Have friends that work/have worked as a recruiter :)

PDF files aren't safe either. Even if you gave them a JPEG, they'd just transcribe your data into their own little CV template.

Sure they can, but they'll still try for a DOC file because that makes their lives easier.

The answer isn't to try to "beat" the recruiter with PDFs and JPEGs; the answer is to run away and find a more direct path to the employer.
