleaning Midjourney files degrade visual quality?
No. Clean operates at the binary level and copies compressed image bytes verbatim, ensuring 100% lossless output.
