Local-first processing
For supported tools, the image file itself is read by browser code and Web Workers. AnalyzeImage does not provide an upload endpoint for these workflows. Standard requests for the site application still occur.
- Magic-byte format detection
- Header-level dimension checks
- EXIF/XMP/IPTC normalization
- Privacy-risk rules
- Optional local SHA-256
Cleaning methodology
JPEG metadata segments and PNG/WebP metadata chunks are removed from a new copy. Pixel or compressed scan data is retained on the supported path. Orientation and ICC color information receive special treatment.
- Original file remains unchanged
- Output is reparsed by the interface
- Claims are limited to tested formats and paths
Evidence limits
Metadata is editable. Missing metadata does not prove safety or authenticity. C2PA validation documents signed provenance claims; it is not a general truth detector.
