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
