Overview

ExifTool is the de facto standard for reading file metadata. It extracts EXIF, IPTC, XMP, and many other metadata formats from images, videos, PDFs, and more.

Features

  • Reads a very wide range of metadata formats
  • Batch processing across many files
  • Scriptable command-line interface

Typical election use cases

  • Checking capture time and device details of an image
  • Detecting editing software in a file's history
  • Extracting GPS data when present

Limitations

Social platforms strip metadata, and metadata can be forged. Treat findings as leads to corroborate, not as proof.
