DANGERZONE

Take potentially dangerous PDFs, office documents, or images and convert them to
safe PDFs.

No Network Access

Sandboxes don't have network access, so if a malicious document can compromise
one, it can't phone home

Optional OCR

Dangerzone can optionally OCR the safe PDFs it creates, so it will have a text
layer again

Reduced File Size

Dangerzone compresses the safe PDF to reduce file size

Open Docs Safely

After converting, Dangerzone lets you open the safe PDF in the PDF viewer of
your choice, which allows you to open PDFs and office docs in Dangerzone by
default so you never accidentally open a dangerous document

HOW IT WORKS

Dangerzone works like this: You give it a document that you don't know if you
can trust (for example, an email attachment). Inside of a sandbox, Dangerzone
converts the document to a PDF (if it isn't already one), and then converts the
PDF into raw pixel data: a huge list of of RGB color values for each page. Then,
in a separate sandbox, Dangerzone takes this pixel data and converts it back
into a PDF.
