How Do I Wipe Metadata from Multiple PDF Files?

[thelucas]

I have several hundred pdf files I would like to wipe all metadata from. Is there an easy, preferably free, way to do this?

I am running Yosemite and Adobe Acrobat 9 Pro.

Thanks!

Personally I think the best option would be to look into command line utilities such as convert (part of image magick). I have used it many times in the past to convert pdfs to png files. Another alternative is to Google batch gimp shell scripts.

Thanks. That's beyond my level of comfort. I was hoping for an automator workflow or some software.
