Dangerzone
Dangerzone converts potentially dangerous documents and images into safe PDFs by rendering them in a secure sandbox.
About Dangerzone
Dangerzone is a tool that converts potentially dangerous PDFs, office documents, and images into PDF files. The homepage says it works by rendering each document as pixel data inside a sandbox, then rebuilding it locally as a PDF. The homepage describes this as removing malware, but the source does not describe how thoroughly it does so, so the entry does not make that claim.
The sandbox has no network access, so the homepage states that a malicious document that compromises it cannot send information out. Dangerzone is listed for Windows, macOS, and Linux, with installers for Ubuntu/Debian, Fedora, and Tails, a build-from-source option for other Linux systems, and a beta version for Qubes OS. Pricing is listed as unknown.
