Open, append, or convert to PDF from Explorer.

You favour the right-click. pdfMachine rewards that. Whether the file under the cursor is a PDF, an image, or a Word doc, the right-click menu has a pdfMachine action for it — no file dialog, no app switch.

Open a PDF. Right-click any PDF → Open With pdfMachine. Skips the File → Open detour. (Want it permanent? Open With → Always makes pdfMachine the default for double-clicks.)
Append to an open doc. Already got a PDF open? Right-click another in Explorer → Apply settings and append with pdfMachine. The new pages join the end — with stationery, digital signatures, and any other “apply on print” settings applied on the way in.
Convert anything else to PDF. Right-click an image, a Word doc, an Excel sheet — pdfMachine converts it straight from Explorer. No opening the source app first.

Three menu items. None of them need a file dialog.

Right-click. You know you love it.
