About:
Dangerzone is a tool that converts untrusted PDFs or Office documents into safe PDFs by placing them into a secure sandbox. It works by taking potentially hazardous files and rendering them into a rasterized image format, effectively neutralizing any embedded malicious code or exploits. This process ensures that the resulting safe PDF can be opened without risk on your primary system.
Key Features:
  • Sandbox-based conversion process
  • Support for PDF and Office documents
  • Integration with container runtimes (Docker or Podman)
  • Open-source and privacy-focused
Use Cases:
  • Opening documents from untrusted sources or email attachments
  • Sharing sensitive files while mitigating malware risks
  • Compliance with security policies for external file handling
Alternatives:
  • Qubes OS – A full operating system security solution, whereas Dangerzone is a standalone application for specific file types.
  • Google Docs Viewer – Cloud-based alternative that requires uploading files, while Dangerzone processes files locally for privacy.
