MAT - Metadata Anonymisation Toolkit
mat [options] files mat-gui
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.
-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 -l, --list List all supported fileformat -L, --low-pdf-quality Reduced the produced PDF size and quality -v, --version Display version and exit
mat --display mydocument.pdf Display the mydocument.pdf's harmful metadata mat --check *.jpg Check all the jpg images from the current folder
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.

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.
