 - Jpeg (`.jpg`, `.jpeg`)
 - GIF (`.gif`)
 - PNG (`.png`)
-- TIFF (`.tif`, `.tiff`)
 
 Dangerzone was inspired by [Qubes trusted PDF](https://blog.invisiblethings.org/2013/02/21/converting-untrusted-pdfs-into-trusted.html), but it works in non-Qubes operating systems. It uses containers as sandboxes instead of virtual machines (using Docker for macOS, Windows, and Debian/Ubuntu, and [podman](https://podman.io/) for Fedora).
