Take potentially dangerous PDFs, office documents, or images and convert them to safe PDFs.
Download Learn More🦠 Removes malware
Dangerzone destroys malware by rendering your document into pixels in a secure sandbox and reconstructing it locally as a PDF.
🗋 Supports many file types
Dangerzone supports more than 20 file types, including PDFs, all major office-suite formats, and the most common image types.
🔌 Avoids network access
Documents are sanitized in a sandbox with no network access, so if a malicious document can compromise one, it can't let anyone know.
🫴 Provides a public good
Dangerzone is a free and open source project, maintained by Freedom of the Press Foundation (FPF), a nonprofit organization that protects and defends press freedom.
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, Dangerzone takes this pixel data and converts it back into a PDF.
