When you receive untrusted documents, for example, email attachments, *[Dangerzone](https://dangerzone.rocks/)* allows you to convert them into safe PDFs before opening.
<p><i>Dangerzone</i> is created by <a href="https://freedom.press/">Freedom of the Press Foundation</a>, a non-profit that protects public-interest journalism. Edward Snowden and Laura Poitras are on its Board of Directors.</p>
Tails also includes [[*Metadata Cleaner*|doc/sensitive_documents/metadata]] to clean files, but the use cases for *Dangerzone* and *Metadata Cleaner* are very different.
