Universal file converter

One place to convert between any supported pair of formats.

Requires engine

Universal file converter is fully built. It cannot run in this deployment because a dependency has not been configured.

What it needs: A document rendering engine (LibreOffice headless or equivalent)
Why it is not on yet: Faithful Office conversion needs a real layout engine running server-side. Browser-based approximations lose formatting badly enough that shipping one would be worse than shipping nothing.
