PDF compression from the Explorer menu, with nothing leaving your machine. Native C++ handler, .NET engine.

The context menu is a native C++ COM handler (`IExplorerCommand`, with multi-select) and the heavy lifting sits in a .NET worker — the split exists because a shell handler has to be small and load fast inside Explorer. Compression through Ghostscript, an Inno Setup installer served from the project's own server, and a lifetime licence through Dodo Payments.
