The Metadata Anonymisation Toolkit scrubs many types of files. It was a GSOC (Google Summer of Code) project under the Tor Project and is included in Tails. https://mat.boum.org It has some Python dependencies, but other than that runs on any OS. My one problem with it is that it makes PDFs huge. A 3 MB PDF will be scrubbed into a 30 MB PDF. I talked to the person who made it, and apparently that's an issue with python-hachoi, which is what it uses to create the scrubbed PDFs.
