About:
MAT2 (Metadata Anonymization Toolkit) is a command-line tool designed to remove sensitive metadata from a wide variety of file formats. It strips hidden information such as EXIF data from images, author details from documents, and timestamps from various files. Its primary value is enhancing privacy and security by ensuring that shared files do not inadvertently leak personal or organizational data.
Key Features:
  • Supports over 200 file formats including PDF, JPEG, PNG, and Office documents
  • Provides both a command-line interface and a simple GUI
  • Offers a 'scrub' mode (destructive) and a 'clean' mode (non-destructive)
  • Includes a sandbox feature to safely test cleaning operations
  • Integrates with file managers like Nautilus and Thunar
Use Cases:
  • Preparing sensitive documents for public release or publication
  • Sanitizing images before sharing on social media or websites
  • Complying with data privacy policies by removing PII from files
  • Cleaning files received from external parties before opening them
Alternatives:
  • ExifTool – ExifTool is more powerful for reading/writing metadata but has a steeper learning curve and less focus on privacy-safe scrubbing.
  • ImageOptim – ImageOptim focuses on file size reduction and strips some metadata, but is limited to image formats.
