ExifTool
Extracts hidden metadata from images, documents, and media.
ExifTool is an open-source utility that reads, writes, and edits meta information in a wide variety of files. It allows researchers to extract hidden metadata from images, documents, and media to verify file origins or detect alterations. This capability supports legitimate digital forensics and integrity verification efforts by revealing embedded technical details.
Privacy note. Photos and documents often carry embedded GPS coordinates, device IDs and edit history — strip metadata before sharing files publicly.
