Drag files in Finder, hold a modifier, and drop on a wheel of outputs. Conversions run entirely on-device through ImageIO, PDFKit, AVFoundation, the bundled CLI tools, and optional ffmpeg/LibreOffice. Includes a --self-test suite (41 checks) and a --convert CLI mode so the conversion matrix can be verified without the UI.
