Nobody pays for the conversions that work. They pay for the awkward ones: the DOCX with tracked changes, the HEIC nobody can open, the MXF from a camera, the 4 GB video that has to finish while a browser tab is still open. Doing those reliably means keeping a toolchain installed, patched and fenced off from the files it is fed, and doing it for other people means doing it while strangers upload whatever they like. That upkeep is the product. The convert button is a weekend.

What do I lose by replacing FileChanger?
Honestly: sandboxing, because your version runs files straight through the same toolchain as everything else on the machine; the long tail of format pairs, where the fix is usually a missing font, a filter flag or an upstream bug; queueing and timeouts for large video, which is where the compute bill actually lives; a hosted MCP server and API keys your other tools can reach from anywhere, not just from localhost; somebody else being on call when a LibreOffice or LaTeX upgrade quietly breaks PDF output. If any of those are load-bearing for you, keep paying.
