       MAT - Metadata Anonymisation Toolkit

SYNOPSIS

       mat [options] files

       mat-gui

DESCRIPTION

       The  Metadata  Anonymisation  Toolkit is a lib (with a CLI and a GUI) created to anonymise
       file's metadata. In essence, metadata answer who, what, when, where, why,  and  how  about
       every face of the data that are being documented. They can be a risk for privacy.

OPTIONS

       -h, --help
              show this help message and exit

       -a, --add2archive
              Add to outputed archive non-supported filetypes

       -b, --backup
              Keep a backup copy

       -c, --check
              Check if a file is free of harmful metadatas

       -d, --display
              List all the harmful meta of a file without removing them

       -f, --force
              Don't check if files are clean before cleaning

       -l, --list
              List all supported fileformat

       -L, --low-pdf-quality
              Reduced the produced PDF size and quality

       -v, --version
              Display version and exit

EXAMPLES

       mat --display mydocument.pdf
              Display the mydocument.pdf's harmful metadata

       mat --check *.jpg
              Check all the jpg images from the current folder

NOTES

       MAT only process metadata, it does not handle file data.  Blame yourself if you are traced
       back because of the data of your files.  MAT is not perfect : In  most  of  the  cases,  a
       forensic  expert  with  a  lot of time can trace back your document.  If you want absolute
       privacy, use plain-text.

BUGS

       MAT does not handle watermaking/tattoos for now.  The --low-pdf-quality option may produce
       heavier PDF for very small files.  You should only use it for big files.
