What the scanner checks
The built-in scanner looks for common EXIF, XMP, IPTC/Photoshop, JPEG comment, PNG text, WebP metadata, C2PA/JUMBF indicators and selected AI-related textual markers when they are present in detectable file structures.
Structural information needed to display an image, such as ordinary image data and some color-management information, is treated separately from removable privacy metadata.
