Removing privacy related data from images

To protect your privacy, we recommend to remove respectively anonymize metadata from your images before posting.

A very convenient method for metadata removal is available with MAT, the Metadata Anonymisation Toolkit.

MAT supports wildcards (batch operation), so with mat * you can process a whole image folder for uploading in seconds.

Usage:

$ mat
usage: mat [-h] [-a] [-b] [-L] [-c] [-d] [-l] [-v] [files [files ...]]
