How should I use this tool?
The detector assesses the submitted file. Compression, resizing or editing can change the input. Keep the original and verify where the image first appeared; a score does not establish authenticity.
What can a result tell me?
Detection results and source estimates can be wrong. They do not prove authorship, ownership or permission to use content. Review the original work before making a decision.
