Dangerzone is a desktop application from Freedom of the Press Foundation that converts untrusted documents (PDFs, office files, images) into safe PDFs by rendering them to pixels inside a network-isolated sandbox and rebuilding the PDF locally. It supports optional OCR and compression, and runs on macOS, Windows, Linux, Qubes OS, and Tails.
Use cases
- safely open suspicious email attachments
- convert untrusted PDFs to safe PDFs
- sanitize office documents before opening
- remove malware and trackers from documents
- OCR scanned documents after sanitization
- open leaked documents without risking compromise
When to choose
- you must open documents from untrusted sources like journalists or activists do
- you want sandboxed, network-isolated document conversion
- you need a cross-platform tool that works on Qubes OS or Tails
- you want optional OCR and PDF compression built in
When to avoid
- you need to preserve the original document's formatting, metadata, or interactivity
- you need to edit documents rather than just read them safely
- you need conversion of formats outside its supported list
- you need a headless server-side bulk conversion pipeline
